A slit valve () to selectively restrict the passage of a fluent substance between an interior environment () and an exterior environment () and a method for forming the valve (), the method including the steps of providing at least one layer of film material and permanently deforming the film material to define a valve () for selectively restricting the passage of a fluent substance between an interior environment () and an exterior environment ().

Dispensing valve

A flow control device () and process are provided for controlling the flow of a pressurized fluid substance from a supply system (). The device () includes a housing () that defines an orifice () for communicating between the supply system () that has an outlet end defining a discharge opening (). The devicefurther includes a valve () having a flexible, resilient valve head () that has confronting, openable portions () movable from a closed configuration to an open configuration when the valve head () is subjected to a pressure differential acting across the valve head (). The valve () is located across the housing outlet end discharge opening () so that the valve () and the housing () together define an expansion chamber () between the orifice () and the valve ().

Flow control device and process

An actuating system is provided for a dispenser cartridge that can be mounted on a frame and that has a reciprocatable product-dispensing hollow stem that (A) is biased to an extended position in which the cartridge is unactuated, and (B) is moveable from the extended position to a depressed position in which the cartridge is actuated for discharging the fluent substance through the stem. The actuating system includes a plunger on the frame, and a discharge conduit located adjacent the frame to accommodate relative movement between the discharge conduit and the frame. The discharge conduit includes (A) ml inlet opening communicating with the dispenser cartridge hollow stem, (B) ml outlet opening from which the fluent substance can be dispensed, (C) a passageway between the inlet opening and outlet opening, and (D) an intermediate opening that is in communication with the passageway between the inlet opening and the outlet opening.

Actuating system for a fluent substance dispensing system

A port closure system () including a retention structure (), and a valve (). The retention structure () includes a port () for establishing communication between an exterior environment () and interior volume () that can receive a fluent substance. The valve () includes a flexible, resilient, self-closing, slit-type valve head () with an orifice that is normally closed in an unconstrained condition. The port () has a laterally inwardly facing engaging surface () and the valve has a laterally outwardly facing peripheral surface () that is compressed laterally inwardly by engagement with the surface () to increase the resistance of the normally closed orifice to opening when the head () is subjected to a pressure differential. The system () further includes an annular flange () located to extend over at least a portion of an exterior side () of the valve head () to limit movement of the valve head () towards the exterior environment ().

Port closure system for use with a probe/feed/drain tool

A valve () and flow control element () are provided for use with a dunnage bag (). The valve () includes a valve housing () that carries an actuator () and the flow control element (). The housing () defines a flow passage (), and a seal surface () around the flow passage. The flow control element () includes a peripheral attachment portion (), a resilient, intermediate portion () extending generally laterally inwardly from the peripheral attachment portion and defining at least one flow aperture (); and an imperforate central portion () extending generally laterally inwardly from the intermediate portion and including a seal () for sealing against the housing seal surface with the flow control element in a normally closed position. The intermediate portion of the flow control element accommodates movement of the seal between the normally closed position and an open position away from the seal surface in response to the central portion being subjected to an opening force, thereby permitting flow of a fluent substance through the flow passage and the at least one flow aperture.

Apertured flow control element and housing structure therefor

A dual sealing system () is provided for use with a probe () to allow access to an interior space () from an exterior environment (). The system () includes a housing () defining a port () extending along a longitudinal axis () between an exterior end () of the housing and an interior end () of the housing to establish communication between an exterior environment () and an interior space (); a first flexible, resilient penetratable member () extending across the port at a first location along the axis, the first penetratable member configured to create a seal around the probe with the probe inserted therethrough; and a second flexible, penetratable member () extending across the port at a second location along the axis spaced toward the interior end from the first location, the second penetratable member configured to create a seal after having been penetrated by the probe and the probe has been removed from the second penetratable member.

Dual sealing system for use with a probe

The present invention is directed to a pressure-responsive valve assembly which functions in the nature of a check valve to control fluid flow across the assembly. The assembly includes a valve body which defines first and second internal flow passages, and includes a valve seat through which at least one flow port extends for joining the first and second passages in fluid communication with each other. A flexible, resiliently deformable valve member is positioned in operative association with the valve seat, and can be deflected, in response to a sufficient pressure differential, to move out of sealing engagement with the valve seat, to thereby permit fluid flow through the valve assembly.

Valve assembly

The present invention is directed to a pressure-responsive valve assembly which functions in the nature of a check valve to control fluid flow across the assembly. The assembly includes a valve body which defines first and second internal flow passages, and includes a valve seat through which at least one flow port extends for joining the first and second passages in fluid communication with each other. A flexible, resiliently deformable valve member is positioned in operative association with the valve seat, and can be deflected, in response to a sufficient pressure differential, to move out of sealing engagement with the valve seat, to thereby permit fluid flow through the valve assembly. In the preferred embodiment, the valve seat of the valve assembly defines a compound sealing surface, including first and second sealing surfaces, which cooperate with the deflectable valve member to provide enhanced resistance to reverse fluid flow, with one preferred form of the present valve assembly further including a retention projection which cooperates with the valve member to further enhance resistance to reverse fluid flow.

A valve is provided with a peripheral attachment portion by which the valve may be attached to a dispensing structure through which can be discharged a product from a supply of the product. The valve includes a flexible, peripheral sleeve extending from the peripheral attachment portion. The sleeve has a central elongate portion and two shorter end portions at opposite ends of the elongate portion so that the central elongate portion and the two shorter end portions together define an interior volume. The valve also has a flexible, elongate head extending from the peripheral sleeve. The head includes at least one elongate slit defining two, opposed, elongate, openable regions in the head which are normally closed and which open to permit the discharge of the product therethrough in response to a pressure differential across the head.

Valve for dispensing product

A fuel system for a marine engine has a recirculation cooler which receives a portion of fuel discharged from a fuel pump, cools that fuel, and then returns the cooled fuel to the inlet of the fuel pump to reduce fuel vapor formation and to cool the pump as the cooled fuel flows through the pump. The recirculation cooler is preferably formed of a material of high thermal conductivity and has a water passage adjacent to the fuel passage to reduce the temperature of the fuel that flows through the recirculation cooler. The recirculation cooler is preferably used in high heat applications or with a speed controlled fuel pump, with a pulse width modulated drive, for example. In these applications, during at least some fuel flow conditions, the flow of fuel through the fuel pump may be insufficient to cool the fuel pump motor and may cause increased fuel vapor formation. Desirably, the cooler fuel provided from the recirculation cooler to the inlet of the fuel pump supplements the cooling of the fuel pump motor and reduces fuel vapor formation.
