A fluid connector with adjustable flow control includes an adapter having a first threaded portion, a sealing surface and an orifice. The fluid connector also includes a valve body having a second threaded portion for engagement with the first threaded portion and a central body passage connected to at least one port. Upon rotation of the valve body relative to the adapter, the port is displaced axially relative to the sealing surface thereby effecting a change in fluid flow through the fluid connector and into or out of the orifice.

A self-sealing end fitting including an adapter receptive of an NAS specified fitting and a valve biased to a closed position, where the valve opens when mated to the NAS specified fitting.

Self-sealing end fitting

A coupling assembly is provided that includes a first coupling member removably securable in an apparatus having a port that includes a receiving groove, a retaining surface and a resilient locking member receivable in the receiving groove. The first coupling member includes a body extending along an axis from a leading portion configured for receipt within the port of the apparatus to a trailing portion configured to releasably connect the first coupling member to a second coupling member. The body includes a rib having a ramp tapering outwardly in a direction way from the axis and a shoulder tapering inwardly toward the axis. The coupling member and port are sized such that upon insertion of the first coupling member into the port, the resilient locking member travels up the ramp and then contracts becoming trapped between the shoulder and the retaining surface to secure the first coupling member to the apparatus.

A releasable coupling assembly for connecting two members is provided that includes a first member having an exterior surface with a receiving portion and a second member having a hose adapter and a sleeve valve positioned within the adapter. The sleeve valve is in slidable communication with the adapter and includes at least one socket aperture that includes a mating ball that contacts at least one longitudinal groove in the adapter that includes a first and expanded radial portion. When the members are secured together, the ball of the sleeve valve is retained in the receiving formation of the first member by the first radial portion of the longitudinal groove of the hose adapter. When the members are pulled apart for disconnection, the sleeve valve initially remains engaged with the first member until the ball comes into contact with the expanded radial portion of the longitudinal groove of the hose adapter and the ball departs the receiving formation of the first member, such that the valve is completely or almost completely closed prior to disconnection of the members.

Releasable coupling assembly

A fluid actuated ball check valve assembly having an annular housing containing a ball valve. The annular housing has a first end and a second end. The annular housing defines a fluid passageway having a passageway axis extending therethrough. A fluid actuated ball valve is pivotally mounted in the fluid passageway. The ball valve defines a bore having a bore extending therethrough. Resilient members, such as a sleeve in contact with a coiled spring, engage the ball valve to maintain the ball valve in the fluid passageway. Pressurized fluid in the fluid passageway at the first end of the annular housing causes the ball valve to pivot from a closed position to an open position to allow fluid to flow through the fluid passageway from the first end to the second end of the annular housing. When pressurized fluid is not acting upon the ball valve at the first end of the annular housing and the ball valve is maintained in a closed position, fluid is prevented from flowing through the fluid passageway from the second end to the first end of the annular housing.

Fluid actuated ball check valve assembly

A quick disconnect fluid coupling for a liquid-cooled, preprogrammed card for an aircraft communication or navigation system, the coupling being made up of male and female coupling elements which are closed to flow in the free or uncoupled state and which are open to flow when coupled. The male coupling element has an integral pressure relief feature which operates in two phases. In a first phase the male coupling element remains closed to fluid flow, but accommodates an increase in fluid pressure by movement of an annular valve sleeve within an outer annular member to increase the fluid volume within the annular member. In a second phase an end of a valve member of the male coupling element is biased away from sealing engagement with an end of the annular valve sleeve by fluid pressure, against the biasing effect of a return spring which is trapped between the annular valve sleeve and a perforate annular retainer that is affixed to an opposed end of the valve member, to permit fluid to be dumped from the coupling element.

A frangible fluid couping wherein at least one coupling part includes a self closing valve. Frangible interlocking component interconnect the coupling parts under normal conditions and the interlocking structure includes weakened portions which fracture upon the coupling being subjected to severe impact, such as during an aircraft crash, permitting the coupling parts to separate. The frangible interlocking component include manually releasable structure permitting the coupling parts to be selectively disconnected for test purposes, and a safety lock is utilized to prevent inadvertent release of the interlocking structure.

Reconnectable frangible ball valve coupling

A ball valve connector of the frangible crashworthy type wherein two fluid flow connector body halves are interconnected by fracturable elements. Each body half includes a ball valve within a flow passage pivotally mounted on diametrically located pins. The pivot pins and valves are capable of displacement in the axial direction of fluid flow to compensate for manufacturing tolerances and provide maximum sealing characteristics. Each valve is rotatable 90.degree. between open and closed positions, and a stop projection defined on each valve cooperates with a spring biased stop ring providing positive retention of the valve in the closed position.
