A leak proof, completely sealed solenoid valve, comprising a housinghaving a fluid flow path controlled via an electrically operated mechanism to control a flow; the mechanism comprises metallic coilcoiled around a bobbinsupported by a magnetic bracketwith terminal pinsconnected to the bobbinfor receiving electrical input to facilitate an energized and de-energized state to control the movement of a poppetshaft that obstructs the flow; wherein, the bobbincomprises micro-melting fins, thereby housing over molding creates strong bond between two materials; a permanent weld is created between the bobbinand the housingto prevent internal leakage; and the completely sealed solenoid valve limits emissions and evaporations of the volatile fuel components into and from the valve, and contribute to reliability and robustness of the product by completely sealing the nozzle and housing using laser welding.

The invention relates to a dual path dual purging system and valve assembly for turbo boosted engines. More specifically, the invention provides an integrated valve assembly connected to facilitate the operation of the low flow valve as a pilot valve for the high flow valve and a system to implement it on turbocharged or supercharged engines. The invention relates to a dual path dual purging system with two purge valves connected to facilitate the use of the low flow valve to be operated as a pilot valve for the high flow valve. This smart routing provides pressure compensation for the high flow valve, when the valve is enabled. This decreases the requirement of force for the high flow valve and gives an option to install a smaller cost efficient solenoid valve.

A ventilation arrangement for the head space of the fuel tank of a vehicle comprises a switchable main valve intended for adjusting an arbitrary pressure in the head space of the tank. By way of the opening position of the main valve, a connection between a connection () intended for connection to the head space and a connection () intended for connection to the surrounding atmosphere is established, wherein the main valve is assigned a pilot valve, which opens during a first path element of a switching movement, wherein the main valve only opens following this first path element. Because of the small cross section of the pilot valve and the pressure relief that materialized through its opening, the switching power can be reduced and a smaller size drive can be employed.

A non-return valve includes a valve housing having at least one inlet, at least one outlet, a first valve seat and a second valve seat; and an at least partially flexible sealing member forceable into a scaling engagement with the first valve seat in response to a first differential pressure and forceable into a sealing engagement with the second valve seat in response to a second differential pressure.

A flow connector for a valve, including a body in which a flow channel is formed that is made up of a first port, a second port and an opening area to receive a movable plug, whereby the ports can be flow-connected through the opening area. The valve having a flow connector is configured and refined in such a way that the volume of fluid that flows through the flow channel per unit of time can be set without any problem wherein the cross section surface area of the flow channel in the opening area is configured to be constant along a first height of lift and to be variable along a second height of lift. A solenoid valve includes the flow connector according to an embodiment of the present invention.

A valve is described having an inlet, an outlet, a sealing element and a device to generate a magnetic field, whereby the sealing element can be moved at least partially by the device and whereby the sealing element connects the inlet to the outlet in a fluid-conducting manner in that the sealing element lifts off at least partially from a valve seat wherein the sealing element is made at least partially of a foam element that can be deformed by the magnetic field.

A valve includes a housing having an inlet (), an outlet () and a movable sealing member () which allows the inlet () and the outlet () to be connected in fluid communication with each other, the sealing member () having associated therewith effective areas () to which pressure can be applied, and sealing areas (), and the sealing member () further having associated therewith a sealing seat () for sealing the inlet () from the outlet (). In order to provide a valve by which pressure can be relieved in a very short time, the sealing member () has associated therewith a conduit () by which the inlet () and the outlet () can be connected in fluid communication with each other when the sealing member () rests on the sealing seat ().

A system for the metered feeding of volatile fuel components, in particular into the intake manifold of an internal combustion engine of a motor vehicle, includes an electromagnetic canister-purge valve which is actuatable in proportional pulse-width modulation, and a closed-loop control circuit with which, for the purpose of compensating for external interferences, the coil current of the canister-purge valve is adjustable. The system is characterized in that at least one device provided for detecting a variable parameter that includes at least one of a mass flow through the valve, a volume flow through the valve, a distance between the valve seat and the sealing element of the valve, and a CHportion in the volume flow. The coil current is adjustable as a function of the parameter.
