Abstract: A valve-closing pressure chamber and a valve-opening pressure chamber are arranged on both sides of a main diaphragm inside an outlet shutoff valve. An upper supply/discharge tube and a lower supply/discharge tube are connected to a housing forming the outlet shutoff valve. The upper and lower supply/discharge tube supply and discharge air to and from the valve-closing pressure chamber and the valve-opening pressure chamber, respectively. An opening end, which is on the pressure chamber side, of each supply/discharge tube is obliquely cut relative to the direction of axis of the supply/discharge tube, which increases the opening area of the opening end. This prevents water present in the pressure chamber from adhering to the opening end of each supply/discharge tube and prevents the adhered water from freezing. As a result, operation performance of the outlet shutoff valve is enhanced.

When the pressure within the driveline component increases the first valve closes or remains closed and the second valve opens and fluid is exhausted to the atmosphere. When the pressure within the driveline component decreases, the first valve opens and the second valve closes and fluid flows into the driveline component from an interior portion of an associated vehicle.

Abstract: Arranged in a hydraulic circuit is a valve with an L-shaped duct arrangement, which is formed by a transverse duct 2 and a longitudinal duct 3. Formed in extension of the longitudinal duct 3 is a holding and guiding bore 4, in which a throttling element, comprising a throttle slide 10 and a valve piston 21 that can be displaced therein, can be displaced longitudinally. The valve piston 21 has a passage hole 25, which is connected to the interior of the throttling element and two proportionate annular chambers 17a and 17b. Of these, the proportionate annular chamber 17b is connected to a pilot control valve via a control duct 19. Depending on the direction and pressure of the hydraulic fluid flowing through the L-shaped duct arrangement, the throttling element is moved in or out and extended or compressed in the process.

Abstract: A cartridge relief valve uses a piston design. The piston replaces a tube used in prior art relief valves. The piston makes the inventive relief valve easier to manufacture and more stable than prior art relief valves. This is due to the fact that, for a given size valve, the diameter of the piston is smaller than the diameter of the tube that it replaces. Furthermore, the diameter of the pilot seat of the inventive relief valve is also smaller than the diameter of the pilot seat of many prior art valves.

Abstract: A valve mechanism to control fluid flow between a fluid pumping device and a system that includes an inlet from the fluid pumping device, a first valve, a second valve, a first outlet fluidly connected to the system, and a second outlet. The first valve prevents backflow of fluid when the fluid pumping device discontinues pumping fluid to the system. The second valve checks fluid flow through the valve to the first outlet when fluid pressure at the inlet is less than a first predetermined pressure. The second valve permits fluid flow from the pump through the valve to the system only when fluid pressure at the inlet is greater than the first predetermined pressure. The second valve prevents fluid pressure in the system from substantially exceeding a second predetermined pressure when the pumping device is not pumping fluid to the system.

Abstract: A valve, system, and method for controlling evaporative emissions of a volatile fuel. The system includes a fuel vapor collection canister, an isolation valve, and a fuel tank. The isolation valve includes a housing defining a chamber, a diaphragm movable with respect to the housing between a first configuration and a second configuration, and a coil spring biasing the diaphragm toward the first configuration.

In the first configuration, the diaphragm occludes the aperture, divides the chamber into three sub-chambers, and substantially prevents fuel vapor flow between the first and second ports. In the second configuration, the diaphragm divides the chamber into two sub-chambers and permits generally unrestricted fuel vapor flow between the first and second ports.

Abstract: An externally-mounted, quick-acting trigger assembly for firing blast aerators, air cannons, or the like. The trigger assembly is ideal for high temperature applications involving environmental factors such as excessive heat, humidity, and mechanical shock. The trigger comprises a symmetrical, ventilated housing that internally mounts a hollow piston. A plurality of vent orifices are radially disposed about the housing periphery, and normally covered by a resilient band forming a check valve. The trigger piston comprises a generally cylindrical base and an integral, generally conical bottom that is displaced into and out of contact with a mechanical valve seat. An air passageway through the piston is controlled by a deflectable spherical valve element that is captivated within the piston, for selectively blocking air passage through the piston by contacting an internal valve seat. This construction with internal air passageways facilitates trigger function.

The valve guide is adapted to move the valve stem relative to the valve seat against the force of the relief compression spring to allow fluid to pass from the first fluid side to the second fluid side through a fluid flow passage formed between the valve stem and the valve seat.
