    摘要: A hydraulic valve assembly for controlling a clutch in a vehicle transmission. The valve assembly includes a housing with a first port for connection to a source of pressurized hydraulic fluid, a displaceable sealing piston disposed within the housing, a valve spring for displacing the sealing piston, a snap-spring having first and second equilibrium positions, and an overstroke spring. In the first equilibrium position a spring force displaces the sealing piston to uncover the first port to enable fluid flow through the valve, and in the second equilibrium position the valve spring displaces the sealing piston to block the first port to block fluid flow through the valve. Moving from the first equilibrium position to the second equilibrium position includes displacing the overstroke spring.

    摘要: A safety relief valve is provided that comprises a body comprising a chamber therein and an inlet and an outlet, the inlet comprising an inlet valve seat; a disk member closable on the inlet valve seat; and a mechanism in the body biasing the disk member to rest on the inlet valve seat with a set force such that when the pressure in the inlet exceeds a set pressure resulting from the set force, the disk member is lifted from the inlet valve seat, the mechanism comprising a combination of a coil spring and one or more disk springs stacked in series with the coil spring.A method of preparing a coil spring for use in a pressure relief valve comprises measuring the spring rate of the coil spring and; modifying the spring so as to modify its spring rate to be within ±2% of a desired spring rate.

    摘要: The valve assembly has inlet and outlet members with valve elements disposed between the two members. The valve is a resilient membrane having one or more through holes. When there is no pressure differential across the valve, the hole walls in the membrane collapse inwards closing off the valve against liquid flow. At or above a threshold pressure differential across the valve, the membrane is stretched which opens up the hole or holes to allow the passage of liquid.

    摘要: A relief valve assembly includes a valve element mounted for movement along a valve axis between a sealing position and a relief position. A spring arm engaged with the valve element urges the valve element toward the sealing position. The spring arm has a free end engaged upon a cam surface. Movement of the valve element between the sealing and relief positions causes movement of the free end of the spring arm along the cam surface. Movement of the valve element toward the relief position causes movement of the free end of the spring arm along the cam surface increasing spacing of the free end of the spring arm from the valve axis and increasing spring force of the free end of the spring arm upon the cam surface. This maintains a substantially constant, predetermined spring force component urging the valve element toward the sealed position.

    摘要: A pressure relief valve for releasing fluid through a vent in a railway tank car, tank trucks and similar vessels. A valve disk is normally biased in a closed position by a plurality of constant-force springs of laminated steel tapes on drums supported on upright angle brackets symmetrically arranged around a valve seat. The pressure at which the valve opens is determined by a preselection of the number of springs, laminated tapes per spring, and the restoring force of each tape.
