| A system and method for operating a solenoid valve is disclosed. The solenoid valve is operated by moving a first valve element (4) with respect to a second valve element (6, 7) a first distance. And then pulling the second valve element (6, 7) with the first valve element (4) a second distance where the second valve element (6, 7) moves against resistance from a seal (8) and where the movement of the second valve element (6, 7) opens a gap with respect to an orifice (10). The second element (6, 7) then moves a third distance under spring load to open an increased gap with respect to the orifice (10). | ||||||

| A method and an apparatus for opening/closing a valve are provided. The method includes the steps of varying a position of a seat assembled into an inner side of a fluid passage of a valve body using a pneumatic pressure or a magnetic force so as to be separated from a turning radius of a valve member for opening/closing the fluid passage, rotating the valve member in a forward or reverse direction by an actuator, rotating the valve member in the forward direction and opening the fluid passage, rotating the valve member in the reverse direction, and returning the position of the seat so that an inner side of the seat is sealingly contacted with an outer face of the valve member and closing the fluid passage. | ||||||
| 56 | Servo-valve | US243847 | 1988-09-13 | US4875659A | 1989-10-24 | Carl H. Hafele; Manfred Weyand |
| In a servo-valve, a metal bellows (70) is fitted onto an end section (66) of valve stem (26,42) lying at a distance from the seal (22), one end of said metal bellows (70) being supported rigidly in housing (72), while its other end engages the end of the stem. The metal bellows (70) are located in a pressure chamber (62) which is connected by a condensate coil (74) to the valve intake (12), whereby the cross-sectional area of the metal bellows (70) is made to match the area of the passageway of the valve seat (16). In this way, it is possible to achieve an overall compensation of the forces at the seal (22) or a desired additional load in the closed or open direction. | ||||||
| 57 | High pressure regulator valve | US663811 | 1984-10-19 | US4620562A | 1986-11-04 | Amos Pacht |
| A pressure regulating valve for controlling pressure in high pressure hydraulic circuits includes a closure member with an integral control piston and a conical seating surface cooperable with a complementary surface on a seat member. The valve closure member is biased in the closed position by an actuating mechanism including a pressure gas piston and cylinder arrangement utilizing a flexible diaphragm for sealing the actuator pressure chamber. The effective cross-sectional area of the control piston is large enough to minimize the differences in cross-sectional areas on the closure member exposed to pressure fluid between the valve closed and valve open positions whereby a minimum variation between the valve opening pressure and the control pressure is experienced. The increase in pressure in the actuator pressure chamber resulting from movement of the valve from the closed to open positions substantially offsets the change in effective face areas of the closure member to further minimize the difference between the valve opening pressure and the steady state regulated pressure. | ||||||
