摘要： To provide an outflow prevention device which is capable of preventing refrigerant from flowing out into a vehicle compartment even when an evaporator has ruptured.The outflow prevention device comprises a shut valve arranged in a passage via which refrigerant introduced into a shut valve inlet from an expansion device is allowed to flow to the evaporator, and a check valve arranged in a passage via which refrigerant returned from the evaporator is allowed to flow to an accumulator. A chamber behind a piston fixed to a plug holding a valve sheet and a chamber on a downstream side of the check valve are communicated with each other via a bypass passage, so that differential pressure generated across the check valve by flow of refrigerant through the same can be applied to the shut valve to open and close the same. The valve sheet and the piston are formed to have the same diameters so as to prevent the shut valve from being influenced by introduced pressure, thereby enabling the shut valve to be operated only by the differential pressure generated across the check valve.

摘要： In a flow control apparatus, a fluid pressure is introduced from downstream of a metering orifice to a rear room of a spool while a relief valve in the spool is assembled in advance. A front section of a relief valve sub-assembly is press fitted to a hole provided on the spool and is opening to rear room of the spool so that a receiving room of a valve body in a relief valve casing communicates to a bypass path. A communicating path provided in a rod communicates to the rear room of the spool through outside of the relief valve sub-assembly. The relief valve casing is received in a receiving hole provided in the spool and a cylindrical room between the relief valve casing and the receiving room is used as a part of a communicating path.

摘要： A method of determining flow through a valve includes determining a first differential pressure across the valve. The valve is bypassed and a second differential pressure is determined across the valve. A flow decision is determined for the valve based on comparison of the first and second differential pressures. A method of testing a relief valve in a reduced pressure backflow preventer assembly includes determining a first differential pressure across an upstream check valve during a no flow condition. The upstream check valve is bypassed for the purpose of opening a relief valve, and a zone vent is opened.

摘要： A safety device (1) for a fluid transmission has a diaphragm (4) which is arranged deflectably in a feed passage (8) and which has at least one through opening (2) for the fluid. A return passage (10) for the fluid from the chamber of the consumer (9) is of such a configuration and arrangement that it can be opened and closed by deflection of the diaphragm (4), wherein the diaphragm (4) is of such a configuration that, when the fluid flow in the feed passage (8) falls below a given value, the return passage (10) is opened. The pressure in a pressure chamber (9) of a consumer can be let off by the device (1) when a pump (7) is no longer conveying.

摘要： A valve system in a power steering system is disclosed. It includes a spool valve which is slidably located in a valve bore for by-passing an excess fluid at high vehicular speed in response to the pressure differential across an orifice. A control rod is slidably located in the spool valve and has at the end a metering portion for maintaining a limited flow volume when the spool valve is moved to close a by-pass port with the increase of a working pressure in the power steering system.

摘要： A bypass valve with a tubular housing having an inlet at one end, a main outlet at the other end and a bypass outlet between the ends. A larger-diameter valving element controls the flow of fluid from the inlet to the main outlet, and a smaller-diameter valving element which is coaxial with the larger-diameter valving element controls the flow of fluid from the interior of the housing to the bypass outlet. The valving elements are mounted on a rod which confines them to movement in and counter to the direction of fluid flow from the inlet to the main outlet. Each valving element is movable by the fluid to an infinite number of positions in each of which they permit the fluid to flow to the respective outlets at a different rate. The smaller-diameter valving element is movable against an annular seat to seal the bypass outlet from the interior of the housing. The larger-diameter valving element can cooperate with a seat or is reciprocable in a tapering section of the housing so as to allow for continuous flow of fluid between the inlet and the main outlet. The rod is rigidly connected to the smaller-diameter valving element and is rigid with or reciprocable relative to the larger-diameter valving element.
