    • A shuttle valve 8 includes a valve body 9, a shuttle 10, and an actuator mechanism 11. The shuttle valve 8 includes inlet ports 37 and 39 and outlet port 40. The shuttle 10 moves between first and second at rest positions to selectively connect one of the inlet ports to the outlet port and isolate the other inlet port from the outlet port. The actuator mechanism 11 includes first and second springs 63 and 66 and moves the shuttle 10 from one of its positions to another when a set pressure differential is attained between the inlet ports. The actuator mechanism 11 moves a partial stroke distance to move the shuttle 10 between its at rest positions and moves a full stroke distance to additionally open fluid communication between one of the inlet ports and the shuttle 10.

    • A gas safety valve (1) is provided which has a valve chamber (7) within a housing (2), and a gas inlet (3) and outlet (5) respectively communicating with an inlet and outlet end of the valve chamber. A valve (14) is disposed in the valve chamber (7) for allowing gas to flow from the inlet to the outlet when the valve is in an open position, and preventing gas flow when the valve is in a closed position at either end of the valve chamber. The valve may include a piston having a tortuous gas transmitting opening therein, the resistance to gas flow caused by the tortuous opening rendering the valve responsive to slight variations in gas pressure differential between the inlet and the outlet. A resilient spring (17) is provided which extends between the outlet (5) and the valve (14). The spring (17) urges the valve into the open position, and allows it to reversibly move to a closed position against the outlet when the pressure differential between the inlet and outlet of the valve chamber becomes sufficiently high to overcome the resistance of the spring (17).

    • The slide valve includes an outer (1) and an inner (4) valve housing. End pieces (2, 3) and retaining end members (5, 6) keep the inner valve housing stationary within the outer valve housing and a fluid flow channel (24) of cylinder shell shape is formed between the outer and inner valve housings. In the wall of each end of the inner valve housing a set of fluid flow openings (21, 22) is provided. In addition to openings the retaining end members (5, 6) the path of flow through the slide valve is formed by the fluid flow channel (24) and the fluid flow openings (21, 22). The path of flow is blocked by the valve slide (7) which has end surfaces of unequal areas cutting off those fluid flow openings (21) of the inner valve housing (4) which are situated at the end of the valve slide having the larger area, in response to a fall of pressure of a predetermined magnitude arising across the slide valve. By means of friction members (15, 16) arranged at the valve slide and having frictional engagement with the inner valve housing (4) and setting members (10, 18, 19) arranged in the valve slide it is possible to set the pressure (= the fall of pressure across the valve) at which the valve closes fairly independently of the dimensions of the flow-restricting flow channels and openings (21, 22, 24) of the slide valve.

    • A fluid release valve includes valve housing (VH) coupled between a pump and an outlet pipe, VH chamber providing fluid from its inlet and outlet when the pump starts, and fluid release orifice (FRO) draining outlet pipe fluid flowing back into the VH when the pump stops; and check valve (CV) combination having a CV shuttle that moves towards/away from the inlet/outlet and an internal shuttle chamber (ISC), and having a CV that moves towards/away from the inlet/outlet within the ISC. The CV combination responds to a pumped fluid pressure when the pump's pumping and stops the fluid from flowing from the inlet around the CV shuttle and out the FRO. The CV combination responds to a fluid differential pressure (FDP) when the pump stops and allows the outlet pipe fluid to drain out the FRO until the FDP reaches an equilibrium.
