Abstract: A fluid valve which opens for a predetermined time before automatically closing. The valve (101) incorporates a control means including a control chamber (103), a first/inlet passageway (102) and a second/outlet passageway (120). A flow control element (104) is provided in one of the passageways (102) or (120). A biasing means (117) normally biases the valve to a first/closed position (FIG. 3). An activation means (113) is adapted to move the flow control element (104) to an activated position (FIG. 4) wherein flow of fluid is then permitted for a predetermined time.

Abstract: A valve component (1), formed at least partly of resilient material, including a body portion (2), of generally overall cylindrical shape, a radial recess (3), provided within an end surface of said body portion, and a peripheral flange (5), extending outwardly from said body portion adjacent to said radial recess. The peripheral flange (5) of the valve component (1) is adapted to be secured to a valve casing in a manner such that axial movement of the valve component (1) is permitted between an open position, wherein flow of fluid is permitted between an inlet and an outlet, and, a closed position, wherein the flow of fluid is prevented.

Abstract: A valve device (1) including a fluid inlet (4), a fluid outlet (5), a valve seat (6), a valve member (3) movable relative to a valve seat (6), a control chamber (12), the volume of the chamber being variable depending on the position of said valve member (3), a fluid passageway (7) formed in said valve member (3), providing fluid communication between said fluid inlet (4) and said control chamber (12), a flow control element (8) provided in said fluid passageway (7) such that only a small flow rate is permitted to flow in said fluid passageway, a relief port (9) providing fluid communication between said control chamber (12) and either said fluid outlet (5) or an external outlet, and, a control means to control the position of said valve member (3), either directly or indirectly, and to thereby control the operating of said valve device (1), the control means including a plunger (2) selectively actuated by a solenoid (10).

Abstract: A valve device to control fluid supplied to a tank. The valve device includes a fluid inlet, a fluid outlet to expel fluid to the tank, a valve seat, defining an opening through which fluid is adapted to flow from the inlet to the outlet, a valve member, movable relative to the valve seat between an open position and a closed position, and, a control mechanism to operate said valve device. The control mechanism includes a control chamber, a fluid passageway between the control chamber and the inlet, a flow control element within the fluid passageway, a relief valve, movable between an open position and a closed position to selectively expel fluid from the control chamber to a relief port, and, a relief valve activation mechanism, to control the operation of the relief valve according to an amount of fluid in the tank.
