    摘要: Known water supply systems are fed from a source of water such as a tank (6) via a pump (5) to outlets which are occludable by means of a cock (C1-C3). A water pressure sensitive electrical switch (S1) is located downstream of the pump (5) and upstream of the outlets. The switch (S1) is connected in series with an electrical supply for the pump and turns the pump on in response in a drop in water pressure downstream of the switch. Similarly the pump is turned off in response to water pressure downstream to the switch reaching a predetermined minimum pressure, A control system is disclosed in the form of a timer (T) connected in parallel with the pump (5) and energized via the switch (S1). A normally closed safeguard switch (S2) is connected in series with the pump and rendered non-conductive by the timer (T) being energized for a predetermined period. The safeguard switch (S2) prevents the pump (5) operating continuously for more than a predetermine period, typically 15-30 minutes, As a consequence leaks in the system supplied by the pump (5) do not result in excessive water loss from the tank (6), A system and method to prevent water loss in a reticulated town water supply system is also disclosed by means of a flow detector (FD), a timer (T) and a normally open solenoid valve (SV).

    摘要: A magnetic control valve is provided in a suction powered pool cleaner (10) of the type for vacuuming dirt and debris from submerged floor and side wall surfaces of a swimming pool. The pool cleaner comprises a head defining a suction inlet (34) for vacuum inflow of water and debris into a plenum chamber (40), and further through a suction tube (42) adapted for connection via a vacuum hose (14) to a conventional pool water filtration system (12). The control valve includes an oscillatory valve member (64) movable between open and substantially closed positions relative to an upstream end of the suction tube to produce pressure fluctuations causing the cleaner to advance in steps over submerged pool surfaces. Oscillatory driving of the valve head is assisted by permanent magnets (74, 76, 78) mounted on the valve member and cleaner head to generate repulsion forces as the valve head respectively approaches the open and closed positions.

    摘要: A fluid pressure amplifier comprises a pipe for flowing fluid and having an array of holes formed therein through which fluid can flow from within the pipe in use and resiliently-movable obturator means adjacent the pipe and operatively responsive to fluid inlet pressure in the pipe, in which fluid inlet pressure causes the obturator means to oscillate between conditions which alternately permit and prevent fluid from passing through the holes, whereby the fluid leaving the pipe has a pulsed increased pressure. The amplifier is intended for use especially to increase the pressure of water flowing through a pipe submerged in a river, to provide a pumping action to a higher level.

    摘要: The valve comprises a chamber formed by a body and bonnet and having an intermediary plate through which a central shaft extends, a rotor being fitted around said central shaft and being submitted to the action of the fluid flowing into said chamber, said body having fluid outlet bottom orifices being each closed by a respective stopper, said stoppers being prised open by means activated by a reducing gear connected to said rotor. This valve is characterized in that it comprises a central device by means of which the fluid passage towards the rotor is controlled and can even be totally blocked in order to thus adjust the time during which each outlet will be held open, and also in order to keep a given outlet open and all of the remaining outlets closed when the valve has been arrested.

    摘要: A valve assembly (10) includes a refrigerant inlet port (18) and a refrigerant outlet port (19) having a restricted opening (15), with the inlet port opening at least 2 times larger than the restricted outlet port opening. The valve includes components for opening and closing the inlet port (18) in response to valve cavity pressure between the inlet and outlet ports. The larger inlet port (18) relative to the restricted outlet port (19) provides for rapid pressure buildup in the valve cavity (24) when the inlet port is open which, in turn, causes rapid closing of the inlet port. The valve (10) is capable of rapid cycling rates, highly effective for small refrigeration or cooling apparatus, as well as for controlling pressure in other applications requiring pressure regulation.
