ABSTRACT:
In a laundry clothes water extracting machine of the type having a flexible diaphragm with an outer and inner surfaces and the inner surface forming a receptacle for receiving wet clothes for extraction of water therefrom, a water carrying reservoir, a rigid housing about the outside surface of the flexible diaphragm, and a pump arrangement for pressurably applying the reservoir water to the space between the outside surface of the diaphragm and the rigid housing to thereby cause the diaphragm to compress against the wet clothes and squeeze the clothes water therefrom and thereafter to return the pressurably applied reservoir water back to the reservoir; the combination of a 24 volt solenoid operated water valve having an inlet coupled to a conventional pressurized water supply and an outlet coupled for supplying water from the pressurized water supply to the reservoir, a step-down transformer with a primary coupled to a conventional A.C. power source and a secondary in a circuit across the solenoid for 24 volt output to the solenoid, and a float operable switch in the reservoir coupled to the 24 volt output circuit to the solenoid for closing the electric output circuit to the solenoid and thereby causing the water valve to open for conventional water supply flow to the reservoir when the reservoir water level falls below a safe level needed to supply the pump arrangement and to open the electric output circuit to the solenoid when the reservoir water level rises to an upper water level for insuring sufficient reservoir water to supply the pump arrangement.
