Abstract:
A water flow control system, comprising:a water flow detecting and signal generating device for detecting a flow of water and operable in response to detection of a flow of water to provide water flow indicative signals; a first timer coupled to the generating device for initiating timing of a predetermined time interval upon commencement of flow indicative signals; a normally closed solenoid actuated valve controlled by the timer for selectively interrupting the flow of water upon an indication from the timer that a predetermined time interval has expired; a second timer for resetting the first timer to an initial state upon a lapse of time during which no signal is received from the generating device; and a double-pole, double-throw solenoid actuated relay having a first pair of normally open contacts operable when closed to supply enabling current to said solenoid actuated valve and a second pair of normally open contacts operable when closed to form part of a latching circuit to maintain the solenoid energized.
