ABSTRACT:
A diaphragm valve for a pool cleaner which utilizes a conventional cleaning head (30) attached with a mounting foot (32) to a cleaning disc (34). A screen (36) is inserted into the foot and an outer sleeve (38) is mounted within the head leaving a gap (40) in between. A restricting jacket (56) is slideably mounted on the sleeve and is urged into a position that restricts a water flow path from the gap, by an adjustable bypass valve (68) superimposed on the jacket. A compression spring (96) maintains the jacket position and a valve diaphragm (98) receives pool water from a pool pumping system and oscillates open and closed causing the cleaner to be propelled by a hydraulic pulsation. When the diaphragm is momentarily closed the bypass valve permits the jacket to be slid to an open position by negative pressure of pool water bypassing the diaphragm permitting full water flow through the cleaner.
