Abstract:
A full flow diaphragm valve for a pulsating submersible pool cleaner having a flanged hollow cleaning head attached with a mounting foot to a cleaning disc comprising;a screen disposed within a pool cleaner mounting foot for protecting the cleaner from ingesting extraneous debris,an outer sleeve mounted within a hollow cleaning head, said sleeve configured to have a gap between said sleeve and the hollow cleaning head,a slidable restricting jacket disposed upon the outer sleeve for both bypassing and constricting flow of pool water from the gap between the outer sleeve and the cleaning head,an adjustable bypass valve superimposed onto the restricting jacket, having means to adjust negative pressure at which a flow of pool water is circumvented through said gap,a compression spring between the jacket and the bypass valve for sealing and maintaining jacket position relative to the outer sleeve, anda valve diaphragm having an inner conduit disposed within the outer sleeve for directly receiving pool water and oscillating between an open and closed position causing a pool cleaner to produce a hydraulic cyclic pulsation, further, when the diaphragm is momentarily closed said bypass valve permits the jacket to be slid to an open position by negative pressure of pool water allowing bypassing the diaphragm, granting full flow of pool water through a pool cleaner.
