Rotatable hose coupling

摘要: A rotatable hose coupling (10) is provided for use with a pool cleaner (12), particularly of the type powered by suction or vacuum source via flexible (16) like connected to side conventional water filtration equipment (14), wherein mounted inline along and responds cyclic pressure differentials index through rotational increment each time (14) turned on off. The comprises tubular plunger (28) having one end received axially slidably within cam housing (34) defining an opposed spaced-apart pair surfaces (48, 50). At least radially extending pin (52) carried engages 50) rotatably relative in response axial back forth displacement (34).
