摘要： An improved swivel coupling is provided for use with a pool cleaner, particularly for use in connecting a pool cleaner of the type powered by a suction or vacuum source to a flexible vacuum hose which is connected in turn to the suction side of conventional pool water filtration equipment. The swivel coupling comprises outer and inner part-spherical ball segments adapted for respective connection to the vacuum hose and to a water flow port on the pool cleaner, wherein the outer ball segment defines a socket for rotationally receiving and supporting the inner ball segment in a manner to accommodate substantial angular and rotational swivel displacement therebetween. A plurality of generally axially extending ribs are formed within the socket for rotationally supporting the inner ball segment with minimal contact area, and to define therebetween a plurality of axially elongated recessed channels. The socket further includes an annular and relatively narrow width seal ring disposed generally at a distal end thereof for normally engaging the inner ball segment to restrict ingestion of debris and grit to the interface between the outer and inner ball segments. Any ingested grit and debris tends to flush through the recessed channels for passage to the pool filtration equipment, substantially without binding or interfering with relatively free swivel movement of the coupling.
