ROTARY SPA JET INCORPORATING A ROTATING NOZZLE SUPPORTED BY A RADIAL BALL BEARING INTENDED TO REDUCE CLOGGING OF THE BEARING

摘要

A rotary spa jet of the type which comprises a nozzle rotatably mounted within the end of a spa jet housing by a radial ball bearing, is provided with an internal flow guide to reduce impairment of the free rotation of the nozzle caused by debris in the spa water. The flow guide is positioned within the spa jet housing and acts on a portion of the water flow which reaches and flows through the racial ball bearing to flush and lubricate it. The flow guide includes one or more annular baffled walls which deflect water flow which reduce the amount of water that flows through they bearing and slows clown its rate of flow to promote settlement and collection of debris before it reaches the bearing.
