Abstract:
A spa jet for delivering water from an upstream source of water under pressure to the interior of a spa, the water containing debris, the spa jet comprising:at least one housing having an inlet tube communicating with the source of water and a chamber wall defining a generally cup-shaped chamber extending downstream from said inlet tube along a common axis therewith; a radial ball bearing having an outer race secured to said chamber wall adjacent a downstream end thereof and an inner race supported by said outer race for rotation about said axis; a nozzle member fixed to and carried by said inner race; at least one nozzle passage extending axially through said nozzle member, angularly and radially offset from said axis, to eject a jet of water which creates a turning moment that rotates said nozzle member about the central axis; a flow guide mounted within said chamber wall, said flow guide including: a generally cup-shaped inner wall mounted within said chamber wall; a flow tube connected to said inner wall extending therethrough positioned to direct water flowing through said inlet tube into said nozzle passage, said flow tube also permitting some water to pass to said radial ball bearing; and at least one baffle wall extending axially from said inner wall substantially around said flow tube, spaced radially therefrom, to reduce the amount of debris that passes through the radial ball bearing.
