Abstract:
1. A Jet barrel for a spa jet housing having a bore defining a longitudinal axis and having at least one inlet formed therein for passage of pressurized fluid to the bore, the jet barrel comprising: a jet barrel housing defining a barrel bore having a downstream outlet and an upstream inlet, the barrel bore defining a longitudinal axis, the jet barrel adapted for fitting within the spa jet housing, the bore's upstream inlet being adjacent at least one of the one or more spa jet housing inlets; and a rotor, and a spindle pin rotatably supported in the barrel bore and aligned with the longitudinal axis, the rotor being caused to co-rotate with the spindle pin by the flow of water therethrough, and having an inlet supported at or above the bore's downstream outlet and a tubular nozzle outlet angled offset from the longitudinal axis of the jet barrel, the spindle pin having an upstream end and a downstream end, the upstream end being radially guided at an upstream end of the bore and the downstream end having a conical point; and a bearing surface formed at a downstream end of the bore for axially supporting the conical point thereon, wherein the rotor and the spindle pin are rotationally supported on the conical point and radially guided at the upstream and downstream ends.
