ABSTRACT:
A spray device having a plurality of rotating nozzles directs narrow streams of a high pressure fluid in a circular pattern against a vehicle being cleaned in a car wash installation. A conduit for supplying the high pressure fluid to the nozzles is rotatably mounted within a lower generally watertight housing. A front end of the fluid supply conduit extends outwardly of the housing, and a rear end of the conduit is connected to a source of the high pressure fluid by a rotary union. The nozzles are mounted on the ends of T-shaped fluid suppy tubes which extend radially outwardly from the extended front end of the supply pipe. A motor is mounted within a generally waterproof upper housing which is mounted on the lower housing and is generally isolated therefrom. The supply conduit is rotated by the motor which is connected thereto by an endless drive belt which extends through a small opening which provides communication between the two housings. Mounting of the motor in the upper housing shields the motor from the high pressure spray fluid and possible fluid leaks, yet allows heat from the motor to be dissipated by the housing walls into the ambient air to prevent overheating of the motor.
