Abstract
There is disclosed a device for effecting the oscillating movement of a fluid nozzle. The device consists of a housing having a fluid inlet and a fluid outlet, a fluid inlet being adapted to allow fluid under pressure to enter the housing. An impeller is rotationally mounted within the housing positioned in the path of the fluid inlet such that fluid under pressure will rotate the impeller. A gear system is mounted within the housing and is operatively connected to the impeller, and includes a gear arm operatively driven by the gear system at one end and connected to an actuator arm at the other end. The actuator arm interconnects the gear arm with a fluid ejection nozzle such that the rotational movement of the impeller by fluid under pressure causes the gear system to rotate, which in turn rotates the gear arm, causing a concomitant reciprocating movement of the actuating arm and the fluid ejection nozzle. A device such as a shower head connected to the fluid ejection nozzle will similarly realize an oscillating movement.
