ABSTRACT:
A brush assembly, attachable to a pressurized water line, produces at least two alternating pulsating jet discharges of water. One discharge comprises a linear stream and the other comprises a spray. A nozzle housing detachably mounted on the head of the brush assembly is employed to deliver the intermittently, interrupted or pulsating water jet discharges. Water passing through the brush assembly and the housing drives a turbine blade assembly in the housing. In turn, the turbine blade assembly rotates rotatable valve member at a rotary speed dependent upon the initial pressure of water entering the brush assembly. Water flows through an inlet of the housing through two flow paths. In one flow path, water flows through a valve port in the valve member and out through the discharge orifices in the housing. In the second flow path, water flows around the valve member and out through the discharge orifices and housing. The rotation of the valve member cyclically interrupts water communication between the inlet and the discharge orifices along the first flow path. The configuration of the rotating valve port, the arrangement of the orifices and the second flow path maintain back pressure at the rotating valve port at a substantially constant level regardless of the rotary position of the rotating valve port.
