Abstract

The present invention is a washing apparatus suited for use in washing outside surfaces of vehicles. Fluid is conducted along a conduit that is mounted to a support structure so as to permit selected displacements thereof along a longitudinal axis of the conduit and selected rotations thereof about the longitudinal axis. The fluid conducted through the conduit can be conducted through at least one of a plurality of nozzles that are mounted to the conduit. The conduit is selectively reciprocated along the longitudinal axis by a first driving device. In addition, the conduit is rotated about the longitudinal axis by a second driving device. As the conduit is displaced both about and along the longitudinal axis, the fluid forced through the nozzle is directed toward the outside surface of an object to be washed.

Claims

1. A fluid treatment apparatus suited for use with an apparatus for washing outside surfaces of vehicles, the fluid treatment apparatus comprising:

a first manifold means suited for connection to a source of fluid capable of providing flows of said fluid at a selected first fluid pressure;

a second manifold means suited for connection to a fluid utilization means capable of drawing output flows of said fluid at a second fluid pressure of a value differing from that of said first fluid pressure; and

a plurality of pressure regulation means each connected between said first manifold means and said second manifold means so as to be able to pass said fluid from said first manifold means to said second manifold means at said second fluid pressure such that sums of flows of said fluid passing through each of said plurality of pressure regulation means are substantially equal to corresponding said output flows of said fluid from said second manifold.

2. The apparatus of claim 1 wherein said fluid utilization means comprises a high pressure pump.

3. The apparatus of claim 2, wherein said fluid utilization means further comprises said apparatus for washing outside surfaces of vehicles connected to an output of said high pressure pump to receive said fluid therefrom.

4. The apparatus of claim 1 wherein said selected first fluid pressure has a value exceeding that of said selected second fluid pressure.

5. The apparatus of claim 1 wherein a maximum flow from any of said plurality of pressure regulating means at said selected second fluid pressure is less than said output flow value.
