Cyclically varying pulsating fluid supply system
First Claim
1. A system for delivering a pulsating supply of fluid to a utilization device, including in combination:
- a source of fluid at a predetermined pressure;
at least first and second utilization devices for receiving fluid on first and second inlets, respectively; and
pulsator means having an inlet coupled with said source of fluid and having at least first and second outlets coupled, respectively, to said first and second inlets of said first and second utilization devices, said pulsator means apportioning fluid in a cyclically varying pattern of pressure from the inlet thereof to each of the first and second outlets thereof such that the total fluid flow through both of said first and second outlets thereof remains substantially constant, and the pressure of fluid at the input to said pulsator means remains substantially constant at said predetermined pressure, while the cyclical flow of fluid through said first outlet increases with a corresponding decrease of the flow of fluid through the second outlet thereof and vice-versa.

Abstract
A system which is particularly useful for use with lavage hand and arm washing machines supplies pulsating jets of water alternately to a first bank of nozzles (for the right hand) and a second bank of nozzles (for the left hand) without causing on/off shocks to be applied to the water supply system. This is accomplished by supplying the water from the water supply (either from a pump and reservoir or a municipal water supply) to the inlet of a rotating distributor located inside a housing. Outlet pipes for the two banks of nozzles are located on diametrically opposite sides of the housing and communicate with the interior. The distributor is designed to increase the flow through one of the outlets while simultaneously decreasing the flow to the other outlet by a corresponding amount, in a manner which produces a sinusoidal pulsation of the water flow out of each of the banks of nozzles. The flow through the first bank of nozzles, however, is 180° out of synchronism with the flow through the other bank of nozzles; so that the total flow from the source of fluid is essentially constant at all times.
