ABSTRACT:
A valve system for mixing two pressurized liquids, A and B, in varying proportions ranging from 0% liquid A, 100% liquid B to 100% liquid A, 0% liquid B comprises two liquid inlet passages, a mixture outlet passage, and a spool valve disposed therebetween for directing the desired proportions of liquid to the outlet passage. The liquid proportions are adjusted by rotating the spool valve between two predetermined stops thereby allowing incoming fluids to flow at different rates into offset bores extending through the spool valve. Such a valve system is useful in vehicle and aircraft cleaning systems wherein one liquid comprises a soap solution and the other comprises water.
