ABSTRACT:
A proportioning valve for controlling the mixture of two fluids includes a valve body provided with an internal recess, a pair of inlet ports and an outlet spout. A sleeve is inserted in the recess which has deflectable sealing cushions in front of the inlet ports, and a control rod cam which is movable axially and circumferentially for controlling flow is inserted within the sleeve. The control rod cam has a cylindrical portion which forces the sealing cushions into port closing positions, and a tapered region of special contours for controlling relative opening of the inlet ports.
