Abstract
A pinch tube proportioning valve includes support structure defining an elongated valve cavity having a longitudinal axis and a pair of spaced resilient valve tubes disposed in the cavity and respectively providing communication between two fluid supply conduits and a fluid outlet. A control cam cartridge is receivable in the valve cavity between the valve tubes. The cartridge includes a cylindrical housing closed at one end and carrying at its closed end a guide pin extending axially up through the housing and receivable in an axial bore in an elongated tapered cam member, which is telescopically received in the open end of the housing. Diametrically opposed openings are formed in the side wall of the housing for receiving the valve tubes to permit engagement thereof by the cam member, which is axially and rotatably movable to control proportioning and flow rate through the valve tubes.
