ABSTRACT:
A three way slide valve includes a rectangular valve slide fitted into a housing formed of two halves having mating flat surfaces. Each housing half is recessed to provide a chamber for the valve slide and also a spring chamber which restrains both ends of a double acting return spring. One end of the return spring engages one end of the valve slide and the other part of the spring engages a loop on the valve slide for return to center action. Ports in the housing halves are provided with shear seals in engagement with the valve slide.
