ABSTRACT:
The present invention is directed to a three way valve having particular utility as an air control valve and providing an enhanced duty cycle. A characterizing feature of the valve resides in the construction and arrangement whereby the valve plunger is, in all conditions of operation, slidably guided for precise axial movement in a bore whereby any tendency of the plunger to tilt or cant, with accompanying damage or scarring of internal elements of the valve structure, is positively prevented.
