ABSTRACT:
A compressor having an inlet valve which includes a valve housing and a control tube having a portion adapted to be in communication with a source of fluid. A piston is normally spring biased away from a valve element which is adapted to be alternately placed in sealing contact with a valve seat and withdrawn from such contact. The piston and valve element are movably mounted on the exterior of the control tube. Orifices in the control tube are adapted to control movement of the piston against the bias of the spring and also to provide a modulating influence as well as additional pressure balancing characteristics. The valve is also adapted to function as a bypass valve, a check valve and a blowdown function.
