Squeeze Film Damper Valve for Compressor Cylinders

Abstract: 

A compressor plate valve having a valve seat, a valve guard and a valve plate. The valve plate is moveable between the valve guard and valve seat to control fluid passage through passages in the seat, the guard, and the plate. A valve stem passes through the center of the valve guard and is attached to the center of the valve plate. The valve stem provides guidance for the plate valve to ensure parallel motion. In addition to sealing surfaces that oppose passages, the seat and plate have landing surfaces that provide a braking effect when the valve closes through squeeze film action.
