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.

- a valve seat having a first set of passage channels;
- a valve guard having a second set of passage channels;
- a valve plate having a third set of passage channels, the valve plate being disposed between the valve seat and the valve guard and moveable between them to control the passage of fluid through the valve;
- a valve stem attached at a first end to the center of the valve plate and passing through the center of the valve guard;
- wherein the valve seat, valve guard and the valve plate have sealing surfaces that oppose passage channels;
- and wherein the valve seat and valve plate have landing surfaces that oppose other landing surfaces and do not oppose passage channels.
