Abstract
A hermetic refrigeration compressor has a flat valve plate closing off a cylinder bore. The valve plate has an elongated recess on the outer side around the discharge port and a discharge valve assembly, comprising a flat reed valve and backing spring, fits within the recess beneath an overlying valve stop which engages the bottom of the recess at each end. The recess, the reed valve, the backing spring, and the valve stop are so configured that they can be assembled only in the correct configuration. The valve stop is held in place by an arcuate retaining spring having ends engaging notches in the valve plate and a projecting boss on a cylinder head defining a discharge valve plenum engages the retaining spring to press the spring and the valve plate into position within the recess to retain all of the parts in operating position.
