Abstract
A delivery valve device for a refrigerant compressor. The delivery valve device include a valve plate with the delivery passage closed by a delivery valve fixed at one end to the valve plate and pressed against this valve plate at its free end by a spring. A valve stop is fixed with the delivery valve and the spring to the valve plate to clamp one end of the delivery valve and of the spring onto the valve plate using rivets. The sliding contact of the free end of the delivery valve on the plate avoids valve bounce and flutter. Such a delivery valve may reduce the noise level in refrigeration compressors.
