Abstract
A compressor includes a cylinder crankcase defining a cylinder which is closed by a valve plate provided with at least one discharge orifice associated with a discharge valve and defining, with the cylinder, a compression chamber; a cylinder cap seated against the valve plate and inside which is defined a discharge chamber. A portion of the cylinder cap is dimensioned to receive the entire flow of refrigerant gas released through the discharge orifice and accelerate said gas flow so as to produce an instantaneous reduction in the pressure gradient between the upstream and downstream sides of the discharge valve, in the moment the latter opens.
