<p>The compressor comprises: a cylinder crankcase (1) defining a cylinder (2) which is closed by a valve plate (3) provided with at least one discharge orifice (3a) associated with a discharge valve (4) and defining, with the cylinder (2), a compression chamber (C); a cylinder cap (10) seated against the valve plate (3) and inside which is defined a discharge chamber (11). The system comprises an accelerating means (AM) mounted in the interior of the discharge chamber (11) and secured to at least one of the parts of cylinder cap (10) and valve plate (3), in order to receive the entire flow of refrigerant gas released through the discharge orifice (3a), accelerating said gas flow and producing an instantaneous reduction in the pressure gradient between the upstream and downstream sides of the discharge valve (4), in the moment the latter opens.</p> |
