Abstract
A discharge system for rolling piston rotary compressor, including a hermetic housing a cylinder block having a rolling piston assembled on an eccentric shaft supported by a pair of bearings assembled at opposed sides of the cylinder block. The first of said bearings is innerly shaped as a discharge muffler chamber open to the end face of said bearing which is turned to the cylinder block and closed by a valve plate directed seated against the end adjacent face of the cylinder block, said valve plate having an axial eccentrical discharge port communicating the interior of the cylinder block with a recess bottom having a blade discharge valve seat turned to the interior of the portion in the discharge muffler chamber. Such arrangement allows the valve plate to simultaneously work as a discharge muffler chamber cover and as an end wall of the cylinder block, and such arrangement can further be sized to have a minimum thickness which will only be enough to incoporate the blade valve housing recess and a small axial extension of the discharge port.
