Valved suction mechanism of a refrigerant compressor

摘要

A compressor has a housing divided by a valve plate into a first chamber and a second chamber. The second chamber has a suction chamber and a discharge chamber. The valve plate includes discharge conduits communicating the first chamber with the discharge chamber and suction conduits communicating the first chamber with the suction chamber. A suction valve member bends to open and close the suction conduits in response to changes in discharge chamber pressure and the resulting pressure difference between the first chamber and the suction chamber. A suction valve control mechanism includes a regulator for regulating opening and closing of the suction valve between a maximum opening position and a minimum opening position in response to changes in discharge chamber pressure. <IMAGE>
