Abstract

PURPOSE: To enable volume control without increasing power loss by communicating a compression chamber with a suction chamber through a control valve and by performing such a volume control system as the compression chamber may be by passed to the suction chamber.
CONSTITUTION: When a rotating scroll member 2 makes a rotating motion as illustrated in the figure, compression chambers 5(5a and 5b) are formed. The compression chambers 5 consist of a fixed scroll member 1 and a rotating scroll member 2. When the control valves 18 in the figure (18) are opened and bypass bores provided in the end member 1a of the fixed scroll member are communicated to a suction nozzle 1C through the bypass piping and the control valve 18, the compression chambers are not formed. Only when the rotating scroll member 2 is further rotated clockwise and the bypass bores provided in the end member 1a of the fixed scroll are closed, the compressure chambers 5(5a and 5b) are formed. With this constrution, volume control can be performed without increasing power loss(useless power).
