    摘要: In a scroll type compressor, when the operation of the compressor is stopped, compression chambers, for compressing a fluid, and a suction chamber are communicated with each other through bypass holes, and a spool valve to open and close the holes, so that the pressure in the compression chambers are lowered and the occurrence of a shock caused by a sharp increase in the load is prevented at the next start. Since the discharge pressure to drive the spool valve is introduced from a position upstream of the discharge valve, pressure is quickly lowered when the compressor stops, so that the spool valve can be quickly opened. Therefore, even when the compressor is frequently started and stopped, the occurrence of a shock can be positively prevented when the compressor starts.

    摘要: A swash plate type variable capacity compressor having rotary valves that rotate together on a rotating shaft. The rotary valves are arranged on the shaft in such a manner that, upon one complete rotation, the rotary valves are connected, in sequential manner, for respective rotating angles, with circumferentially spaced piston chambers via respective intake passageways on the rotary valves. The arrangement between the intake passageways and the piston chamber changes in accordance with the axial position of the rotary valves on the shaft. Control of the rotating angle varies the effective volume of the piston chambers, thereby continuously varying the compressor capacity.
