    • 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.
    • 在涡旋式压缩机中,当压缩机的运转停止时,用于压缩流体的压缩室和吸入室通过旁通孔彼此连通,并且用于打开和关闭孔的滑阀, 压缩室中的压力降低,并且在下次起动时防止由负载急剧增加引起的冲击的发生。 由于驱动滑阀的排出压力从排出阀的上游侧被引入,所以当压缩机停止时,压力迅速降低,从而能够快速地打开滑阀。 因此,即使当压缩机频繁地启动和停止时,当压缩机启动时也能够有效地防止冲击的发生。
