摘要： PROBLEM TO BE SOLVED: To sufficiently show pulsation reduction effect in a low flow rate state without causing enlargement of a variable displacement compressor by simplifying a pulsation reduction device. SOLUTION: A back pressure valve 55 rises during low displacement operation. Rise of the back pressure valve 55 induces a spool valve to be pushed up by a compression spring 54 and to close an opening part 44. Consequently, an intake passage 32 is restricted and transmission of intake pulsation due to self-excited oscillation of an intake valve is prevented. Since a cavity is blocked by the back pressure valve 55 and a circulation hole 52 and the intake passage 32 are under a communication condition when intake pulsation of specific frequency is generated, a damper chamber 58 resonates with the intake pulsation transmitted to the intake passage 32 and Helmholtz resonance effect takes place. As a result, intake pulsation of the specific frequency is attenuated, high intake pulsation reduction effect due to synergy with restriction effect can be provided, and transmission of intake pulsation to an outside can be prevented.

摘要翻译：要解决的问题：通过简化脉动降低装置，不会引起可变排量压缩机的扩大，从而在低流量状态下充分显示脉动降低效果。解决方案：在低排量操作期间，背压阀55上升。背压阀55的上升引起滑阀由压缩弹簧54向上推动并关闭开口部44.因此，进气通道32被限制，并且由于进气的自激振荡而导致进气脉动的传递阀被阻止。由于在产生特定频率的进气脉动时，背压阀55和循环孔52以及进气通道32处于空气通道的情况下，阻尼室58与传递到进气通道32的进气脉动共振和亥姆霍兹共振效应发生。结果，特定频率的进气脉动被衰减，由于与限制效果的协同作用，可以提供高的进气脉动降低效果，并且可以防止进气脉动传递到外部。版权所有（C）2008，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a piston type variable displacement compressor capable of demonstrating excellent performance even at a time of small displacement operation. SOLUTION: Since both of a main suction opening 38 and a sub suction opening 39 are opened at a time of small displacement operation, if a zone where phase of suction stroke of a piston is delayed in relation to an opening stroke of a leading passage corresponding to a cylinder bore of the main suction opening 38 of a suction stroke part 40 of a rotary valve, the sub suction opening 39 is positioned to oppose the leading passage and opens the leading passage in this zone and refrigerant gas flows in a cylinder bore through the sub suction opening 39 and the leading passage. Since the sub suction opening 39 is closed by a spool 33 and only the main suction opening 38 is opened at a time of large displacement operation, gas in the cylinder bore is prevented from flowing in a suction gas side through the sub suction opening 39 in a compression stroke of the piston.
