摘要： PROBLEM TO BE SOLVED: To provide a capacity control mechanism capable of shortening a time taken until a discharge capacity is increased after the start of a variable displacement compressor and ensuring a refrigerant discharge flow rate suitable for lubrication and capacity control. SOLUTION: A first control valve 32, a second control valve 46, a third control valve 73, and a fourth control valve 47 are assembled into a rear housing 13. A valve element 49 of the second control valve 46 partitions a back pressure chamber 52 in a valve housing 48. When the first control valve 32 is in an opened state, the pressure of a discharge chamber 132 spreads to the back pressure chamber 52 and the second control valve 46 is closed. When the first control valve 32 is closed, the second control valve 46 is opened. The third control valve 73 is shifted to an opened state in a process in which a difference between the pressure of a control pressure chamber 121 and the pressure of a suction chamber 131 is increased from a closed state. The fourth control valve 47 is shifted to an opened state from a closed state in a process in which a difference in pressure is further increased. COPYRIGHT: (C)2006,JPO&NCIPI
摘要翻译：要解决的问题：提供一种容量控制机构，其能够缩短在可变排量压缩机启动之后直到放电容量增加所花费的时间，并确保适合于润滑和容量控制的制冷剂排出流量。解决方案：第一控制阀32，第二控制阀46，第三控制阀73和第四控制阀47组装到后壳体13中。第二控制阀46的阀元件49将后部当第一控制阀32处于打开状态时，排出室132的压力扩展到背压室52，第二控制阀46关闭。当第一控制阀32关闭时，第二控制阀46打开。在控制压力室121的压力与吸入室131的压力之间的差从关闭状态增加的过程中，第三控制阀73移动到打开状态。在压力差进一步增加的过程中，第四控制阀47从关闭状态转移到打开状态。版权所有（C）2006，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To provide a capacity control mechanism capable of shortening a time taken until a discharge capacity is increased after the start of a variable displacement compressor and improving operation efficiency when operating by a minimum capacity. SOLUTION: A first control valve 32, a second control valve 46, and a third control valve 47 are assembled into a rear housing 13. A valve element 49 of the second control valve 46 partitions a back pressure chamber 52 in a valve housing 48. When the first control valve 32 is in an opened state, the pressure of a discharge chamber 132 spreads to the back pressure chamber 52, and the second control valve 46 is closed. When the first control valve 32 is closed, the second control valve 46 is opened. The third control valve 47 is shifted to an opened state in a process in which a difference between the pressure of a control pressure chamber 121 and the pressure of a suction chamber 131 is increased from the closed state.
