IPC: F04B27/14
Filed: 2004-04-22
Abstract: <P>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.  <P>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.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
