<p><P>PROBLEM TO BE SOLVED: To provide a variable displacement compressor capable of restraining leakage of refrigerant gas from a supply passage, and capable of preventing the deterioration in a lubricating state of a shaft seal member. <P>SOLUTION: This variable displacement compressor 10 has a thrust receiving mechanism 70 regulating the movement of a rotary shaft 16 in the direction turning to the rear end part side of the rotary shaft 16 from the control pressure chamber 15 side by a spring load of a disc spring 73. The thrust receiving mechanism 70 partitions a supply space S1 between a rear end surface 16A in the rotary shaft 16 and a valve port forming body 13 opposed to the rear end surface 16A. The thrust receiving mechanism 70 is constituted for restraining leakage of the refrigerant gas from the supply space S1 by pressure contact with the rear end surface 16A of the rotary shaft 16 and the valve port forming body 13 by the spring load of the disc spring 73. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
