Abstract

<P>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. <P>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. <P>COPYRIGHT: (C)2008,JPO&INPIT
