Variable-capacity compressor

A variable displacement compressor comprising:

• a housing including a suction chamber, a crank chamber, a discharge chamber, and a control valve chamber;
• and
• a displacement control valve accommodated in the control valve chamber and fixed to the housing by a circlip, which is engaged with an engagement groove of the housing, wherein
• the displacement control valve includes a valve seat and a valve body arranged in a passage connecting the discharge chamber and the crank chamber or a passage connecting the crank chamber and the suction chamber, the valve body is accommodated in a valve case, an external signal is input to a coil to change an opening degree of the passage between the valve seat and the valve body so that pressure of the crank chamber can be changed, and the coil is protected by a cover;
• vibration generated by impact between the valve seat and the valve body is transmitted through a path extending from the valve seat via the valve case and the circlip to the housing, the variable displacement compressor being characterized in that
• at least one of the circlip, the cover, and the engagement groove includes a cutout or a recess in the path, and a clearance defined by the cutout or the recess forms a means for suppressing transmission of the vibration.
