Abstract:
In a variable displacement compressor comprising a swash plate accommodated in a control pressure chamber, to be rotatable together with a rotary shaft while changing the inclination angle relative to the rotary shaft, and a plurality of pistons arranged around the rotary shaft to be subjected to a reciprocation in accordance with the inclination angle of the swash plate, wherein the inner pressure of the control pressure chamber is controlled to change the inclination angle of the swash plate,a structure for controlling a capacity in the variable displacement compressor comprisinga maximum inclination-angle restriction body rotatable together with the rotary shaft, for defining the maximum inclination angle of the swash plate, anda wear-resistant piece attached to at least one of the swash plate and the maximum inclination angle-restriction body,wherein the maximum inclination angle of the swash plate is restricted by the maximum inclination angle-restriction body via the wear-resistant piece, and a mating member is arranged to be in contact with the wear-resistant piece when the swash plate is in a maximum inclination-angle position, and the mating member and the wear-resistant piece are made of wear-resistant material, and wherein the wear-resistant piece is attached to a position contained in a discharge stroke region on the swash plate around the rotary shaft as seen in the axial direction of the rotary shaft.
