Swash plate type variable displacement compressor

A swash plate type variable displacement compressor comprising:

• a housing having a suction chamber, a discharge chamber, and a swash plate chamber;
• a cylinder block having therein a plurality of cylinder bores;
• a drive shaft rotatably supported in the housing;
• a swash plate disposed in the swash plate chamber and rotatable with the drive shaft;
• a link provided between the drive shaft and the swash plate that permits a change in an inclination angle of the swash plate to an imaginary plane extending perpendicularly to an axis of the drive shaft;
• a plurality of pistons reciprocally movably received in the respective cylinder bores;
• a converter that converts the rotation of the swash plate to the reciprocal motion of the pistons with a stroke length that is variable according to the inclination angle of swash plate;
• an actuator disposed in the swash plate chamber to change the inclination angle;
• and
• a controller that controls the actuator,
• wherein the actuator includes a partitioning member mounted on the drive shaft, a moving member connected to the swash plate, mounted on the drive shaft, and movable along the axis of the drive shaft, and a pressure control chamber provided between the partitioning member and the moving member, and wherein the actuator is configured in such a way that the moving member is moved when refrigerant in the discharge chamber is introduced into the pressure control chamber,
• wherein a support member is fitted on the drive shaft, wherein contact of the support member with the moving member determines a maximum value of the inclination angle,
• wherein a thrust bearing is provided between the cylinder block and the drive shaft, the thrust bearing is further provided between the support member and the cylinder block to support a thrust force through the support member,
• wherein the support member has a cylindrical portion that is fitted on the drive shaft, wherein a position of the cylindrical portion is adjustable along the axis of the drive shaft, and
• wherein the cylindrical portion projects beyond one end of the drive shaft.
