Variable displacement swash plate type compressor

A variable displacement swash plate type compressor comprising:

• a housing in which a suction chamber, a discharge chamber, a swash plate chamber, and at least one cylinder bore are formed;
• a drive shaft extending along a drive axis and rotatably supported in the housing;
• a swash plate rotatable in the swash plate chamber along with rotation of the drive shaft;
• a link mechanism that is provided between the drive shaft and the swash plate and permits change of an inclination angle of the swash plate in a direction perpendicular to the drive axis of the drive shaft;
• a piston reciprocally accommodated in the cylinder bore;
• a conversion mechanism that reciprocates the piston in the cylinder bore along with rotation of the swash plate at a stroke corresponding to the inclination angle;
• an actuator that is disposed in the swash plate chamber and capable of changing the inclination angle;
• and
• a control mechanism that controls the actuator, wherein
• the suction chamber and the swash plate chamber communicate with each other,
• the actuator includes a partition body provided on the drive shaft, a movable body that is coupled to the swash plate via a coupling mechanism and movable with respect to the partition body along the drive axis of the drive shaft, and a control pressure chamber that is defined by the partition body and the movable body and moves the movable body by introducing a refrigerant from the discharge chamber,
• the movable body is disposed so as to increase the inclination angle by pulling the swash plate when pressure in the control pressure chamber increases,
• the link mechanism includes a coupling portion that is coupled to the swash plate, and
• the coupling mechanism is disposed on an opposite side of the coupling portion with respect to the drive shaft and includes a first arm and a second arm provided at the movable body across the drive axis.
