摘要： Provides is a variable displacement swash plate type compressor comprising a drive shaft, a lug plate fixedly installed at one side of the drive shaft, a swash plate dispose at another side of the drive shaft and rotated by the lug plate to vary a tilt angle thereof, a sleeve reciprocally moving along the drive shaft to let the swash plate rotate, and a spring supported between the sleeve and the lug plate, characterized in that the variable displacement swash plate type compressor comprises a restriction ring installed around the drive shaft between the lug plate and the sleeve to contact with the swash plate at a maximum tilt angle of the swash plate, wherein an end of the restriction ring is contacted with the lug plate and another end of the restriction ring is supported by the spring. Thus, since the direct contact between the swash plate and the lug plate is prevented, when the swash plate reaches at the maximum tilt angle, it is possible to reduce the noise and the wear remarkably.

摘要： Provided is a variable displacement compressor comprising a cylinder block having a plurality of cylinder bores, housing, a drive shaft rotatably supported by the cylinder block, a lug plate, a swash plate being rotated by the lug plate to vary a tilt angle thereof, a sleeve reciprocally moving along the drive shaft, an addition discharge passage for fluid communication between the swash plate chamber and the suction chamber, characterized in that the variable displacement compressor comprises: a communication hole being a part of the addition discharge passage and formed in the drive shaft in its longitudinal direction; and a lateral communication passage formed at the lateral side of the drive shaft to be connected to the communication hole such that the lateral communication passage is opened and closed by reciprocal movement of the sleeve. Therefore, even though the swash plate is at position of the maximum tilt angle, the temperature of the swash plate chamber is prevented from rising by making a smooth refrigerant flow from the swash plate chamber to the suction chamber, thereby maintaining higher lubrication ability.
