Abstract
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.
