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.

Variable displacement swash plate type compressor

Provided is a variable displacement swash plate type compressor including a cylinder block having a plurality of cylinder bores, a drive shaft rotatably supported by the cylinder block, a lug plate fixedly installed at the drive shaft, a swash plate rotated by the lug plate to vary its inclination angle, and pistons reciprocally accommodated in the cylinder bores depending on rotation of the swash plate, the compressor including a projection projecting from the lug plate toward the swash plate and disposed only behind the rotational direction of the drive shaft, a slope formed on the rear part of the lug plate at one side of the projection, an arm projecting from the swash plate toward the lug plate, a first guide coupled to the arm in front of the rotational direction of the drive shaft to move along the slope in a contact manner, and a second guide coupled to the arm adjacent to the projection to move along the slope in a contact manner.
