Variable Capacity Swash Plate Type Compressor

Abstract

The present invention relates to a variable capacity swash plate type compressor, which has a stopper protruding from the inner surface of a hub and being in contact with a sleeve when a swash plate is at the maximum inclination angle to shorten a stroke distance of the stopper for supporting the maximum inclination angle of the swash plate, thereby reducing a hitting noise when the stopper is moved at the maximum inclination angle and when an air conditioner is turned off.

1 - 3 . (canceled) 
   
   
       4 . A variable capacity swash plate type compressor, which includes:
 a cylinder block having a plurality of cylinder bores therein;   a front housing mounted on the front of the cylinder block and having a crank chamber therein, and a rear housing mounted on the rear of the cylinder block and having a suction chamber and a discharge chamber therein;   a driving shaft rotatably mounted on the cylinder block and the front housing;   a rotor combined to the driving shaft and rotating together with the driving shaft inside the crank chamber;   a swash plate having a hub movably connected to a hinge arm of the rotor and a swash plate board combined to the hub, the hub being rotatably combined to a sleeve which is slidably combined to the driving shaft, the swash plate varying its inclination angle in correspondence to a pressure change of the crank chamber; and   a spring mounted on the driving shaft located between the rotor and the swash plate for returning the swash plate to the initial position,   wherein maximum inclination angle supporting means is provided between the hub and the sleeve.   
   
   
       5 . The variable capacity swash plate type compressor according to  claim 4 , wherein the maximum inclination angle supporting means is provided with a stopper protruding from the inner surface of the hub or the outer surface of the sleeve, whereby the stopper is in contact with the outer surface of the sleeve or the inner surface of the hub is at the maximum inclination angle. 
   
   
       6 . The variable capacity swash plate type compressor according to  claim 5 , wherein the stopper is formed on a connection line (LC) passing a position (P 1 ) of the swash plate corresponding with the center of the cylinder bore, which is in the maximum compression stroke state, and a center (P 2 ) of the driving shaft.
