A compressor is provided to form an auxiliary inlet at a hub side plane of a swash plate to secure a refrigerant suction path to minimize refrigerant suction resistance and improve lubrication action to thrust bearing, thereby improving performance of the compressor. A driving shaft(150) has a passage(151) for moving refrigerant sucked into a compressor, to cylinder bores, wherein an inlet(152) is formed at the passage connecting with a swash plate chamber, and a pair of outlets are formed oppositely to each other. Cylinder blocks have the driving shaft installed at shaft support holes rotatably, and have suction paths connecting the shaft support holes with the cylinder bores to suck the refrigerant into each cylinder bore. A plurality of pistons are mounted at an outer periphery of a swash plate(160) by interposing a shoe, and interact with rotation of the swash plate to reciprocate in the cylinder bores. A thrust bearing(180) is installed between the swash plate and the cylinder blocks to be assembled with the driving shaft. Front and rear housings are assembled with both sides of the cylinder blocks and have discharge chambers inside. Valve units are interposed between the cylinder blocks and the front and rear housings. An auxiliary inlet(154) is formed at the swash plate, having one end contacting with the thrust bearing and the other end connected with the inlet of the passage.
