摘要:
The present invention relates to a compressor, wherein a rotary shaft 140 having a swash plate 144 coupled thereto is used to linearly reciprocate a piston 150 in a cylinder bore 134 formed in front and rear cylinder blocks 130 and 130′. The rotary shaft 140 has a flow channel 142 formed therein and inlets 142a formed to communicate with the flow channel 142. A hub 146 is formed in the swash plate 144, and a shaft hole 146a, through which the rotary shaft 140 passes, is formed in the center of the hub 146. Communication holes 146b are formed in the hub 146 to communicate with the inlets 142a of the flow channel 142. First races 148a are coupled to the hub 146. A rotary shaft hole 148d is formed in the first race 148a, which has a thickness greater in its outer peripheral portion than its inner peripheral portion. According to the present invention configured as above, the communication holes 146b are concavely formed in surfaces where inlets of the shaft hole 146a of the hub 146 are provided, so that the communication holes 146b can be formed together with the hub. Thus, there is an advantage in that the compressor can be easily manufactured. Also, the first race 148a has a thickness greater in its outer peripheral portion than its inner peripheral portion. Accordingly, there is an effect in that the strength of the first race 148a can be reinforced while keeping its damping effect, thereby improving durability of the swash plate type compressor.

A swash plate type compressor includes a front head portion having a suction chamber and a discharge chamber sectioned by a partition wall formed on an inner surface of the front head portion, and having at least one upper discharge guide groove and at least one lower discharge guide groove formed in an upper portion and a lower portion of the discharge chamber, respectively, a rear head portion having a suction chamber and a discharge chamber sectioned by a partition wall formed on an inner surface of the rear head portion, and having at least one upper discharge guide groove and at least one lower discharge guide groove formed in an upper portion and a lower portion of the discharge chamber, respectively, to correspond to the upper and lower discharge guide groove of the front head portion, a cylinder installed between the front and rear head portions or inside the front and rear head portions and having a plurality of bores installed such that pistons are capable of sliding therein, at least one upper discharge passageway and at least one lower discharge passageway for connecting the upper and lower discharge guide grooves of the front and rear head portions, respectively, a drive shaft installed to penetrate the cylinder and rotated by a driving source, and a swash plate installed at the driving shaft to be inclined and having the pistons installed at an end portion of the swash plate. Thus, in the swash plate type compressor, the compressed refrigerant can be quickly discharged with less resistance so that, when the liquid refrigerant is sucked, compression noise can be reduced.
