摘要:
A swash plate compressor includes a drive shaft rotated by a driving source, a swash plate fixedly installed at the drive shaft, a piston reciprocated by the swash plate, a cylinder bore in which the piston is slidingly installed for guiding reciprocation of the piston, a thrust bearing supporting a thrust force generated by the swash plate and the drive shaft, a race having a radial protrusion for preventing rotation at an outer circumference, and a cylinder block having a protrusion fixing element for preventing rotation of the race by fixing the protrusion of the race. Thus, abrasion due to rotational friction between the flat surface of the race and the thrust surface of the cylinder block can be prevented. Also, since generation of a gap between the cylinder block and the swash plate because of the abrasion of the flat surface of the race and the thrust surface of the cylinder block is prevented, noise in the compressor, damage to the thrust bearing, and damage to the neighboring member is prevented. Further, when incorrect assembly is performed, the protrusions interfere with the piston so that incorrect assembly can be easily detected and correct assembly can be easily performed.

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.

The present invention relates to a compressor used in an air conditioner of a vehicle. In the present invention, an oil separation chamber and a discharge chamber are formed in one side of a discharge chamber of a compressor, a cylindrical oil separation conduit is formed between the oil separation chamber and the discharge chamber. At the same time, one discharge passage is formed such that refrigerant supplied from the front and rear discharge chambers is collected and oil is separated from the refrigerant, so that the oil is separated from the compressed refrigerant and returns to a swash plate chamber, thereby improving lubricity in the swash plate chamber.

A reciprocating piston type compressor comprises a cylinder block assembly, a drive shaft rotating together with a swash plate, a plurality of cylinder bores, a plurality of reciprocating pistons fitted within the cylinder bores, front and rear valve plates, front and rear suction and discharge valves, and front and rear housings. The front housing has a suction chamber for a refrigerant gas to be compressed and a discharge chamber for the compressed refrigerant gas in response to reciprocation of the pistons. The rear housing has a suction chamber for a refrigerant gas to be compressed, a discharge chamber for the compressed refrigerant gas, and an outlet chamber for delivering the compressed refrigerant gas carried therein from the discharge chamber of the front housing via a discharge passageway formed in the cylinder block assembly toward an external climate control system. A discharge conduit is formed in the discharge chamber of the rear housing to be orthogonally communicated with the outlet chamber. A sum of volumes of the discharge chamber of the front housing and the discharge passageway is the same as a sum of volumes of the discharge chamber of the rear housing and the discharge conduit. The discharge conduit extends to about half of the distance between a point on an interior surface of an inner wall of the rear hosusing and an opposite point on the interior surface of the inner wall.
