Problems solved by technology

[0010] However, in the compressor according to another embodiment of this convention, although the coating layer is formed on the surface of the thrust plate 52, the oil supply between the thrust plate 52 and the rotary shaft 50 causes the The coating peels off, and as a result there is a problem that the thrust plate 52 is damaged
[0011] In addition, in the conventional compressor disclosed in Korean Registered Patent Publication No. 10-1181157, as the chamber housing the thrust bearings 153a, 154, 153b or the thrust plate 52 is formed in a cylindrical shape, there is a problem that it is difficult to take it out from the mold. Problems with the cylinder 10, 110 (demolding) with the chamber formed

Abstract

The present invention relates to a compressor comprising: a casing; a rotational shaft rotatably mounted in the casing; a compression mechanism connected to the rotational shaft and compressing a refrigerant; a thrust plate for supporting the front-end surface of the rotational shaft; a chamber for receiving the thrust plate; and a slit for guiding oil to the chamber, wherein one portion of the slit is formed so as to face a contacting portion between the rotational shaft and the thrust plate so as to supply oil to the portion between the rotational shaft and the thrust plate, and thus damage to the thrust plate, which supports the rotational shaft, may be prevented. In addition, the chamber is formed so as to extend, while the inner diameter thereof gradually increases, up to the front-end surface of a cylinder block, thereby enabling the cylinder block to be easily ejected from a mold.

Description

technical field [0001] The present invention relates to a compressor, and more particularly, to a compressor capable of preventing damage to a thrust plate that supports a rotating shaft that transmits rotational force from a drive source to a compression mechanism. Background technique [0002] Generally, an air conditioner (Air Conditioning; A / C) for cooling and heating a room is installed in an automobile. Such an air conditioner is configured as a refrigeration system, which includes a compressor that compresses a low-temperature and low-pressure gas-phase refrigerant introduced from an evaporator into a high-temperature and high-pressure gas-phase refrigerant and sends it to a condenser. [0003] The compressor includes a reciprocating type that compresses refrigerant along with the reciprocating motion of a piston, and a rotary type that compresses refrigerant while rotating. [0004] In the reciprocating type, there are a crankshaft type that uses a crankshaft to tra...
