Abstract

The invention relates to a rotary compression chamber, comprising: a driving motor and a rotating shaft, the driving motor is arranged inside the housing, and the rotating shaft is combined with the driving motor to transmit rotational force; a first cylinder and a second cylinder The cylinder has a compression space formed in the circular center of the opening; the first roller and the second roller revolve in the compression space; the first vane and the second vane divide the compression space of each cylinder into suction chamber and compression chamber; a main bearing coupled to the upper portion of the first cylinder and a sub-bearing coupled to the lower portion of the second cylinder; and an intermediate plate disposed on the main Between the bearing and the sub-bearing, the first cylinder and the second cylinder are separated; the middle plate is formed with an oil flow path formed from one side toward the inside, passing along the oil flow path The moving oil undergoes heat exchange.

Description

technical field [0001] The present invention relates to a hermetic compressor, and particularly to a rotary compressor capable of lowering the temperature of a compression unit. Background technique [0002] As a vapor compression refrigeration cycle device suitable for such as a refrigerator or an air conditioner, a compressor can be divided into a rotary type and a reciprocating type according to the way the compressor compresses the refrigerant. [0003] The rotary compressor is a way to make the volume of the compression space variable by rolling the piston (hereinafter referred to as the roller) in the cylinder to rotate or revolve, and the reciprocating compressor is to make the compression space by the reciprocating motion of the roller in the cylinder. variable volume. [0004] As a rotary compressor, there is a rotary compressor that compresses refrigerant using the rotational force of a transmission unit. [0005] In recent years, gradually miniaturizing rotary c...
