Problems solved by technology

Therefore, once the problem of leakage of refrigerant and oil from the gap occurs, the required function cannot be fully exhibited.
[0008] In addition, in the case of press-fitting work, there is a possibility of an increase in manufacturing cost due to an increase in man-hours.

Abstract

The present invention provides a multi-stage compression rotary compressor and a compression rotary compressor including a cylinder capable of sealing a spring chamber without performing a press-in operation. The multi-stage compression rotary compressor is provided with first and second rotary compression assemblies (3, 4) driven by a driving assembly (2) in a sealed container. The first and second rotary compression assemblies are provided with: a cylinder (31 , 41); a roller (33, 43) that rotates eccentrically inside the cylinder; a blade (34, 44) that abuts the roller and divides the cylinder into a low-pressure chamber and a high-pressure chamber. The multi-stage compression type The rotary compressor compresses the refrigerant to a high pressure through the first rotary compression assembly and the second rotary compression assembly and discharges the refrigerant. A spring chamber that accommodates a spring (46) is provided in a cylinder that is a part of the second rotary compression assembly. An opening is opened through the upper and lower surfaces of the cylinder that intersects the outer peripheral surface, and the length of the spring chamber is formed to be, Compression is always ensured even when a spring is inserted.

Description

technical field [0001] The present invention relates to a rotary compressor, which is provided with a drive assembly and a single-stage or multi-stage rotary compression assembly driven by the drive assembly in a closed container, and compresses refrigerant through the rotary compression assembly, in particular to a rotary compressor with a multi-stage rotary compressor. A compression-type rotary compressor having a rotary compression assembly and a compression-type rotary compressor provided with a single-stage rotary compression assembly. Background technique [0002] In the past, for compression type rotary compressors, various types of compression type rotary compressors have been proposed and developed, but a compression type rotary compressor having a multi-stage rotary compression assembly, such as a two-stage compression type, is well known. A rotary compressor (for example, refer to Patent Document 1). [0003] like Figure 7 and Figure 8 As shown, the rotary com...
