Abstract

This is a kind of air discharging structure of twin rotating compressor. It includes the first and second air cylinders, which absorb and compress refrigerants; intermediate bearing separating the inner space of the two air cylinders; main bearing and assistant bearing respectively setting at upper and lower sides of the air cylinders at both sides. They not only seal the inner space of two air cylinders, but also support the rotating shaft, which transfers the driving force of driving electric engine; many rotating pistons, which connect to the rotating shaft and carries out gyration. They compress refrigerants with each throttle valves; the first discharging passage, which is in the main bearing and is used for discharging the refrigerants compressed by the first air cylinder; the second discharging passage, which forms by connecting the second air cylinder, intermediate bearing, the first air cylinder and the said main bearing. This invention decreases the number of mufflers and reduces the material cost.

Description

technical field

[0001] The invention relates to a compound rotary compressor, in particular to a gas discharge structure of the compound rotary compressor which can flexibly induce the refrigerant discharged from each compression part. Background technique

[0002] Generally, a compressor refers to a device that converts mechanical energy into compression energy of a compressible fluid, and can generally be classified into a reciprocating type, a scroll type, a center type, and a vane type. Rotary compressors are mainly used in air coordinating equipment such as air conditioners. Recently, in order to reduce eccentric loads, a multi-type rotary compressor has been proposed that has a plurality of compressing parts by symmetrically forming the centrifugal part of the rotating shaft.

[0003] figure 1 It is a sectional view of an embodiment of an existing compound rotary compressor.

[0004] As shown in the figure, the existing compound rotary compressor includes: a casing 1...
