The beneficial effects of the present invention are: annular retaining ring is arranged in the present invention in shell, it is discharged from fixed scroll exhaust outlet
High pressure gaseous refrigerant, which first flows through the discharge chamber of fixed scroll and annular retaining ring composition, using quiet
Gap between scroll plate and annular retaining ring, gas are collided in narrow gap location, and lubricating oil is from high-pressure gaseous refrigerant
Separate, under the effect of gravity, liquid lubricant flows into housing bottom, and gaseous coolant is discharged to exhaust passage, gaseous coolant after
Continue and collided in exhaust passage, carry out secondary oil gas separation, last gaseous coolant exports row from the high pressure gas on shell wall side
It is put into outside shell.The present invention with simple process, does not increase the spy of processing compared with the prior art processes exhaust pipe in shell
Point, and do not increase components, it does not need that oil pipe additionally is installed, so that it may achieve the purpose that Oil-gas Separation.
Preferably, step surface is set on annular retaining ring, it, can be with when by gap between fixed scroll and annular retaining ring
Increase the collision area of gas and annular retaining ring, improves oil gas separation.
Preferably, annular step surface, which slopes inwardly, is arranged, can be corresponding with annular convex platform on fixed scroll, makes gas more
Pass through in gap between good slave fixed scroll and annular retaining ring.
Preferably, baffle is set in annular retaining ring, that is, in the discharge chamber of fixed scroll and annular retaining ring composition
Baffle is set, the flowing of high temperature and high pressure gas is stopped, gas carries out multiple impacts with baffle in flowing, improves oil
Gas separating effect.
Preferably, baffle is gradually increased from annular retaining ring center to annular retaining ring inside wall height, and neither influence gas is whole
Body flowing, and the collision area of gas is increased, further increase oil gas separation.
Preferably, annular retaining ring and baffle are integrally formed in shell, manufacture shell convenient for overall processing.
