130, lower flange 140, valve block component 160 and baffle 150.Upper flange 110 is separately mounted to the two of cylinder 130 with lower flange 140
End, shaft 120 are mounted in cylinder 130, and one end of shaft 120 passes through upper flange 110.Slide plate 121 is provided in shaft 120
With sliding vane groove 122, slide plate 121 is mounted in sliding vane groove 122, and the quantity of slide plate 121 can be one.Certainly, slide plate 121
Quantity may be two and two or more, correspondingly, the quantity of sliding vane groove 122 is also two and two or more.In this implementation
In example, the quantity of slide plate 121 is three, and the quantity of corresponding sliding vane groove 122 is also three.Radial direction along cylinder 130 is set
It is equipped with gas vent 131, baffle 150 is arranged in the side of the outgassing direction of gas vent 131.Increase gear at the exhaust of cylinder 130
Plate 150 so that baffle 150 can just cover gas vent 131, and high pressure refrigerant touches baffle 150 after being flowed out in cylinder 130
Change flow direction.
