Contracting machine, arranges intermediate throughholes 11 to connect the upper end oilhole 42 of compressor inside crankshaft 37, base plate in oil separating device 36 base plate 10
10 upper end is provided with the cylindrical sidewall 20 that upper end open area is less than the area of lower end port, and in cylindrical sidewall 20 and base plate
10 junction or in cylindrical sidewall 20 arrange oil extraction portion.
During use, this oil separating device 36 is fixed on the upper end of rotor 44, after compressor operation, rotor 44 drives oil
From device 36 high-speed rotation.On the one hand, the freezing oil that the oilhole 42 from bent axle 37 upper end is discharged, enters oil separating device 36, oil
Segregation apparatuss 36 pass through centrifugal action, most of freezing oil are discharged to the outside of oil separating device 36 by oil extraction portion, significantly subtract
Lack the oil mass discharged from exhaustor 39；On the other hand, positioned at compressor epicoele 38 and flow to the gas mixture of exhaustor 39,
Due to stop and the centrifugal action of the cylindrical sidewall 20 of oil separating device 36, part gas mixture is discharged to oil by oil extraction portion
The outside of segregation apparatuss 36, decreases the oil mass that this part gas mixture is directly entered exhaustor 39.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for the skill of this area
For art personnel, the present invention can have various modifications and variations.All within the spirit and principles in the present invention, made any repair
