Having skewed slot venting one's pent-up feelings, described cylinder bottom has blade groove.
Preferably, described blade groove is vertical-shaped strip channel-shaped, and blade groove is arranged on the cylinder inner wall of cylinder-bore upper end, blade groove
Inside being provided with the blade of compressor pumping, described skewed slot venting one's pent-up feelings is positioned at the side of blade groove.
Preferably, the circular in cross-section of described skewed slot venting one's pent-up feelings, the radius of curvature of the inner face of described skewed slot venting one's pent-up feelings be 8.4mm～
8.6mm。
Preferably, between the line at described cylinder-bore center, the line at blade groove center and cylinder-bore center, skewed slot center of feeling elated and exultant
Angle be set to 13.4 °～13.6 °.
Preferably, the upper port of described skewed slot venting one's pent-up feelings is positioned at the upper surface of cylinder, and place, described skewed slot upper end venting one's pent-up feelings plane is with venting one's pent-up feelings
Vertical dimension between the plane of place, skewed slot lower end is 4.2mm～4.4mm.
Preferably, described skewed slot venting one's pent-up feelings tilts to extend to cylinder inner wall, and the angle of inclination that described skewed slot venting one's pent-up feelings tilts after extending is arranged
It it is 45 °.
The beneficial effects of the utility model are:
The above-mentioned Rotary Compressor with Novel air cylinder, mouth venting one's pent-up feelings and resonant cavity to cylinder improved, and well resonant cavity goes
Removing, tell outlet portion for cylinder, in mouth venting one's pent-up feelings prolongs cylinder, the warp-wise cylinder center of circle is moved, and draws most preferably by calculating and verifying
Interior shifting amount, this improved procedure can not only ensure that cylinder operates more efficiently, and the only one of which of cylinder inside
Mouth venting one's pent-up feelings, processing novel air cylinder structure the most simpler saving operation.This Novel air cylinder can effectively reduce the clearance of pumping to be held
Long-pending, improve the efficiency that Rotary Compressor is overall.
