Abstract

The invention discloses a rotary compressor, which comprises a shell, a motor, a compressing mechanism and an oil rate adjusting valve, wherein the compressing mechanism comprises a crankshaft; an opened central oil hole and a lateral oil hole are formed in one end away from the motor, of the crankshaft, the lateral oil hole is communicated with the central oil hole and penetrates through the side wall of the crankshaft; the oil rate adjusting valve is arranged in the central oil hole and comprises an installing part and a valve plate part; the valve plate part is arranged on the installing part and is partly opposite to the lateral oil hole; the valve plate part is arranged in a manner that when the motor drives the crankshaft to rotate along a rotation axis, the valve plate part deviates towards the direction of the lateral oil hole, relative to the axial direction of crankshaft. According to the rotary compressor, by arranging the oil rate adjusting valve, the openness and effective circulation area of the lateral oil hole can be adjusted, the oil outlet rate of the lateral oil hole is reasonably controlled; the rotary compressor is prevented from pumping large amount of cooling engine machine out of an oil pool when works at high frequency, and therefore the oil splitting rate of the rotary compressor and the oil surface stability of the oil pool are improved.

Description

technical field [0001] The invention relates to the field of rotary compressor equipment, in particular to a rotary compressor. Background technique [0002] It is pointed out in the related art that when the rotary compressor operates at high frequency, the pump oil volume at the lower end of the crankshaft is large and the flow rate is fast, and the oil volume discharged from the lateral oil hole on the crankshaft will also increase. , resulting in deterioration of the oil discharge volume of the rotary compressor, affecting the stability of the oil level of the oil pool in the rotary compressor. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the object of the present invention is to provide a rotary compressor, which can improve the amount of protruding oil in the rotary compressor and ensure the stability of the oil level in the oil pool in the rotary compressor.
