Abstract

The invention provides a rotary compressor which comprises a shell and a compression pump body arranged in the shell, wherein the bottom of the shell is provided with an oil pool used for storing lubricating oil; the compression pump body is provided with a valve seat concave part used for installing an air outlet valve plate; the compression pump body is also provided with an oil return channel, and the lubricating oil accumulated in the valve seat concave part can flow back into the oil pool at the bottom of the shell through the oil return channel; the inner end of the oil return channel is communicated with the valve seat concave part; the outer end of the oil return channel extends to the outer edge of the compression pump body. According to the rotary compressor, the lubricating oil accumulated in the valve seat concave part can flow back into the oil pool at the bottom of the shell of the rotary compressor through the oil return channel, so that the effects of reducing the viscous resistance of the air outlet valve plate and reducing the oil yield of the compressor can be achieved, and the performance of the rotary compressor can be improved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a rotary compressor. Background technique [0002] Such as figure 1 As shown, it is a compression pump body 10 of an existing rotary compressor. The compression pump body 10 is a single-cylinder type, including a cylinder 11, a main bearing 12, an auxiliary bearing 13, a crankshaft 14, a rolling piston 15 and sliding vanes, etc. , the cylinder 11 is provided with slide slots, the main bearing 12 and the auxiliary bearing 13 are installed on the upper and lower end faces of the cylinder 11, the main bearing 12 is provided with a valve seat recess 121 for installing the exhaust valve plate, and the rolling piston 15 is arranged on the cylinder 11, driven by the crankshaft 14, the rolling piston 15 rotates, and drives the sliding vane to reciprocate in the sliding vane groove, thereby realizing the working cycle of suction-compression-exhaust. In order to reduce the airflow no...
