| description | The utility model provides a compressor oil pumping mechanism and a compressor, and relates to the technical field of compressors. The compressor oil pumping mechanism comprises a crankshaft, an oil suction pipe and an oil suction pipe core. Compared with an existing oil pumping mechanism, the oil pumping mechanism of the compressor is simpler in structure, the assembling mode is simplified, and assembling is firm and reliable; when the oil suction pipe is applied to a compressor, the opening sectional area of the lower pipe section of the oil suction pipe is designed to be gradually reduced from bottom to top, so that a Venturi effect is generated when refrigerating machine oil flows through the oil suction pipe, the automotive force of an oil pumping mechanism in the oil suction process is increased, and the oil feeding amount of the oil pumping mechanism in low-rotating-speed operation is increased; the supporting columns, the flow guide wings and the upper pipe section of the oil suction pipe form a plura |
