摘要
A rotary cylinder piston compressor pump is provided, including a rotating shaft (2), a piston (3) and a cylinder (4). A rotating shaft hole (21) is provided in the rotating shaft (2). An oil guiding channel communicated with the rotating shaft hole (21) is provided in the cylinder (4). A recess (45) is formed in the inner end face of the cylinder (4). An oil path sealed relative to a compression cavity of the cylinder (4) is formed between the recess (45) and the piston (3). The oil path is communicated with an oil path between the piston (3) and the rotating shaft (2) and is communicated with the oil guiding channel by means of an oil returning channel. Also provided is a compressor including the compressor pump.
