TLDR
In this paper, a compressor and a refrigerating device are described, and a first oil storage groove is formed in the outer wall of the piston rod, and the oil discharging end of the oil suction pipeline communicates with the inner wall of air cylinder.Abstract:
The invention discloses a compressor and a refrigerating device and belongs to the technical field of compressors. The compressor comprises a compressor body. An air cylinder, a piston mechanism arranged in the air cylinder and an oil storage part are arranged in the compressor body. The piston mechanism comprises a piston head and a piston rod. The oil storage part is used for storing lubricatingfluid. A first oil storage groove is formed in the outer wall of the piston rod. The compressor body is further provided with an oil suction pipeline. The oil suction end of the oil suction pipelinecommunicates with the oil storage part. The oil discharging end of the oil suction pipeline communicates with the inner wall of the air cylinder. When the piston mechanism conducts reciprocating compression motion in the axial direction of the air cylinder, the oil discharging end of the oil suction pipeline and the first oil storage groove can be switched between a communication state and a separation state. By means of the compressor, due to the oil storage groove of the piston mechanism and the oil suction pipeline communicating with the oil storage groove, the compressor can utilize negative pressure generated during the reciprocating motion of the compressor to automatically extract the lubricating liquid to lubricate the piston mechanism during running, the internal structure of thecompressor is simplified, and running stability of the compressor is improved.read more
