TL;DR: In this paper, a compressor with a cylinder, a piston mechanism arranged in the cylinder and an oil storage part is used for storing lubricating fluid, and an elastic deformation oil suction valve plate is placed in the first oil storage groove.

TL;DR: 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.

TL;DR: In this article, a compressor and a refrigeration apparatus are described, where the compressor is equipped with an oil storage tank and an oil suction line, which can be switched between states in which same are in communication with each other and a state in which different states are separated from each other.

TL;DR: In this article, a compressor and a refrigeration device are used to supply a lubricant to a compressor by means of the negative pressure generated by its reciprocating movement during operation, the lubricating fluid to lubricate the piston mechanism, and the automatic lubricant supply operation can be realized without an additional lubricant pump device, simplifying the internal structure of the compressor, and improving the operational stability.
