Document Type and Number:
WIPO Patent Application WO/2023/174418
Kind Code:
A1
Abstract:
Disclosed in the present invention are a compressor and a refrigeration apparatus. The compressor comprises: a piston cylinder, which comprises a cylinder head and a cylinder body with a piston chamber; a piston, which moves in a reciprocating manner in the piston chamber; a discharge valve, which is arranged at one end of the cylinder body, wherein a discharge cavity is formed between the cylinder head and the discharge valve, and the discharge valve has a closed state and an opened state; an oil intake passage, which supplies oil to a gap between the cylinder body and the piston; an oil output channel, which communicates with the piston chamber; and a cylinder head cover, which is arranged outside the cylinder head. By means of the present invention, the temperature of the surface of the cylinder head can be effectively reduced, such that the working efficiency of the compressor is improved.
