Title:
COMPRESSOR AND REFRIGERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/029561
Kind Code:
A1
Abstract:
Disclosed are a compressor and a refrigeration apparatus. The compressor comprises a machine body, wherein the machine body is internally provided with a cylinder (3), and a piston mechanism and an oil storage part (5) which are arranged inside the cylinder (3); the piston mechanism comprises a piston head (41) and a piston rod (42); the oil storage part (5) is used for storing a lubricating fluid; an outer wall of the piston rod (42) is provided with a first oil storage tank (61); and the machine body is further provided with an oil suction line (7), with an oil suction end (71) of the oil suction line (7) being in communication with the oil storage part (5), and an oil discharge end (72) thereof being in communication with an inner wall of the cylinder (3). When the piston mechanism performs compression in a reciprocating motion in an axial direction of the cylinder (3), the oil discharge end (72) of the oil suction line (7) and the first oil storage tank (61) can be switched between a state in which same are in communication with each other and a state in which same are separated from each other. According to the compressor, by means of providing, in the piston mechanism, an oil storage tank and an oil suction line (7) in communication with the oil storage tank, when the compressor is in operation, the piston mechanism can be lubricated by a lubricating fluid that is automatically drawn under negative pressure generated during the reciprocating motion thereof, thereby simplifying the internal structure of the compressor and improving the stability of operation of the compressor.
