Document Type and Number:
WIPO Patent Application WO/2024/037245
Kind Code:
A1
Abstract:
A scroll compressor and a refrigeration apparatus. The scroll compressor comprises a main frame, a movable scroll plate and a stationary scroll plate assembly, wherein the movable scroll plate is mounted on the main frame, and the movable scroll plate and the stationary scroll plate assembly match each other to form a compression cavity; and the scroll compressor further comprises an oil interception device, which is mounted on the stationary scroll plate assembly. An exhaust chamber, an exhaust hole by means of which the exhaust chamber and the compression cavity are in communication, and a discharge channel in communication with the exhaust chamber are formed in the stationary scroll plate assembly; the oil interception device is used for blocking an oil liquid from entering the discharge channel via the exhaust chamber; and the movable scroll plate is provided with an assembly surface facing away from the stationary scroll plate assembly, and an assembly clearance is provided between the assembly surface and the main frame. In the present application, the oil liquid, which is in an airflow, is blocked from entering the discharge channel by means of the oil interception device, such that the oil liquid enters an oil groove along a second oil hole and a first oil hole, so as to perform lubrication between the main frame and the movable scroll plate, thereby reducing friction loss between the main frame and the movable scroll plate, and thus improving the operation performance of the compressor.
