AI Technical Summary

Technical Problem

The throttling control of existing scroll compressors is complex, requiring additional throttling pins and control of the diameter and inner diameter of the transverse bore, which increases production costs and complicates the structure.

Method used

An oil storage tank and a throttling channel are provided on the back end face of the stationary vortex disk, and an oil guide channel is provided inside the stationary vortex disk. The oil guide channel is connected to the oil return hole and extends through the back end face to form an oil outlet hole. The cross-sectional area of ​​the oil guide channel is larger than that of the throttling channel. Throttling control is achieved by controlling the cross-sectional areas of the throttling channel and the oil guide channel.

Benefits of technology

It simplifies the throttling control process, reduces production costs, improves cooling and lubrication effects, and eliminates the need for additional throttling pins, resulting in a simple structure.

Abstract

This application provides a scroll compressor and a vehicle. The scroll compressor includes: a housing; a moving scroll disk movably disposed within a cavity; and a stationary scroll disk fixedly disposed within the cavity, the stationary scroll disk and the moving scroll disk being connected in conjunction. A high-pressure chamber is formed between the inner wall of the cavity and the opposite end face of the stationary scroll disk from the moving scroll disk; a low-pressure chamber is formed between the inner wall of the cavity and the side of the moving scroll disk opposite to the stationary scroll disk; an oil reservoir and a throttling channel are provided on the opposite end face; an oil guide channel is also provided within the stationary scroll disk, the oil guide channel communicating with an oil return hole and extending through the opposite end face to form an oil outlet hole, the oil outlet hole communicating with the throttling channel, wherein the cross-sectional area of ​​any part of the oil guide channel is larger than the cross-sectional area of ​​the throttling channel. In the above solution, the oil reservoir and throttling channel on the opposite end face of the stationary scroll disk are sealed and isolated from the high-pressure chamber and are not interconnected. The throttling area can be controlled by controlling the cross-sectional area of ​​the throttling channel to be smaller than the cross-sectional area of ​​any part of the oil guide channel, making throttling control simpler.
