SCROLL COMPRESSOR

WIPO Patent Application WO/2020/215663

A1

Disclosed is a scroll compressor (100, 100A). The scroll compressor (100, 100A) comprises: a compressing mechanism (M), which compressing mechanism (M) comprises a fixed scroll plate (10) and a movable scroll plate (20); an exhaust check valve, comprising a valve plate (49), which valve plate (49) is mounted to be aligned with an exhaust port (P) of the compressing mechanism, with at least part of the valve plate (49) being configured to be able to selectively move towards the exhaust port (P) to close the exhaust port (P) or move away from the exhaust port (P) to open the exhaust port (P); and an vapor-spraying enthalpy-increasing channel (E), which vapor-injection enthalpy-spraying channel (E) is suitable for spraying a vapor-spraying enthalpy-increasing refrigerant fluid to a compressing cavity in the compressing mechanism (M). The scroll compressor (100, 100A) further comprises a mounting structural component (4, 4A), wherein part of the vapor-injection enhtalpy-increasing channel (E) is arranged in the mounting structural component (4, 4A), and the mounting structural component (4, 4A) is configured to limit the distance by which the valve plate (49) moves away from the exhaust port (P). The scroll compressor (100, 100A) can achieve a compact design for the scroll compressor (100, 100A).
