Scroll Compressor

Abstract

A scroll compressor includes a compression unit, a rear housing including a passage formed with a flow path for the refrigerant to be expelled, and a discharge check valve varying the opening degree based on the pressure of the refrigerant, wherein the discharge check valve includes a main body connected to the passage and including a main inlet port through which the refrigerant and oil are introduced, a core unit configured to move inside the main body based on the pressure of the refrigerant, and an inner diameter-variable flow path formed by the inner diameter of the main body varying in the axial direction to minimize vibration and noise caused by pulsation and ensure stable operation regardless of pressure fluctuations in the refrigerant by installing a discharge check valve in the rear housing of a scroll compressor to separate oil contained in the refrigerant.
