COMPRESSOR FOR CO2 REFRIGERANT

摘要

PURPOSE: A carbon dioxide refrigerant compressor is provided to prevent distortion of the vane by dispersing ejection pressure of the vane according to contacting the vane and an eccentric roller at a tilt. CONSTITUTION: A carbon dioxide refrigerant compressor comprises a compression part, a vane(70), and a vane reception part(44). The compression part has a cylinder(40) and an eccentric roller(60). The cylinder forms a space in order to suck and compress the CO2 refrigerant. The eccentric roller eccentrically rotates within the cylinder. The vane has a vane main body and a nose part. The vane main body slides in the cylinder inside. The nose part contacts with the eccentric roller. The vane divides the inside of the cylinder into a compression room(48) and a suction chamber(46). The vane reception part guides the sliding movement of the vane. The nose part moves according to the rotational direction of the eccentric roller.
