VANE ROTARY TYPE COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To solve the problem wherein vibration and noise are generated and abrasion of a vane is propelled by insufficient vane back pressure due to the lubricating oil contaminated with a compressive fluid (refrigerant gas) led to a vane back pressure space. SOLUTION: A bubble contamination preventing means is provided in an inlet of an oil supply passage connected to the vane back pressure space to supply the only lubricating oil, from which bubbles are separated, to a compression mechanism.
