TWO STAGE ROTARY COMPRESSOR

摘要

A 2-stage rotary compressor is provided to improve lubrication efficiency and operation reliability by reducing the wear of a high pressure vane by setting contact areas between vanes and rollers according to the pressure of each compression space. A high pressure compression assembly(130) has a high pressure vane(134), of which thickness(t2) is smaller than that of a low pressure vane for reducing a contact area between a high pressure roller(133) and the high pressure vane to be smaller than that between a low pressure roller and the low pressure vane, thereby reducing the wear of the high pressure vane.
