Abstract

The invention is related to rotary machines, which can be used, for instance, as air compressors. The goal of this invention is to build up efficiency of machine as an air compressor at 5 high-speed rotation. The set task is resolved due to a revolving bushing installed on bearings inside housing, an intake port is made tangential toward bushing rotation direction, and a bushing has longitudinal ports. There are some other features making this invention distinguished from a prototype. Higher efficiency due to lower friction of revolving bushing and because of ability to use dynamics of incoming air streams is a definite advantage of the claimed invention.
