Geometric theory for a translational rotary compressor

This paper presented a new frame rotary type compressor, named translational rotary compressor to overcome the large friction energy loss and the sever wear of structure of other compressor. The compressor was made up of fixed cylinder, swing vane and translational rotor. During the whole cycle, the procedure of inflow, compress, air discharge operated continuously in the working chamber formed by the inside surface of cylinder, vane and the outside surface of bladed rotor. Thereby, the working state is smooth. The operation principles, structure characteristics and geometric theory of this mechanism were formulated and analyzed, and the calculation formulae for displacement volume, chamber pressure and thermodynamic properties were deduced. The analysis results show that this mechanism is of simple structure, no wearing parts, easily airtight, slight friction and lower cost; and fits for various fluids.
