Abstract

PURPOSE:To improve the discharge and volumetric efficiency of a compressor by meanderingly arranging discharge pipes communicating with the radial discharge ports of a Wankel type compressor on its plane of rotation. CONSTITUTION:Discharge pipes 4a, 4b communicating with radial discharge ports 3a, 3b of a Wankel type compressor are arranged on the plane of rotation of the compressor, and have their sectional area enlarging gradually as they approach to their junction. Consequently, discharge gas can flow smoothly without forcible change in its flow direction to improve the discharge efficiency of the compressor.
