Abstract

628,380. Rotary compressors or engines. FAIRWEATHER, H. G. C. (Svenska Turbinfabriks Aktiebolaget Ljungstrom). Sept. 30, 1947, No. 26404 [Class 110(ii)] A meshing screw compressor or engine comprises an outer rotor 1 with an internal thread, and an inner, eccentric rotor 8 with an external thread, the threads engaging at the upper parts of the working chamber. For a compressor crescent shaped chambers conduct fluid from an inlet 5 to a discharge port 7 and passages 13, 14. In Fig. 2 the piston 8 is hollow and has another thread 15 on its inside which engages a thread 16 formed on a member 17 rigidly connected to the rotor 1. This gives working chambers both inside and outside the rotor 8. Fluid enters through a port 5, is compressed, and discharged through passages 13, 14. Sheet-metal packing strips 18, 19, of spiral shape are provided. Spring 21 acts through bushes 20 to press the packings axially. The piston 8 may be formed by two resilient members engaging each other to secure tight sealing. Each comprises an angle bar bent to a spiral shape. By introducing gas through the port 7, the rotor may be driven as an engine.
