Sealing system for a rotary-piston compressor

Abstract

The invention relates to the rotary piston machines, namely, to the working volume sealing systems of the said machines and can be used in the gas (air)’ and refrigerating compressors, heat’ and vacuum pumps and in the internal-combustion engines. The rotary piston compressor sealing system comprises the radial and butt sealing bars configured in the rotor slots, tightened towards the working surfaces by expanders and interacting with the sealing cylinders wherein the radial and butt sealing bars are made from antifriction composite material and each of the sealing cylinders is configured conjointly with one of the ends of one butt sealing bar. Also, a second embodiment of the rotor piston compressor sealing system is disclosed. The technical result consists in the increasing of the efficiency of the sealing system’ and the whole compressor operation, simplification of the system production process, simplification and labor intensity reduction of the system assembly and maintenance process, increasing of the working chambers leakage tightness, increasing of the system reliability and durability and improvement of the compressor performance related to the bleeding and the dynamic pneumatic process as a whole.
