ENGINE-COMPRESSOR Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: engine-compressor has piston compressor and two internal combustion engines arranged coaxially in common unit. Each internal combustion engine has nozzle, spark plug and piston freely moving in cylindrical space. Compressor is separated from engines by partitions from two sides. Each partition has hole along axis to receive rod. Engine pistons are secured on rod ends, and compressor piston is connected to middle part located in compressor. Longitudinal slot made on side surface of compressor cylindrical housing is used to enclose control rod in form of cantilever connected to compressor piston. Control rod is provided with permanent magnet on its end. EFFECT: simplified design and increased efficiency of engine-compressors with freely moving pistons. 3 cl, 2 dwg
