ENGINE-COMPRESSOR UNIT Russian patent published in 1997 - IPC

FIELD: mechanical engineering; internal combustion engines; installations with engine and compressor units for use on mobile compressor plants and jet piston engine plants. SUBSTANCE: to provide large supercharging of cylinders with compressed air at a pressure of 2 kg/cm², pistons and rods are hollow, thin-walled, and are provided with stiffening ribs and cylindrical bosses with rods fitted in bosses. Reed valves are installed in pistons. To provide starting at low compression ratio, inlet branch pipes are installed on compressor cylinders. Each branch pipe has two read valves and throttle valve with lever secured on turning axle. To unload electric starter, reed valves are installed on compressor cylinders and outlet branch pipe. These valves open automatically at starting under action of pushers and cams mechanically coupled with control handle. To reduce hydraulic losses, reed valves are installed at compressor cylinder inlet. Taper boss and fairings cast integral with cylinder are made for fastening the valves. EFFECT: enlarged operating capabilities. 4 cl, 6 dwg
