COMPRESSOR Russian patent published in 1999 - IPC

FIELD: mechanical engineering. SUBSTANCE: compressor is designed for compressing air to high pressures and one can be used also as vacuum pump. Working liquid plays part of pistons in compressor with vertical cylinders. Suction and delivery valves are installed in cylinders. Rotary motion of engine is converted into reciprocation of pistons by hydraulic converter made in form of pump and control valves with system of pipelines to change cycling on cylinders. With piston moved from upper dead center into lower dead center, working liquid gets into closed reservoir installed between pump suction pipe and cylinders. Reservoir has vertical drain pipe whose upper part extends to cylinder head mark and opens into atmosphere. EFFECT: possibility of building high pressure at reduced energy taken for compression. 2 dwg
