FIELD: engines and pumps.
SUBSTANCE: pneumatic drive comprises compressor piston, compressor piston spring, intake and discharge valves and pneumatic accumulator. Fluid compressed in ICE cylinder thrusts against compressor piston end face surface. This makes compressor piston displace to compress atmospheric air in piston opposite end face to be fed via discharge check valve into pneumatic accumulator. At piston suction cycle end, spring arranged at compressor piston opposite end face cavity displaces the piston towards engine cylinder. Atmospheric air is sucked via intake check valve into compressor piston opposite end face cavity. Thereafter, pneumatic accumulator charging cycle is terminated to make compressor piston ready for another charging cycle.
EFFECT: unified ICE drives.
