Abstract (en)
[origin: WO8301816A1] A positive displacement machine, particularly an internal combustion engine, comprises an oscillating piston connected to a piston pump. The cylinder of the pump is connected through valves to a pressure accumulator and to a substantially pressureless tank for the gas to be compressed. The piston (3) of the motor (1) is integral with at least one piston (7) of a pump (8). The valves (10, 11) of the pump (8) which are possibly comprised of slides are positively actuated by a separate independent motor (25).
