FIELD: engines and pumps.
SUBSTANCE: use: ICE (internal combustion engines), compressors, pumps, including multi-cylinder ones. Objective: expansion of capabilities of an opposite piston machine. Substance of the invention: the opposite piston machine comprises cylinders, pistons with fixators of dead points, hingedly installed parallel toothed racks, a shaft with a gear, engaged with these racks, at the same time in the gear the teeth are cut on the arc with length of not more than half of the circumference length, these teeth are in turns engaged with oppositely arranged toothed racks, which by yokes connect two pistons with fixators of dead points in them.
EFFECT: proposed technical solution significantly expands capabilities of a piston machine, it is reversible - makes it possible to use it as a high-speed highly cost-effective ICE, and also as a compressor or a pump, including a multi-cylinder one.
