FIELD: machine building.
SUBSTANCE: invention relates to piston compressors. Movement conversion mechanism for piston machine comprises at least two cylinders with pistons installed in them, crankshaft and Chebyshev’s mechanism. Chebyshev's mechanism is formed by the shaft knee, swinging rocker arm and con-rod, which is isosceles triangle with hinges fixed in tops, one of which is connected to connecting rod of crankshaft, the second one – to swinging rocker arm, and the third one is connected to one of pistons by rod. At that, the crankshaft of the motion conversion mechanism contains at least the second bend shifted relative to the first one by 180°, with Chebyshev's mechanism connected with the second shaft bend and rod with the second piston.
EFFECT: reduced vibration, noise during operation of mechanism, as well as increase in its reliability.
