FIELD: mechanical engineering; piston machines.
SUBSTANCE: invention relates to devices converting rotation of piston machines. According to invention, proposed device contains crankshaft, eccentric and internal gear pair. Eccentric is rigidly connected with smaller spur gear forming internal pair with gear of diameter twice as great as diameter of smaller spur gear. Radius between center of eccentric and center of crank of crankshaft can be smaller than radius between central axis of crankshaft and axis of crank. To change degree of compression, displacement and ignition advance angle, larger diameter gears have freedom of circular displacement within the limits of control angle λ. At λ=90° piston displacement changes up to its cutting out of work when shaft is rotating.
EFFECT: improved efficiency of piston machine.
