ROTOR-PISTON MACHINE Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: machine has reduction gear, opposite cylinders with diametrically opposite openings, crankshafts, pistons that form three chambers of alternative volume, and two pairs of connecting rods coupled with pistons in pair and provided with different crankshafts. The machine is provided with a toroidal tank having control valve, two semi-ring chambers, multiplicator of a generator and aerodynamic supports. The shaft is received in the openings of one of the cylinders perpendicular to its axis, axes of pistons and first and second shafts, kinematically connected to the slide valve of the toroidal tank. Each pair of the pistons are provided with spiders with pins kinematically connected to the shafts through connecting rods. The third shaft is provided with wheel of a fan and wheel of an expansion engine which are coupled with the semi-ring chambers. Output of the expansion engine is coupled with inlet of the fan. EFFECT: enhanced efficiency. 2 cl, 5 dwg
