GAS MACHINE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: gas machine has hollow housings of compressor, heat converter and flat mechanism of rotor-piston mechanical converter connected in series, coupled with the atmosphere, and interconnected through air ducts and gas lines tightly coupled with the housings. Means for fuel supply are mounted inside the heat converter space made up as a combustion chamber. The mechanism of the rotor- piston converter mounted inside the space of the housing has a rotor with the shaft and radial grooves wherein two rigidly interconnected same flat pistons are received to provide movement and minimum gaps. The inner space is made up as straight non-circular cylinder. The shaft of the rotor is kinematically coupled with the housing and compressor. The housing of the heat converter is provided with a hopper for supplying solid fuel made up as hollow cylinder with a port in its side made for permitting subsequent communication with the atmosphere or the space of the combustion chamber or disconnecting with them and fire grate. The cross-section of the straight non-circular cylinder of the space is defined by a curve which is the same as a conchoid. The mechanism of the rotor-piston mechanical converter can be provided with the second piston pair. The crankshaft can be provided with additional crank-pin rigidly secured to the crankshaft and kinematically coupled with the second pair of rigidly interconnected pistons mounted perpendicular to the first pair. The crank-pins are symmetrical with respect to its axis of rotation. EFFECT: enhanced efficiency. 6 cl, 7 dwg
