GAS ENGINE Russian patent published in 1996 - IPC

FIELD: power engineering. SUBSTANCE: gas engine has systems for controlling speed, supplying, lubricating, cooling, igniting and gas dispensing as well as three housing of compressor, heat converter, and plane mechanism of a rotor-piston mechanical converter, mounted in series. The devices are connected with the atmosphere and interconnected with air ducts and gas ducts tightly coupled with the housings. The space of the heat converter is made as a combustion chamber and provided with facilities for supplying fuel. The mechanisms of the rotor-piston mechanical converter has hollow rotor with shaft and radial grooves. The hollow rotor is mounted inside the space of the rotor-piston mechanical converter. At least two same plane pistons are set in the grooves for permitting movement with a minimum spaced relation. The inner side of the space of the rotor- piston mechanical converter is made up as a straight noncircular cylinder. The shaft of the rotor is kinematically connected with the housing and compressor. The housing of the heat converter is provided with a hopper for supplying solid fuel made up as a hollow cylinder with a port in its side surface. The cylinder can be in communication with the atmosphere or the space of the combustion chamber or can be disconnected with them and fire grate. The pistons of the rotor-piston mechanical converter are rigidly interconnected in pair. The end part of each piston is made up as a part of the straight circular cylinder of a given radius. The cross- section of the straight noncircular cylinder of the space of mechanical converter mentioned above is defined by a curve which is similar to conchoid or circumference. The gass engine is additionally has rollers pivotally connected with each piston and kinematically connected with the inner side of the groove in the rotor or, vise versa, the rollers are pivotally connected with the rotor and kinematically connected with the piston and gear transmission which includes large wheel fixed to the rotor and small wheel pivotally connected with the housing and the middle part of the two rigidly interconnected pistons. The converter is made up as a underground nuclear plant provided with a control system and air space surrounding the plant. The spring-loaded valve is mounted in the gas duct of the housing of the rotor-piston mechanical converter. The valve is kinematically coupled with the housing and cam rigidly secured to the rotor. The gas dispensing system is provided with a slide valve made in the rotor and having passageways arranged to permit them to be periodically connected with the working space of the rotor-piston mechanical converter and with its inlet pipe line. EFFECT: enhanced efficiency. 6 cl, 4 dwg
