GAS MACHINE Russian patent published in 1995 - IPC

FIELD: mechanical engineering. SUBSTANCE: gas machine has hollow housings of compressor, heat converter, and rotor-piston for converting heat power into mechanical work connected in series, which are interconnected and connected with the atmosphere through air and gas pipe lines tightly coupled with the housings. The cylindric hollow rotor with a groove is mounted inside the rotor-piston converter, rigidly coupled with the shaft, and kinematically coupled with the housing and compressor. The piston is received in the groove of the rotor for permitting movement and sliding contact with the rotor groove side and housing and rigidly coupled with a tie mounted inside the space of the rotor for permitting rotation coaxially to the housing space and means for controlling gas exchange. The housing of the heat converter is provided with a hopper for supplying solid fuel constructed as a hollow cylinder with a port in its side, which can be in communication with the atmosphere or space of the combustion chamber or disconnected from them, and fire grate. The rotor-piston converter can be coupled with a slide- counterweight and roller received in the rotor groove and kinematically coupled with the piston and the rotor groove. The kinematic connection of the slide with the piston is constructed as a pivot and three pairs of conjugated cylindric sides of the piston and the slide respectively, which are concentric to the pivot axis and arranged so that the piston is [ - shaped and slide has two L shaped parts with L shaped groove between them wherein the piston is received. The roller is mounted coaxially to the pivot for permitting rolling in the groove of the housing. The counterweight is fixed to the tie of the piston from the side opposite to the piston. The heat converter can be made up as an underground nuclear reactor provided with a control system and gas space connected with the gas and air pipe lines of the machine and arranged about the outer side of the nuclear reactor. EFFECT: enhanced efficiency. 4 cl, 3 dwg
