ROTARY-PISTON INTERNAL COMBUSTION ENGINE Russian patent published in 1997 - IPC

FIELD: mechanical engineering; internal combustion engines. SUBSTANCE: rotary-piston internal combustion engine has housing with cylindrical working space, solid cylindrical rotor with pistons installed non-coaxially in working space. inlet and outlet valves with guides made on housing, and two valves of liquid cooling and lubrication system of rotor and pistons. Inlet and outlet ports are made on housing and through hole opening into combustion chamber for injector or spark plug. Pistons are made on form of outer ends of two rectangular plates placed for displacement in through diametral slot of rotor. Longitudinal axes of inlet and outlet ports and axis of rotor are arranged in one chordal plane of working space. Pistons, end faces of rotor and plates adjoin inner surfaces of working space with minimum clearances. Channels for cooling and lubricating liquid made inside rotor, shaft and bearings form through channel to inlet of which outlet of one valve of cooling and lubrication system is connected. Inlet of other valve of system is connected to outlet of the channel. Inlet and outlet valves are installed opposite to corresponding ports. EFFECT: enlarged operating capabilities. 3 dwg
