ROTARY-PISTON MULTICAM FOUR-STROKE ENGINE

FIELD: mechanical engineering; engines. SUBSTANCE: engine housing is made in form of cylindrical flat split box on outer surface of which two cylinders per compartment are installed in two relatively perpendicular diametric axes at two opposite sides of housing. Pistons of cylinders in one compartment are in one phase. Two cylinders in one compartment along two other relatively perpendicular diameter axes shifted relative to first ones through are angle of 45 degrees and also arranged at two sides of housing, but their pistons are in opposite phase. Pair of cylinders of each compartment has common combustion chamber arranged under compartment cover. Rods of all pistons are hinge secured to piston at one side. Rods of two cylinders of one compartment are connected by other ends with link hinge-mounted in holes of corresponding arms of bell cranks secured for movement on inner cylindrical surface of housing. Second arm of each bell crank is connected with link of cylinder rods of adjacent compartment. Rollers are installed in middle of each link connecting two rods in space between rods. Rollers are in contact with path of multicam rotor rigidly secured on engine shaft. EFFECT: enlarged operating capabilities. 2 dwgo
