MULTIROTOR INTERNAL COMBUSTION ENGINE Russian patent published in 2007 - IPC F02B55/00 F01C1/24 

FIELD: mechanical engineering; rotary internal combustion engines.

SUBSTANCE: proposed multirotor internal combustion engine has drive shaft, body with inner space in form of cylindrical surface with rotor rotating inside. Ribs of rotor slide along cylindrical surface. Body is provided with initiators for working stroke and holes to let in gas mixture and let out exhaust gases. Inner space is essentially round central cylinder rotor rotating in side whose section is regular multitop figure, and whose cylindrical surfaces are surfaces of sliding. Central rotor is rigidly secured on drive shaft. Axes of central cylinder, central rotor and drive shaft coincide. Body is provided with external spaces in form of round cylinders intersecting with central cylinder, axes of central and outer cylinders are parallel. Each external cylinder accommodates rotating external rotor with cylindrical sliding surfaces and ribs sliding along external cylinder. Section of external rotors is regular tultitop figure with rotation of central and each external rotor, continuous alternate sliding of rib of one of them along sliding surface of other one is provided.

EFFECT: elimination of vibration of movable parts.
