INTERNAL COMBUSTION ENGINE WITH GEAR PISTONS Russian patent published in 2016 - IPC F02B55/02 F01C1/44 

FIELD: engines and pumps.

SUBSTANCE: internal combustion engine with gear piston comprises rotor with possibility to turn on shaft withs four bearing pistons installed one by one between its splines. Pistons have possibility of performing reciprocal-rotary motion at its two cylindrical surfaces with different radii from one centre. Rotor is fitted in piston unit between two rigidly interconnected closing top flat surfaces, arranged one into another coaxially with oval cylinder surfaces having equal focal lengths distances, closed from below by base and disc rotor. Unit of pistons with rotor is mounted on and attached to base. Outer surface of inner oval cylinder piston unit is made of two oval cylindrical surfaces of two oval discs rigidly interconnected by cylinder. On every oval disk of pistons unit there are oval support surfaces and on each face of piston rod by one spur with hole are made, in which there is one axis with two bearings is mounted. Through bearings rod pistons are supported by oval support surfaces of two oval discs of pistons unit.

EFFECT: simplified engine design.
