INTERNAL COMBUSTION ENGINE Russian patent published in 2011 - IPC F02B75/32 

FIELD: engines and pumps.

SUBSTANCE: internal combustion engine consists of fixed cylinders 1 located in the form of V with pistons 2 and piston-rods 3, distribution shaft 4 with cams 5, piston unloading mechanism under action of lateral forces in cylinder-and-piston group, made in the form of straight shaft 6 with freewheel clutch installed on it on one of the ends of outer cage 8 to which there rigidly attached is gear wheel kinematically connected to piston-rod 3 the contact surface of which is made in the form of gear rack, and to the other end of outer cage 8 there attached is conical tooth gear connected through conical pair to the similar conical gear wheel of outer cage of freewheel clutch of the other pair of V-located cylinders. Distribution shaft 4 is kinematically connected to intermediate shaft on which there installed is freewheel clutch the outer cage of which is also made in the form of gear wheel and is engaged with gear wheel 9. Straight shaft 6 is rigidly attached to inner cage 18 of freewheel clutches.

EFFECT: reducing mechanical losses by reducing the actions of lateral loads in cylinder-and-piston group and improving operating characteristics.
