Abstract:
1. An internal combustion engine, comprising two cylinders located opposite to one another, two pistons each movable in a respective one of said cylinders and connected with one another so as to move jointly in said cylinders in two opposite directions; and means for converting the joint movement of said pistons into a rotary movement; valve means provided in said cylinders, so that when said pistons jointly move in one direction one of said pistons performs a working stroke in one of said cylinders, while when said pistons jointly move in an opposite direction the other of said pistons perform a working stroke in the other of said cylinders; and further comprising means for connecting said pistons with one another and including two piston rods each connected to a respective one of said pistons and also connected with one another by a slider, said converting means including two driving pinions located near one another in an axial direction and both connected with said slider so as to rotate in opposite directions, and a pinion gear engaging with said driving pinions and rotatable by the latter to transmit rotation from said pinion gear to a further transmission.
