ABSTRACT:
A device for transforming an alternating motion of a piston into a circular motion of a shaft is provided. The device includes an assembly of two pistons connected by two racks alternatively in mesh with a toothed cam set on a shaft. Movement in one direction of the assembly formed by piston and racks, following an explosion in one of the cylinders, causes one of the racks to mesh with the toothed sector and to rotate the shaft. At the end of this meshing period, the cam cooperates with a roller of one of the pistons so as to ensure continuity of the drive. Then, the explosion occurs in the other cylinder causing movement of the assembly in an opposite direction and so meshing of the other rack with toothed cam set, continuing the transformation of power to the shaft.
