ABSTRACT:
The invention relates to an assembly for converting the reciprocating motion of at least one piston of a combustion engine into an oscillating rotary motion of at least one shaft, the piston being coupled with the shaft via a flexible band connected with a winding on and off area of the shaft. The rotational energy existing in the rotary motion of the shaft is utilized to continue rotation of the shaft in the same direction when the end of the pistons's working stroke is passed, so that the band is then wound onto the winding on and off area of the shaft in the opposite direction, thereby causing the band to pull back the piston. Alternatively, two pistons with opposite working stroke directions are present whose bands are connected to the shaft with opposite directions of winding. Due to a connecting rod between the two pistons, the working stroke of one piston pushes the other piston back to its starting position.
