Abstract (en)

[origin: EP0293847A2] A device for converting the reciprocating movement of at least one piston (8) of an internal-combustion engine (4) into an oscillating rotary movement of at least one shaft (10), the piston (8) being connected via a flexible strip (24) to a winding-up and unwinding region (20) of the shaft (10). The rotational energy existing during rotary movement of the shaft (10) is used at the end of the working stroke of the piston (8) to rotate the shaft (10) further in the same direction of rotation, so that the strip (24) is subsequently wound in the opposite winding sense onto the winding-up and unwinding region (20) of the shaft (10), and the piston (8) is thereby pulled back by the strip (24). Alternatively, two pistons (8) are provided, with a connecting rod (16) between them, together with strips (24, 24') with opposing winding directions, so that, when the one strip is wound up, the other strip is unwound, and vice versa. <IMAGE>
