Abstract
A reciprocating rocking-piston two-cycle engine where the piston is skirtless, rigidly mounted to its connecting rod, and slides up and down in a preferably waisted cylinder is shown and described. The free and of the connecting rod is laid out as an adjusted counterweight to assure smooth running of the rocking piston. An exhaust slide runs on a frontal cylinder wall and is hinged on the piston edge.

A reciprocating rocking-piston machine comprising:
- at least one cylinder forming a cylinder chamber and having a cylinder axis, a wall and a cylinder cover,
- a crank casing;
- a crank shaft rotatably supported in said crank casing and comprising at least one crank pin;
- a piston rigidly secured to integral with one end of a connecting rod and slidably received in said cylinder;
- a connecting rod bearing at the other end of said connecting rod for articulation of said rod to said crank pin;
- a counterweight at said other end of said connecting rod for increasing at least the mass of said other connecting rod end situated beyond the center of said connecting rod bearing, said counterweight being of such size and mass that the center of impact of this moving assembly with regard to the rocking piston center (2*, 147) substantially coincides with the center of the connecting rod bearing.
