Cylinder-piston arrangement for force-generating or working machine, preferably an internal combustion engine, has piston and/or hollow chamber with cross-section whose circumference has different radii of curvature at least in some regions

摘要

The arrangement has at least one hollow chamber (2) and a piston (3) movable linearly within it, whereby a section though the hollow chamber transverse to the displacement direction is independent of the displacement position and the piston cross-section corresponds approximately to the cross-section of the hollow chamber. The piston and/or the hollow chamber has a cross-section whose circumference has different radii of curvature at least in some regions.
