A piston-and-control rod assembly includes a hollow piston having a skirt; axially spaced, circumferential piston ring grooves provided in the skirt; a radial crown having an inner face; and a bearing block projecting from a central portion of the inner face and having a bearing bore oriented radially to the piston axis. The bearing bore is situated in a zone approximately radially adjacent the piston ring grooves. The assembly further includes a connecting rod having a main connecting rod body; a head portion located at an end of the main connecting rod body and being laterally offset relative thereto in a direction of offset; and a piston pin affixed to the head portion and projecting unilaterally therefrom in a direction opposite to the direction of offset. The piston pin is received in the bearing bore.
