Abstract

A switching valve module is provided in a connecting rod of a reciprocating internal combustion engine in order to control a distributing device for changing the compression ratio of a cylinder unit of the reciprocating internal combustion engine. In order to provide an arrangement of a mechanically actuated switching valve module which can be advantageously integrated into the connecting rod, the switching valve module should be arranged in a module housing of which at least partly has an outer cylindrical contour and a transverse through-bore for receiving a control slide valve, and the cylindrical section of the switching valve module can be inserted into a receiving bore in the connecting rod that is transverse to a longitudinal central axis of a connecting rod bearing eye.
