Abstract

A linkage for operating a control element of an internal combustion engine is constructed in a manner such that a change in the inclination of the position of the internal combustion engine has no effect, or merely an intentional, minor effect on the relative position of a linkage operated control element for the internal combustion engine. In accordance with a first embodiment, by appropriately dimensioning and positioning a regulating lever along the longitudinal shaft directly operating the control element, rotation of the longitudinal shaft, during inclination of the engine, is matched, or caused to differ by a predetermined amount, so as to maintain a desired relationship between the position of the control element relative to the engine. In accordance with a second embodiment, a resilient elastic element that is torsionally rigid, but otherwise resilient is interconnected with the longitudinal shaft in a manner to cause the rotation of the shaft to match or differ by a predetermined amount from the angle of inclination of the engine so as to maintain the desired positional relationship between the control element and the engine.
