Device for reversing the operation of a gas exchange valve for an internal combustion engine has a camshaft with valve cams, a pivoted lever supported on a component fixed on the engine and a coupling link moving on the lever

摘要

A pivoted lever (10) supported on a component fixed on the engine has a sensing device (30) to hold a sensing element on a valve cam (70) and operates the valve. In a first position a coupling link (18) moving on the pivoted lever transfers motion in the sensing element through the valve cam onto the pivoted lever. In a second position it stops the transfer of motion. A switching device (22,52) adjusts the coupling element between the first and second positions.
