Camshaft adjusting device for adjusting valve timings of gas shuttle valves of e.g. diesel engine, has camshaft connected with adjuster via screw connection that is made by screw element, where element includes two threaded sections

摘要

The device (1) has a cam shaft (2) rotationally connected with an adjuster (3). The adjuster partially surrounds a rotational torque introducing element for forwarding torque from the torque introducing element to the camshaft such that an angular position between the adjuster and the torque introducing element is changed, where the camshaft is connected with the adjuster via a screw connection (4). The screw connection is made by a screw element (5) that includes two threaded sections (9, 10) and two thread pitches, where the threaded sections are different from each other. The screw element is designed as a screw or threaded spindle (6) with an external thread, as a nut with an internal thread or as a central valve.
