Stageless variable control time setting device for engine valves

摘要

The setting device has a stator (1) fixed to the engine casing (17) and a rotor in the form of a step motor acting via the central engine management on the setting shaft (3), which passes axially concentrically through the camshaft so that the gear wheels (9,12) act on the gear segment (18) in the camshaft setting ring (10). This moves the camshaft (4) with cams (6) relative to the zero setting, so that the camshaft setting rung is guided through the hub (15) by means of the annular groove (16).
