Abstract

The invention relates to an adjusting device (1) having at least one tappet assembly (3, 6). The at least one tappet assembly (3, 6) comprises a tappet (31, 61), at least one guide cylinder (34, 64),and a pole core (44, 74). The tappet (31, 61) is arranged in the guide cylinder (34, 64) in a movable manner along a longitudinal axis (30, 60), and a non-magnetic connection socket (43, 73) is arranged between the guide cylinder (34, 64) and the pole core (44, 74). The guide cylinder (34, 64) and the pole core (44, 74) are arranged at a distance to each other in the longitudinal axis (30, 60) bymeans of the connection socket (43, 73).

Description

technical field [0001] The invention relates to an adjusting device according to the preamble of claim 1 and to a motor vehicle having such an adjusting device. The invention relates in particular to a control device for varying the valve opening and / or valve opening time in an internal combustion engine and / or to a control device for deactivating partial cylinders of an internal combustion engine. Background technique [0002] Regulating devices, in particular with electromagnetically operated actuators, are used in motor vehicle technology for opening and closing intake and exhaust valves of diesel and / or gasoline engine cylinders, which will A fuel mixture is introduced into the combustion chamber and combusted exhaust gases exit the combustion chamber. In order to achieve the highest possible efficiency of the internal combustion engine, the opening and closing times of the valves need to be precisely adjusted, which takes place via the valve control or the valve train....
