Abstract: An electromagnet for producing a linear movement includes a housing, an exciter coil arranged in the housing, a pole core and an armature assembly, which is mounted centrally in the exciter coil and has a displaceable main armature and a displaceable armature disc. In the de-energized state of the exciter coil, an air gap is formed between the main armature and the armature disc and, The armature assembly has an elastic element, the preload force of which can produce an elastic force fit between the main armature and the armature disc in the energized state of the exciter coil in such a way that the armature disc is moveable towards the pole core, thereby producing the air gap, as soon as the magnetic force falls below the preload force. The electromagnet as an actuator thus acts alone with a defined spring preload and spring rate of the elastic element.

Abstract: A pressure control valve for open-loop or closed-loop control of a pressure of a compressed fluid in a pilot pressure chamber includes a valve housing with at least one inlet and at least one outlet, a wall section fixedly connected with the valve housing and having a first passage channel and a first throughbore, through which the compressed fluid can flow, and forms a first valve seat. The pressure control valve also includes a tappet and first and second sealing elements. The tappet is mounted in the valve housing and movable along a longitudinal axis by an energizeable actuation device. The first sealing element is mounted so as to be movable along the longitudinal axis in the valve housing and is biased by means of a first spring into a closure position in which the first sealing element bears against the first valve seat and closes the first through-bore.

Abstract: The invention relates to a damping valve, in particular for shock absorbers of vehicles, with an adjustable damping force, in which differently sized outlet openings arranged between an inflow and an outflow can more or less be closed in order to obtain a desired damping effect. To this end, the differently sized outlet openings are more or less sealed off radially by means of a valve slide. In another embodiment, sudden pressure increases in the damping valve are automatically reduced by means of a differential area function. Due to said invention, said damping valve can be produced easily, has low leakage loss, a low tolerance chain and requires little effort for setting the desired damping.
