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.

Electromagnet for producing a linear movement

An electromagnetic switch valve for opening or closing an oil or coolant circuit in a motor vehicle, having an electromagnet, which has a coil and a movable armature, wherein the armature is coupled to a valve element, via which a valve seat in the coolant circuit can be sealed, wherein the switch valve is designed to be pressure balanced, and the valve element, pointing in the direction of the valve seat, is designed to be at least approximately hollow-walled.

Electromagnetic solenoid valve

An electromagnetic actuator for a valve mechanism, in particular in a common rail system of a motor vehicle, comprising an armature tappet for actuating a valve element located in a channel, and comprising a pole core, the armature tappet being movable axially along a central axis of the actuator when an excitation coil of an excitation system is energized. The pole core therefore has a tubular shape and has a circumferential flange in the area of the pole core end facing the channel, said flange extending inward in relation to the central axis.

Electromagnetic actuator for a valve mechanism

An electromagnetic valve for controlling the flow of a pressure medium, said electromagnetic valve comprising a valve housing with an inlet port and an outlet port for the pressure medium; at least one passage opening, which connects the inlet port to the outlet port, for the pressure medium; a valve slide that can be moved axially between a first basic position, which closes the passage opening, and a second basic position, which opens the passage opening, by means of a solenoid coil; and a spring assembly, which positions the valve slide in the first or the second basic position when the solenoid coil is not energized. A spring excursion limiting means limits a specified spring excursion of the second spring portion to position the valve slide in an intermediate position between the first and second basic position by the energized solenoid coil. The valve slide releases at least a partial cross section of the passage opening in the intermediate position.
