Publication number: 20240079171Abstract: 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.Type: ApplicationFiled: October 20, 2021Publication date: March 7, 2024Inventors: Joachim FLÜHS, Frank ZELANO

Patent number: 10655747Abstract: A double-armature solenoid valve may include an adjustable first armature and an adjustable second armature arranged axially opposite each other along a common adjustment axis, and a coil mechanism configured to provide a magnetic flux. The valve may also include a first restoring spring, a second restoring spring, an inlet opening arranged on an axial side of the first armature opposite the second armature, and an outlet opening arranged on an axial side of the second armature opposite the first armature. The inlet opening and the outlet opening may be connected via a fluid duct. The first armature and the second armature may respectively have a different closing time such that when an energization of the coil mechanism is at least one of interrupted and reduced the inlet opening is closable more quickly via the first armature than the outlet opening via the second armature.Type: GrantFiled: May 8, 2017Date of Patent: May 19, 2020Assignees: Kendrion (Markdorf) GmbH, Mahle International GmbHInventors: David Vopel, Marco Kiene, Frank Zelano, Joachim Fluehs, Bjoern Bergfeld, Michael Braunheim, Matthias Gaenswein, Werner Schadler

Patent number: 9599247Abstract: 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.Type: GrantFiled: June 3, 2014Date of Patent: March 21, 2017Assignee: KENDRION (VILLINGEN) GMBHInventors: Joachim Flühs, Holger Brandenburg
