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

Patent number: 9551997Abstract: Electromagnetic fluid valve regulating the throughflow of a pressure medium which flows through a housing part having at least two inlet openings which lie opposite one another and at least one outlet opening for the pressure medium. It being possible for a channel which is situated between the inlet openings and the outlet opening to be closed to a greater or lesser extent by an axially movable slide for regulating the throughflow of the pressure medium, a pin protruding into the channel centrically with respect to the center axis of the fluid valve, the pin being provided, for flow guidance, with an outer contour which is of at least approximately conical, pyramidal or hyperbolic design, with the result that the pressure medium which is to flow from the inlet openings strikes the outer contour of the pin and diverted in the direction of the at least one outlet opening.Type: GrantFiled: January 23, 2014Date of Patent: January 24, 2017Assignee: KENDRION (VILLINGEN) GMBHInventors: Bjoern Bergfeld, Holger Brandenburg, Martin Ohnmacht
