Patent number: 9885428Abstract: A magnet valve coil unit includes a magnet coil and a circuit board connected thereto, encased by a molding material. An LED on the circuit board signals a switching status of the magnet coil. The LED is surrounded by the molding material at least in part. A light guide element is arranged in contact with the LED such that it directs light radiated from the LED to an external surface of the magnet valve coil unit. The magnet valve coil unit is manufactured by applying a deformable, transparent mass on the LED of a pre-assembled component containing the magnet coil and the circuit board on which the LED is arranged, and placing the pre-assembled component in a tool mold. The light guide element is arranged to be in contact with the transparent mass, and the pre-assembled component is encased with a molding material.Type: GrantFiled: March 5, 2015Date of Patent: February 6, 2018Assignee: BUERKERT WERKE GMBInventors: Christian Bezold, Daniel Bierut, Martin Hettinger, Sebastian Kahl, Ottmar Mueller, Christian Weber

Patent number: 9856993Abstract: A valve device includes a valve having an electrodynamic actuator. The electrodynamic actuator includes a movably mounted control element having a coil and a magnet arrangement immovable relative to the coil. A driving force caused by energization of the coil and transmitted to the control element substantially is linearly dependent on the current intensity. A front-end electronic unit is connected with the coil and includes a capacitor connected in parallel to the coil. A method for controlling a valve as mentioned above provides that, upon actuation of the electrodynamic actuator, during energization of the coil by a voltage source, a capacitor connected in parallel to the coil is charged. After termination of the energization by the voltage source, the coil is energized further by a discharge of the capacitor.Type: GrantFiled: November 30, 2015Date of Patent: January 2, 2018Assignee: Buerkert Werke GmbHInventors: Maik Fuchs, Ralf Scheibe, Sebastian Kahl

Patent number: 9524818Abstract: An electromagnetic lifting armature actuator, in particular for valves, comprises an armature rod which can be shifted in the direction of its longitudinal axis, and a magnetic yoke comprising a first yoke leg and a second yoke leg which is coaxial to the armature rod. A first magnet coil encloses the first yoke leg and a second magnet coil encloses both the second yoke leg and the armature rod. One of the magnet coils is a working and measuring coil which can be selectively used for enhancing the magnetic force or for determining a position of the movable armature rod.Type: GrantFiled: March 29, 2012Date of Patent: December 20, 2016Assignee: Buerkert Werke GmbHInventors: Sebastian Kahl, Martin Ottliczky

Patent number: 9134107Abstract: A solenoid valve having a condition monitoring unit, and a method of condition monitoring this solenoid valve are specified. A core of the solenoid valve can be shifted with respect to a holding coil and a measuring coil. A reading voltage is applied to the measuring coil, and the current intensity of a current flowing through the measuring coil is determined at a first and a second time. The first measuring is performed during a switching-on or switching-off operation of the current flowing through the measuring coil. The second measuring is performed when the current intensity of the current flowing through the measuring coil has reached a stationary condition.Type: GrantFiled: March 25, 2013Date of Patent: September 15, 2015Assignee: Buerkert Werke GmbHInventors: Sebastian Kahl, Jochen Schenkel

Publication number: 20100123093Abstract: An electromagnetic drive with a lifting armature is disclosed, in particular for a valve, which, while having small dimensions, is suitable to achieve high magnetic forces and the components of which can be freely combined with one another in a large variety of ways. This allows an adaptation to a specified structural space without specific components having to be fabricated. The same standardized components are just combined with each other differently. The drive includes a magnetic yoke with two parallel spaced yoke legs, a yoke rod extending perpendicular to and connecting the yoke legs, a yoke stud extending parallel to the yoke rod and spaced from the yoke rod, and a core plug extending coaxially with the yoke stud. The core plug is axially movable and passes through one of the yoke legs. The core plug further defines an air gap with the yoke stud.Type: ApplicationFiled: November 18, 2009Publication date: May 20, 2010Inventors: Olaf Beyer, Martin Doerr, Willheim Gauss, Martin Hettinger, Sebastian Kahl
