Patent number: 11302468Abstract: An electromagnet and method for producing an electromagnet. The electromagnet includes a sheet metal casing encompassing a magnetic coil at its end face on a magnetic pole side and extends into an interior of the magnetic coil and forms, in this case, a magnetic pole which interacts with a magnet keeper. The electromagnet enables actuation of a valve, a coupling or a reciprocating pump. The structure is achieved with as few cutting processes as possible to be used for generating the individual parts and as small a number as possible of individual parts is to be used per electromagnet.Type: GrantFiled: April 26, 2019Date of Patent: April 12, 2022Assignee: Thomas Magnete GmbHInventors: Edwin Kreuzberg, Thomas Rolland, Olaf Ohligschlager, Thomas Baum

Patent number: 10935147Abstract: An electromagnetically actuated valve. The electromagnetically actuated valve with a small longitudinal extension, allows great through-flow quantities for the fluid with a small pressure difference. It is intended in this case that it should be producible cost-effectively in large unit numbers. An armature carries a plurality of valve bodies arranged in a point-symmetrical manner which together form a movable valve, wherein the plurality of valve bodies interact with a same plurality of valve seats which together form a stationary valve. The valve can be used along with a pump, a tank and/or other fluid units in assemblies for conveying mixtures of gas and liquid.Type: GrantFiled: April 26, 2019Date of Patent: March 2, 2021Assignee: Thomas Magnete GmbHInventors: Edwin Kreuzberg, Fabian Rösner, Olaf Ohligschlager, Thomas Baum, Diego Lehmann

Patent number: 10670009Abstract: A controller of an electromagnetically driven reciprocating pump influences velocity of the magnetic armature by switching voltage applied to the electromagnet depending on the position of the magnetic armature, its position determined from state variables of the electromagnet. A processor calculates electrical resistance of the magnetic coil from the voltage and current measured by the measuring device, and calculates the temporal change of the linked magnetic flux in the electromagnet from the electrical voltage, the current and the resistance of the magnetic coil, and calculates the linked magnetic flux in the electromagnet from an earlier magnetic flux and from the temporal change, and determines the position of the magnetic armature from the linked magnetic flux in the electromagnet and the electrical current through the magnetic coil, and switches the voltage at the magnetic coil by the switching device depending on the position of the magnetic armature.Type: GrantFiled: August 4, 2015Date of Patent: June 2, 2020Assignees: Thomas Magnete GmbH, TECHNISCHE UNIVERSITAT DRESDENInventors: Axel Müller, Thomas Kramer, Martin Petzold, Jürgen Weber, Olaf Ohligschlager

Patent number: 9394890Abstract: A reciprocating-piston pump with plain bearing traversed by flow. The reciprocating-piston pump is driven by an electromagnet to have a bearing of the piston in a cylinder, which bearing is protected against local overheating and from which bearing decomposition and reaction products and any wear products generated are discharged. For this purpose, elongate helical depressions are provided in one of two bearing surfaces in a bearing gap between the piston and the cylinder, which depressions are traversed entirely or partially by a flow of the liquid which is delivered by the piston acting in interaction with other components of the reciprocating-piston pump for the delivery rate of the reciprocating-piston pump. Reciprocating-piston pumps of the described type can be used as dosing pumps and as delivery pumps in fuel-operated standstill heaters, auxiliary heaters and exhaust-gas purification systems in vehicles.Type: GrantFiled: March 27, 2013Date of Patent: July 19, 2016Assignee: Thomas Magnete GmbHInventors: Michael Feckler, Mike Heck, Axel Muller, Olaf Ohligschlager, Tebea Reinschmidt, Robert Wellnitz

Patent number: 6959732Abstract: At least one solenoid actuator and a valve are at least partially positioned within a body of an hydraulic device. The solenoid actuator includes at least one solenoid coil mounted to a stator that defines a guide bore in which a push pin moves between a first position and a second position. The valve includes a valve member that is operably coupled to move with the push pin. The push pin is attached to an armature that is positioned adjacent the solenoid coil. In order to increase the durability of the solenoid actuator, a relatively hard, nonmagnetic material is positioned between an inner surface of the stator that is made from a relatively soft, magnetic material and an outer surface of the push pin.Type: GrantFiled: February 21, 2003Date of Patent: November 1, 2005Assignee: Caterpillar Inc.Inventors: Clifford E.
