An electromagnet and method for producing the electromagnet. The electromagnet is intended to maintain pretensioning force of fastening by a force acting on a yoke over intended operating time under changing operating temperatures. The yoke encloses an armature that is provided with a flange, which conducts magnetic flux from a housing to the armature, the housing being connected on the one hand to a flange of the yoke and on the other hand to a core flange in a material-bonding manner by welding. The electromagnet can be used for actuation of valves, couplings or other electromechanical adjusting elements.

Electromagnet and method of making the electromagnet

A modular system of reciprocating pumps is to be designed in such a way that any type of said reciprocating pumps can be economically assembled and tested on a flexible assembly device. The magnetic part is a pre-assembled subassembly that can be tested separately and is overmolded with plastic material; the connection point to the pump part has a given connecting contour that allows different types of pump parts of the modular system to be connected; and the pump part is a pre-assembled subassembly that can be tested for the displaced volume thereof. Feed pumps and metering pumps for fuels and aqueous reagents.

Electrohydraulic pilot control means () for a hydraulic device which can be a proportional directional valve, an adjusting pump or an adjusting motor, which pilot control means contains two proportionally acting pressure control valves () and is provided with a control block () which accommodates the hydraulic valve parts () in holes and to which the associated proportional magnets are flange-connected, wherein the proportional magnets have a common electrical plug connection () and wherein the two proportional magnets () are joined to form an assembly by being encapsulated with plastic, the said assembly being fastened to the control block () and, in this case, being precisely oriented relative to the valve components (), which are accommodated in the control block, by means of positioning aids which act perpendicular to the movement direction of armatures.

Object: Device comprising an electromagnet () and an actuating element () which is operated by said electromagnet and may be, for example, a valve or a clutch, wherein said components are connected to one another by means of threads () and (), with protection of functional spaces in the components or of elastomeric seals against damage and adverse effects on functioning by particles from the threads. Solution: The electromagnet-side thread () and actuating element-side thread () are axially adjacent in both directions of chambers () and () which are closed off on in each case the side which is averted from the threads by overlapping cylinder surfaces () and () on one side and also by further overlapping cylinder surfaces () and () on the other side. Application: Actuating elements which are operated by an electromagnet.
