Embodiment Construction

[0038] figure 1 A solenoid device for operating a solenoid valve is shown, comprising a solenoid coil 10 which defines a coil axis A and whose windings are accommodated by a coil bobbin 12 . In addition, a ferromagnetic circuit is shown, which is figure 1 It includes a fixed magnet housing, a movable armature 14 and a fixed opposite pole 16 of the armature. The magnet housing in this case has a top cover 18 , a bottom 20 and a housing 22 . Furthermore, a non-magnetic core guide 24 is provided, which extends within the solenoid coil 10 between the coil former 12 and the armature 14 or the opposite armature pole 16 . The electrical supply of the solenoid coil 10 is effected via an axially extending terminal 26 , which is also shown schematically.

[0039]On the solenoid coil 10 of the currentless switch, the armature 14 is typically loaded by a spring (not shown) such that the solenoid valve is in a desired position (open or closed). When the solenoid coil 10 is energized, a...

Abstract

An electromagnetic unit for a solenoid valve, has a magnetic coil and a ferromagnetic circuit surrounding the magnetic coil (10), which has a fixed magnet housing and a movable magnetic armature (14). The magnet housing is comprised of a cover (18), a wall (22) and a floor (20) in the form of multilayered transformer laminations. -

Description

technical field [0001] The invention relates to an electromagnetic device for a solenoid valve, comprising an electromagnetic coil and a ferromagnetic circuit surrounding the electromagnetic coil, which includes a fixed magnetic housing and a movable armature. Furthermore, the invention relates to a method for producing such an electromagnetic device and a method for producing a magnetic housing for such an electromagnetic device. Background technique [0002] The solenoid-operated valve has a solenoid coil, an armature for opening and closing the valve, and a magnet housing. In a simple constructional form, the magnet housing consists of a solid plate part bent in a U-shape. This construction is preferably suitable for direct current control. In AC control, this configuration produces a large amount of eddy current losses. As a result, the available power and the magnetic force are less, taking into account the permissible heating. Furthermore, it is known, for example,...
