Edge-compressed tilting armature for a vehicle solenoid valve

A vehicle solenoid valve, comprising:

• at least one valve opening having a tilting armature, wherein the tilting armature includes:
• a ferromagnetic tilting armature for the vehicle solenoid valve which, by establishment of a magnetic field, is configured to move the tilting armature into one of two positions such that a magnetic flux, associated with the magnetic field, through the tilting armature is in the position conducted through at least one surface of the tilting armature across a gap to form a closed flux loop, wherein the tilting armature is tiltable between the two positions about an axis of rotation that is fixed with respect to the vehicle solenoid valve;
• wherein an enlargement of the at least one surface of the tilting armature by an edge upset of the tilting armature is configured to reduce a magnetic resistance through the gap,
• wherein the tilting armature is in the shape of a circular disk, above a surface of which heads of two spherical-cap joints and a spring fixture rise in relief, and
• wherein a surface of the tilting armature at the gap is enlarged by the edge upset of the tilting armature, so as to reduce a magnetic resistance of the gap, so as to promote a force with which the tilting armature is held in a position, and wherein the force that causes the tilting armature to be moved into the position is also increased.

A method for producing a tilting armature for a vehicle solenoid valve, the method comprising:

• clamping a tilting armature blank into an edge forming machine;
• and
• edge-upsetting the tilting armature blank to form a bulge of the tilting armature blank in an edge region, such that a tilting armature with an edge upset of predetermined size and shape is produced;
• wherein the tilting armature is tiltable between two positions about an axis of rotation that is fixed with respect to the vehicle solenoid valve,
• wherein the tilting armature is a ferromagnetic tilting armature for the vehicle solenoid valve which, by establishment of a magnetic field, is configured to move the tilting armature into one of the two positions such that a magnetic flux, associated with the magnetic field, through the tilting armature is in the position conducted through at least one surface of the tilting armature across a gap to form a closed flux loop, and
• wherein an enlargement of the at least one surface of the tilting armature by the edge upset of the tilting armature is configured to reduce a magnetic resistance through the gap,
• wherein the tilting armature is in the shape of a circular disk, above a surface of which heads of two spherical-cap joints and a spring fixture rise in relief, and
• wherein a surface of the tilting armature at a gap is enlarged by the edge upset of the tilting armature, so as to reduce a magnetic resistance of the gap, so as to promote a force with which the tilting armature is held in a position, and wherein the force that causes the tilting armature to be moved into the position is also increased.
