Solenoid with an armature

摘要

The invention refers to a solenoid which comprises at least one armature supported in an armature space. The armature space is encircled by a coil carrying a number of windings which can be loaded with current. The magnetic field generated when loaded with current moves the armature against the pole core. In the armature a rebounding tappet is supported moving. Its tappet front facing the pole core projects, when not electrified, over the front of the armature.

主权项

1. A solenoid, at least comprising one armature supported in an armature space, wherein the armature space is encircled by a coil carrying a number of windings which can be loaded with electric current, and the magnetic field generated when loaded with electric current moves the armature against a pole core, characterized in that in the armature a rebounding tappet is supported by a supporting bearing to move in an axial direction, such that the rebounding tappet is moveable relative to the armature, and in not electrified condition the distance between a front of the rebounding tappet and the pole core is smaller than the distance between a front of the armature and the pole core, and in the armature an elastic element for the rebounding tappet configured as a rebounding tappet spring is provided, which is compressed when, during loading with electric current, the armature moves towards the pole core and the front of the rebounding tappet is in contact with the pole core, and on the armature a pull-back spring for the armature is arranged, the effective direction of which is in opposite direction of the movement of the armature in the direction of the pole core, and wherein the rebounding tappet spring is designed stronger or weaker than the pull-back spring for the armature.
