Abstract

An actuator ( 1 ) including at least one electromagnet ( 121, 122, 13, 14, 16, 17, 181, 182, 19, a magnet housing ( 11 ), at least one thrust pin ( 24 ) and at least one movable armature ( 14 ) with a respective plunger ( 16 ) that is movable in an axial direction is provided. When the at least one electromagnet ( 10 ) is energized, an axial movement of the at least one armature ( 14 ) can be transmitted via the at least one plunger ( 16 ) to the at least one thrust pin ( 24 ). At least one lever ( 30 ) is provided which is pivotably mounted on one side in the magnet housing ( 11 ) and with which at least one plunger ( 16 ) and the at least one thrust pin ( 24 ) are operatively connected such that the axial movement of the at least one plunger ( 16 ) can be transmitted to the at least one thrust pin ( 24 ).

First claim

What is claimed is:

1 - 8 . (canceled)

9 . An actuator comprising:
at least one electromagnet; a magnet housing; at least one thrust pin; at least one movable armature having a plunger movable in an axial direction, an axial movement of the at least one armature being transmittable to the at least one thrust pin via the at least one plunger when the at least one electromagnet is energized; and at least one lever supported pivotably to one side in the magnet housing and operatively connected to the at least one plunger and the at least one thrust pin in such a way that the axial movement of the at least one plunger is transmittable to the at least one thrust pin.

10 . The actuator as recited in claim 9 wherein the at least one plunger and the thrust pin assigned to the at least one plunger are situated in a parallel misalignment with respect to each other.

11 . The actuator as recited in claim 9 wherein the at least one lever includes: a first lever end supported pivotably around a bearing of the magnet housing; a second lever end abutting against a first end of the at least one thrust pin; and a support area situated between the first lever end and the second lever end and operatively connected to the at least one plunger.

12 . The actuator as recited in claim 11 wherein the bearing for the first lever end is a pin or a cylinder half, and the first lever end is supported in a frictional or antifrictional manner.

13 . The actuator as recited in claim 11 wherein the at least one lever is a formed lever, and wherein the second lever end has a convex indentation, or the first end of the thrust pin has a convex elevation, or the support area of the lever is formed as a trough-like indentation.

14 . The actuator as recited in claim 13 wherein the lever is a bent or stamped lever.

15 . The actuator as recited in claim 11 wherein a stroke of the thrust pin is adjustable with the aid of the location of the support area.

16 . The actuator as recited in claim 15 wherein a length of the stroke of the thrust pin, predefined by the lever, is equal to or greater than the length of the stroke of the armature.

17 . The actuator as recited in claim 16 wherein the length of the stroke of the thrust pin is twice the length of the stroke of the armature.
