Abstract

An electromagnetic actuator device with a plurality of actuator units ( 10, 12 ) having in each case an armature tappet which is movable relative to a stationary coil along an axial tappet direction when said coil is energised, said actuator units being received in respectively assigned actuator housings ( 11, 13 ) such that in an installed and/or assembled state of the electromagnetic actuator device one respective end portion ( 16 ) of the armature tappets may come into engagement in a controlled manner with an actuator partner which is able to be assigned thereto, wherein the plurality of actuator units is mechanically connected to a bracket-like and/or bridge-like connecting unit ( 14 ) made of polymer material such that the actuator housings are movable relative to one another by the action and in accordance with a predetermined bending property and/or elasticity of the connecting unit, in particular in a plane perpendicular to a tappet direction of the armature tappets which are further preferably guided in an axially parallel manner to one another.

First claim

The invention claimed is:

1. An electromagnetic actuator device with a plurality of actuator units ( 10 , 12 ) each comprising an armature tappet which is movable relative to stationary coil means along an axial tappet direction when said coil means are energised, said actuator units being received in respectively assigned actuator housings ( 11 , 13 ) such that in an installed and/or assembled state of the electromagnetic actuator device one respective end portion ( 16 ) of the armature tappets is engageable in a controlled manner with an actuator partner assigned thereto, wherein the plurality of actuator units is mechanically connected to a bracket-like and/or bridge-like connecting unit ( 14 ) made of polymer material, such that the actuator housings are movable relative to one another in accordance with a predetermined bending property and/or elasticity of the connecting unit, wherein the actuator housings are movable relative to one another in a plane perpendicular to a tappet direction of the armature tappets.

2. The device according to claim 1 , wherein the connecting unit is connected to the actuator housings by welding, bonding, encapsulating by injection-moulding or as a subassembly produced integrally with at least one of the actuator housings.

3. The device according to claim 1 further comprising a connection and/or plug unit ( 24 ) which is provided for energising the coil means of the plurality of actuator units together.

4. The device according to claim 3 , wherein the connection and/or plug unit ( 24 ) is integrally positioned on the connecting unit ( 14 ).

5. The device according to claim 3 , wherein the connection and/or plug unit ( 24 ) is produced from a polymer material.

6. The device according to claim 1 , wherein the connecting unit is configured such that electrical lines for energising the coil means run at least partially in or through the connecting unit ( 14 ).

7. The device according to claim 1 , wherein the connecting unit acts unreleasably on a lateral portion and/or on an outer portion of the actuator housings and/or has an extent parallel to an axial actuator direction which has less than 50% of a minimum extent of one of the actuator housings parallel to the axial actuator direction.

8. The device according to claim 7 , wherein the connecting unit has an extent parallel to the axial actuator direction which has less than 30% of a minimum extent of one of the actuator housings parallel to the axial actuator direction.

9. The device according to claim 7 , wherein the connecting unit has an extent parallel to the axial actuator direction which has less than 20% of a minimum extent of one of the actuator housings parallel to the axial actuator direction.

10. The device according to claim 1 , wherein grip, handling and/or flange portions ( 30 , 32 ) are assigned to a pair of adjacent actuator units on a front region of the respective actuator housing opposing a tappet outlet end, such that said portions define a minimum spacing of the actuator units as a spacing gap extending at least partially parallel, and permit a manual handling of the actuator device by access using one hand.

11. The device according to claim 10 , wherein the grip, handling and/or flange portions ( 30 , 32 ) are designed as a flange portion which is integrally formed on one respective actuator housing, which is flat and which projects radially from the actuator housing.

12. The device according to claim 10 wherein the grip, handling and/or flange portions ( 30 , 32 ) with one respective planar side on an end side determine a common end surface of the electromagnetic actuator device.

13. A use of the electromagnetic actuator device according to claim 1 , for assembly on an internal combustion engine of a motor vehicle for camshaft adjustment thereof.

14. The device according to claim 1 , wherein the actuator housings are guided in an axially parallel manner to one another.
