Abstract

A plate armature damping device for a tilting armature valve includes at least one damping body which can be fixed to a plate armature, with at least one damping material which, on an impact movement of the plate armature in the direction of a counter-element, is elastically deformable on impact on the counter-element. The at least one damping body has a geometric contour including at least one bulge on a surface of the at least one damping body facing the counter-element, which is configured such that, on the impact movement of the plate armature, the volume of the at least one damping body contributing to the damping increases.

First claim

What is claimed is:

1. A plate armature damping device for a tilting armature valve, comprising:
at least one damping body that is fixable to a plate armature, with at least one damping material which, on an impact movement of the plate armature in the direction of a counter-element, is elastically deformable on impact on the counter-element;
wherein the at least one damping body has a geometric contour having bulges on a surface of the at least one damping body facing the counter-element, which is configured such that, on the impact movement of the plate armature, the volume of the at least one damping body contributing to the damping increases, and
wherein each of the bulges extend along a curved linear extent of the at least one damping body, which is curved.

2. The plate armature damping device of claim 1 , wherein the bulges on the surface of the at least one damping body facing the counter-element is configured such that, during the impact movement of the plate armature, initially a first part of the damping material at the bulges is elastically deformed, and during the further course of the impact movement, a second part of the damping material, larger than the first part, is elastically deformed.

3. The plate armature damping device of claim 1 , wherein each of the bulges is arranged linearly along the surface of the at least one damping body, having a curved extent along the surface of the at least one damping body.

4. The plate armature damping device of claim 3 , wherein each of the bulges protrudes in the normal direction of the plate armature with a height which changes along the linear extent.

5. The plate armature damping device of claim 1 , wherein each of the bulges includes a first bulge and a second bulge which are arranged next to one another on a surface of the at least one damping body facing the counter-element and which are each configured such that, during the impact movement of the plate armature, initially a respective first part of the damping material at the first and second bulges is elastically deformed, and in the further course of the impact movement, a respective second part of the damping material, larger than the first part, is elastically deformed.

6. The plate armature damping device of claim 5 , wherein the first bulge protrudes in a normal direction of the plate armature with a first height and the second bulge protrudes in the normal direction of the plate armature with a second height which is smaller than the first height.

7. The plate armature damping device of claim 1 , further comprising:
a sealing body which is connected to the at least one damping body, wherein the sealing body is configured to close a valve opening fluid-tightly.

8. The plate armature damping device of claim 7 , wherein the sealing body and the at least one damping body are configured integrally.

9. The plate armature damping device of claim 7 , further comprising:
a retaining body configured to be anchored in the plate armature, and the at least one damping body and the sealing body are connected to the retaining body and configured such that they lie on opposite faces of the plate armature on fixing of the retaining body in the plate armature.

10. The plate armature damping device of claim 7 , wherein the sealing body and the at least one damping body are arranged offset to one another, viewed in the normal direction of the plate armature.

11. The plate armature damping device of claim 7 , wherein the at least one damping body includes a first damping body and a second damping body which are each arranged offset to the sealing body, viewed in the normal direction of the plate armature.

12. The plate armature damping device of claim 11 , wherein the first damping body and the second damping body are arranged offset on opposite sides of the sealing body.

13. The plate armature damping device of claim 1 , wherein each of the bulges is arranged linearly along the surface of the at least one damping body, having a curved, circular linear extent along the surface of the at least one damping body.

14. A plate armature for a tilting armature valve, comprising:
an armature body which can be mounted on the tilting armature valve by a bearing at an end face of the armature body and is movable from a first position into a second position by activation of an electric coil element; and
a plate armature damping device, which is arranged on a surface of the armature body so that, on an impact movement of the plate armature from the first position to the second position, the at least one damping body is elastically deformed on impact on the counter-element;
wherein the plate armature damping device, includes:
at least one damping body that is fixable to the plate armature, with at least one damping material which, on an impact movement of the plate armature in the direction of a counter-element, is elastically deformable on impact on the counter-element;
wherein the at least one damping body has a geometric contour having bulges on a surface of the at least one damping body facing the counter-element, which is configured such that, on the impact movement of the plate armature, the volume of the at least one damping body contributing to the damping increases, and
wherein each of the bulges extend along a curved linear extent of the at least one damping body, which is curved.

15. The plate armature of claim 14 , wherein the armature body has at least one first recess in which the at least one damping body is arranged at least along a partial extent of the damping body.

16. The plate armature of claim 15 , wherein the armature body has a second recess or opening, at which a sealing body is arranged on the surface of the armature body opposite the at least one damping body and is configured to close a valve opening of the tilting armature valve fluid-tightly, and wherein the at least one first recess and the second recess or opening are offset to one another in the normal direction of the armature body.

17. A tilting armature valve, comprising:
a plate armature, including:
an armature body, which is mountable on the tilting armature valve by a bearing at an end face of the armature body and which is movable from a first position into a second position by activation of an electric coil element; and
a plate armature damping device, which is arranged on a surface of the armature body so that, on an impact movement of the plate armature from the first position to the second position, the at least one damping body is elastically deformed on impact on the counter-element;
wherein the plate armature damping device, includes:
at least one damping body that is fixable to the plate armature, with at least one damping material which, on an impact movement of the plate armature in the direction of a counter-element, is elastically deformable on impact on the counter-element;
wherein the at least one damping body has a geometric contour having bulges on a surface of the at least one damping body facing the counter-element, which is configured such that, on the impact movement of the plate armature, the volume of the at least one damping body contributing to the damping increases, and
wherein each of the bulges extend along a curved linear extent of the at least one damping body, which is curved.

18. The tilting armature valve of claim 17 , wherein the tilting armature valve is for a pressure regulating module of a vehicle.
