Abstract

A fluid valve for influencing a fluid flow, including a valve housing in which an actuator is accommodated which can be moved between a first and a second functional position, further including a fluid passage which extends through some regions of the valve housing and terminates at a valve seat in the valve housing, and further including a sealing means which is motion-coupled to the actuator and designed for temporarily sealing the valve seat as a function of the functional position of the actuator, wherein a plastically deformable adjustment means is assigned to and designed to act on the actuator in order to allow a position of the sealing means to be adjusted in at least one of the functional positions of the actuator, the adjustment means being designed as a positionable abutment for the actuator or for a coupling element arranged between the actuator and the sealing means for the purpose of motion-coupling.

First claim

The invention claimed is:

1. A fluid valve for influencing a fluid flow, comprising a valve housing in which an actuator is accommodated which can be moved between a first and a second functional position, further comprising a fluid passage which extends through some regions of the valve housing and terminates at a valve seat in the valve housing, and further comprising a sealing means which is held on the actuator by adhesive force and is designed for temporarily sealing the valve seat as a function of the functional position of the actuator, wherein a plastically deformable adjustment means is assigned to and designed to act on the actuator in order to allow a position of the sealing means to be adjusted in at least one of the functional positions of the actuator, the adjustment means being designed as a positionable abutment for the actuator, and
wherein the adjustment means for altering a contact location for the abutment on the actuator is designed for a plastic deformation by means of an energy beam, and
wherein a shape change region is formed on the adjustment means, the shape change region changing the contact location for the abutment on the actuator if subjected to irradiation by an energy beam, and
wherein the shape change region is designed as a curvature region, and a curvature plane of the shape change region is oriented transverse relative to the movement plane.

2. The fluid valve according to claim 1 , wherein the adjustment means is supported on the valve housing between the actuator and a section of the valve housing.

3. The fluid valve according to claim 1 , wherein the energy beam is a laser beam.

4. The fluid valve according to claim 1 , wherein the actuator is designed as an electrically controllable bending element for a bending movement in a movement plane.

5. The fluid valve according to claim 4 , wherein the electrically controllable bending element is a piezoelectric bending element.

6. A fluid valve for influencing a fluid flow, comprising a valve housing in which an actuator is accommodated which can be moved between a first and a second functional position, further comprising a fluid passage which extends through some regions of the valve housing and terminates at a valve seat in the valve housing, and further comprising a sealing means which is held on the actuator by adhesive force and is designed for temporarily sealing the valve seat as a function of the functional position of the actuator, wherein a plastically deformable adjustment means is assigned to and designed to act on the actuator in order to allow a position of the sealing means to be adjusted in at least one of the functional positions of the actuator, the adjustment means being designed as a positionable abutment for the actuator, and
wherein the adjustment means for altering a contact location for the abutment on the actuator is designed for a plastic deformation by means of an energy beam, and
wherein a plurality of shape change regions are formed on the adjustment means, the plurality of shape change regions changing the contact location of the abutment in at least two different directions in space if subjected to irradiation by an energy beam, and
wherein the curvature planes of the shape change regions enclose an angle with one another, and
wherein the curvature planes of the shape change regions extend at right angles to one another.

7. The fluid valve according to claim 6 , wherein the adjustment means is located between the actuator and a section of the valve housing.

8. The fluid valve according to claim 6 , wherein the actuator is designed as an electrically controllable bending element for a bending movement in a movement plane.

9. The fluid valve according to claim 6 , wherein the energy beam is a laser beam.

10. The fluid valve according to claim 6 , wherein the electrically controllable bending element is a piezoelectric bending element.
