Abstract

A valve device has a movement element, which is cylindrical at least in sections, and a guide element, which has a guide recess for guiding the movement element and is pressed into a valve housing. The guide element comprises a radially inner ring-like section and a radially outer ring-like section. The guide recess is arranged in the inner ring-like section. On its outer circumference, the outer ring-like section has a number of contact sections which are arranged distributed uniformly over the circumference and by means of which the outer ring-like section is pressed into the valve housing. The inner ring-like section is connected to the outer ring-like section via an identical number of connecting sections, which are arranged distributed uniformly in the circumferential direction, wherein, as viewed in the circumferential direction, the connecting sections are offset radially by an angle of 180 DEG/N in relation to the contact sections.

First claim

The invention claimed is:

1. A valve device comprising:
a valve housing;
a movement element; and
a guide element which defines a guide recess for guiding the movement element and which is press-fit in the valve housing,
wherein the guide element includes a radially inner annular portion and a radially outer annular portion,
wherein the guide recess is defined in the radially inner annular portion,
wherein the radially outer annular portion includes contact portions at an outer periphery thereof, and the contact portions are press-fit into the valve housing,
wherein the radially inner annular portion is connected to the radially outer annular portion by connection portions positioned so as to be offset in relation to the contact portions when viewed in a peripheral direction,
wherein flattened portions are defined between the contact portions on the outer periphery of the outer annular portion when viewed in the peripheral direction;
wherein the valve housing defines a continuous, circular inner surface; and
wherein the contact portions of the guide element are press-fit into the continuous, circular inner surface of the valve housing.

2. The valve device as claimed in claim 1 , wherein:
the radially outer portion includes a number N of contact portions positioned so as to be distributed over the outer periphery at least substantially uniformly, and
the connection portions are positioned so as to be offset by an angle of approximately 180°/N relative to the contact portions.

3. The valve device as claimed in claim 2 , wherein the quantity of connection portions is equal to or less than the number N of contact portions.

4. The valve device as claimed in claim 2 , wherein the radially outer portion includes three contact portions.

5. The valve device as claimed in, claim 1 , wherein recesses are defined between the connection portions when viewed in the peripheral direction.

6. The valve device as claimed in claim 5 , wherein the recesses are kidney-shaped.

7. The valve device as claimed in claim 1 ,
wherein the flattened portions each have a convex outer contour.

8. The valve device as claimed in claim 1 , wherein the guide element is produced in one piece.

9. The valve device as claimed in claim 1 , wherein the guide element is produced by one of stamping, a chip-removal method, and metal injection molding.

10. The valve device as claimed in claim 1 , wherein the valve device is used to switch fuel, hydraulic oil or brake fluid.

11. The valve device as claimed in claim 1 , wherein the flattened portions each have a concave outer contour.

12. The valve device as claimed in claim 1 , wherein:
the guide recess defines a central longitudinal axis; and
a radial distance between the longitudinal axis and each of the flattened portions is less than a radial distance between the longitudinal axis and each of the contact portions.
