Abstract

A valve assembly with a valve body, which has a fluid passage designed as a fluid inlet and at least one fluid passage designed as a fluid outlet, is disclosed. A fluid chamber connecting the fluid inlet to the at least one fluid outlet is formed in the valve body. A movably mounted closing body is positioned in the fluid chamber. The closing body is guided axially and/or radially by at least one guide ball. The at least one guide ball is arranged between the closing body and a lateral delimitation of the fluid chamber. A fluid passage is formed in the radial direction of the valve body.

First claim

The invention claimed is:

1. A valve assembly, comprising:
a valve body having a fluid inlet passage and at least one fluid outlet passage, the valve body further having a fluid chamber configured to connect the fluid inlet passage to the at least one fluid outlet passage;
a closing body movably mounted in the fluid chamber; and
at least one guide ball arranged between the closing body and a lateral boundary of the fluid chamber, the at least one guide ball being configured to guide axial and/or radial movement of the closing body within the fluid chamber,

wherein:
the at least one fluid outlet passage is formed in the radial direction of the valve body, and
the at least one fluid outlet passage includes a plurality of fluid outlet passages which are each formed in the radial direction of the valve body, the plurality of fluid outlet passages configured such that fluid flows in parallel from the fluid chamber through the plurality of outlet passages.

2. The valve assembly as claimed in claim 1 , wherein the fluid inlet passage is formed in the axial direction of the valve body.

3. The valve assembly as claimed in claim 1 , wherein the valve body is formed from a plurality of sub-bodies.

4. The valve assembly as claimed in claim 3 , wherein the fluid outlet passage is formed between adjacent sub-bodies of the plurality of sub-bodies.

5. The valve assembly as claimed in claim 1 , wherein the plurality of fluid outlet passages are distributed in the circumferential direction of the valve body.

6. The valve assembly as claimed in claim 1 , wherein:
the at least one guide ball includes a plurality of guide balls arranged in the fluid chamber, and
the plurality of guide balls are held in place by a positioning structure.

7. The valve assembly as claimed in claim 6 , wherein:
the ball retainer includes the positioning structure,
the positioning structure defines a plurality of depressions, and
the plurality of depressions are configured to at least partially accommodate and position the plurality of guide balls, respectively.

8. The valve assembly as claimed in claim 6 , wherein:
the positioning structure defines axial retaining grooves which are defined in the valve body, and
the axial retaining grooves are configured to at least partially accommodate and position the plurality of guide balls, respectively.

9. The valve assembly as claimed in claim 1 , further comprising a return spring positioned in the fluid chamber, wherein:
the valve body further has a valve seat,
the return spring is configured to generate a preloading force which acts upon the closing body in the direction of the valve seat, and
to create an opening between the closing body and the valve seat, a fluid force is configured to act on the closing body counter to the preloading force.

10. The valve assembly as claimed in claim 9 , further comprising a ball retainer movably guidable in the fluid chamber, wherein:
the at least one guide ball is arranged on the ball retainer, and
the preloading force acts on the at least one guide ball via the ball retainer.

11. The valve assembly as claimed in claim 10 , wherein:
the ball retainer has at least one passage and/or at least one recess, and
the at least one passage and/or the at least one recess each form a flow cross section.

12. The valve assembly as claimed in claim 10 , further comprising a spring retainer positioned in the fluid chamber, wherein:
the return spring is supported at one end on the ball retainer and at the other end on the spring retainer.

13. The valve assembly as claimed in claim 12 , wherein the spring retainer is designed as an integrated component of the valve body.
