Abstract

Device for regulating and controlling a flow-through and distributing a fluid in a fluid circuit has a housing with ports connecting fluid lines that are connected across a passage aperture with an interior volume of the housing, a valve element disposed in the interior volume of the housing, a drive element for moving the valve element relative to the housing.

First claim

What is claimed:

1. A device for regulating and controlling a flow-through, and distributing a fluid in a fluid circuit, comprising a housing with ports for connecting with fluid lines that are in each instance connected across a passage within an interior volume of the housing as well as a valve element disposed in the interior volume of the housing with a drive element for moving the valve element relative to the housing wherein the valve element is supported rotatably about an axis of rotation and comprises openings that extend into an interior of the valve element as through-holes and form in the interior of the valve element a common volume,
wherein an axis of symmetry of at least one through-hole of a first opening and the axis of rotation of the valve element as well as an axis of symmetry of a passage within the interior of a first port of the housing are disposed in a direction z,
wherein axes of symmetry of through-holes of at least three openings of the valve element and of passages within each of two respective ports of the housing are disposed in a plane spanned by two directions x, y,
wherein the directions x, y, z are each oriented perpendicularly to one another; and
wherein a cover element with at least two outlet openings is positioned in the housing, wherein the cover element covers a flow cross section of the passage of the first port of the housing in a first position and opens the flow cross section of the passage of the first port in a second position.

2. A device as in claim 1 , wherein the axes of symmetry of the passages of the ports of the housing and the axis of rotation of the valve element have a common point of intersection in which the valve element is disposed with its center point.

3. A device as in claim 2 , wherein the outlet openings in each instance have a circular flow cross section and are disposed with their center points on a common reference circle diameter referred to a projected center point of a spherical shell.

4. A device as in claim 3 , wherein the diameters of the outlet openings are in each instance greater than or equal to the diameter of a through-hole of the first opening of the valve element.

5. A device as in claim 3 , wherein a first outlet opening and a second outlet opening, disposed adjacently to the first outlet opening, are developed at an angle of 90° referred to the projected center point of the spherical shell.

6. A device as in claim 1 , wherein the first port of the housing is disposed on a side of the valve element opposite to the drive element and wherein a second port and a third port are positioned on sides of the housing opposite to one another.

7. A device as in claim 1 , wherein the axes of symmetry of the passages provided in the interior of a second port and of a third port of the housing are disposed on a common axis oriented in the y-direction.

8. A device as in claim 1 , wherein the axes of symmetry of the passages of the first port, of a second port, as well as of a third port of the housing are positioned in a plane spanned by the directions y, z in the form of a T with respect to one another.

9. A device as in claim 1 , wherein the axis of symmetry of the passages of the first port of the housing and the axis of rotation of the valve element are disposed such that they are oriented coaxially with one another.

10. A device as in claim 1 , wherein the valve element is spherical.

11. A device as in claim 1 , wherein the axes of symmetry of the at least three openings, disposed in the plane spanned by two directions x, y, of valve element have a common point of intersection in the center of the valve element.

12. A device as in claim 1 , wherein the axis of rotation of the valve element is disposed such that it extends through the center of the valve element.

13. A device as in claim 1 , wherein the axis of symmetry of the at least one through-hole of the first opening is disposed such that it is oriented spaced apart from the axis of rotation of the valve element.

14. A device as in claim 1 , wherein the axes of symmetry of three of the openings, disposed in the plane spanned by two directions x, y, of the valve element are in the form of a T with respect to one another, wherein the axes of symmetry of a second opening and of a third opening as well as of the third opening and a fourth opening are each oriented orthogonally to one another, wherein the axes of symmetry of the second opening and of the fourth opening are disposed such that they are oriented coaxially with one another.

15. A device as in claim 14 , wherein the axes of symmetry of a through-hole of the first opening and of the second opening of the valve element are oriented such that they intersect, wherein the axis of symmetry of the first through-hole of the first opening is disposed offset from the center of the valve element in the direction of the fourth opening.

16. A device as in claim 1 , wherein the first opening of the valve element is developed with a first through-hole and a second through-hole of at least two through-holes.

17. A device as in claim 16 , wherein the axes of symmetry of the through-holes of the first opening are disposed on a common reference circle diameter referred to the axis of rotation of the valve element.

18. A device as in claim 17 , wherein the axes of symmetry of the through-holes of the first opening are disposed such that they are offset at an angle of 90° about the axis of rotation of the valve element as well as being disposed parallel to one another.

19. A device as in claim 16 , wherein the axes of symmetry of the second through-hole of the first opening and of the third opening of the valve element are oriented such that they intersect, wherein the axis of symmetry of the second through-hole of the first opening is disposed offset from the center of the valve element in the direction of the third opening.

20. A device as in claim 1 , wherein the at least one through-hole of the first opening of the valve element is developed on a side that is opposite to the side oriented to the drive element.

21. A device as in claim 1 , wherein the at least one through-hole of the first opening of the valve element has a diameter, wherein the diameter of the through-hole of the first opening is equal to or less than the diameter of the openings disposed in the plane spanned by the directions x, y, of the valve element.

22. A device as in claim 1 , wherein the outlet openings in each instance have a circular flow cross section and are disposed with their center points on a common reference circle diameter referred to a projected center point of a spherical shell.

23. A device as in claim 1 , wherein the cover element is a uniform segment of a spherical shell with constant wall thickness, also termed face, is disposed between the valve element and the housing, and a contour of an inner surface of the spherical shell corresponds to a contour of an outer surface of the spherical valve element.

24. A device comprising:
