Abstract

An apparatus for handling fluid within an at least partially electrically driven vehicle, with a valve device including a valve housing. The valve housing includes at least three two radially arranged port openings and at least one axially arranged port opening for the inflow and/or outflow of fluid, and a valve body which is arranged inside the valve housing and is configured to be rotatable about an axial axis of rotation R. The valve body includes a first connecting channel of arcuate shape for connecting two radially arranged port openings and a second connecting channel of arcuate shape for connecting a radially arranged port opening with an axially arranged port opening. The at least two radially arranged port openings define a base plane B, which is configured orthogonally to the axial axis of rotation R, and the first arcuate connecting channel defines a first connecting channel plane V.

First claim

The invention claimed is:

1. An apparatus for handling fluid within an at least partially electrically powered vehicle, comprising:
a valve device including,
a valve housing, the valve housing having at least two radially arranged port openings and at least one axially arranged port opening for the inflow and/or outflow of fluid,
a valve body which is arranged inside the valve housing and which is configured to be rotatable about an axial axis of rotation (R), wherein
the valve body includes a first connecting channel of arcuate shape for connecting two radially arranged port openings and a second connecting channel of arcuate shape for connecting a radially arranged port opening to an axially arranged port opening,
wherein the at least two radially arranged port openings define a base plane (B) which is orthogonal to the axial axis of rotation (R), and the first arcuate connecting channel defines a first connecting channel plane (V),

wherein the first connecting channel plane (V) includes a first angle of inclination (α), which is greater than 0°, relative to the base plane (B).

2. The apparatus according to claim 1 , wherein the first angle of inclination (α) is smaller than 45°, in particular smaller than 30°, in particular smaller than 15°, in particular smaller than 5°.

3. The apparatus according to claim 1 , wherein a radially arranged port opening and an axially arranged port opening define an axial plane (A) and the second connecting channel of arcuate shape defines a second connecting channel plane (W), wherein the axial plane (A) includes a second angle of inclination (β) with respect to the second connecting channel plane (W) which is greater than 0°.

4. The apparatus ( 100 ) according to claim 3 , wherein the second angle of inclination (β) is smaller than 45°, in particular smaller than 30°, in particular smaller than 15°, in particular smaller than 5°.

5. The apparatus according to claim 1 , wherein the second connecting channel of arcuate shape for connecting a radially arranged port opening to an axially arranged port opening includes an additional connecting channel for connecting a second radially arranged port opening to the axially arranged port opening.

6. The apparatus according to claim 1 , wherein the valve body is configured as a sphere and includes a bearing which is arranged outside the valve body.

7. The apparatus according to claim 6 , wherein the bearing includes a bearing ring which is associated with the axial port opening.

8. The apparatus according to claim 1 , wherein a sealing element is associated with at least one port opening of the valve housing, wherein an inner diameter of a corresponding connecting channel is substantially identical to the inner diameter of the sealing element.

9. The apparatus according to claim 8 , wherein the sealing element includes Teflon.

10. The apparatus according to claim 1 , wherein the valve body includes at least a contour associated with the inlet and/or the outlet of the first connecting channel or the second connecting channel.

11. The apparatus according to claim 1 , further comprising: an apparatus housing with a first housing section and a second housing section, wherein the first housing section and the second housing section are configured to be adjacent to each other by a fluidically impermeable contour wall,
wherein the contour wall includes a side oriented toward the first housing section and a side oriented toward the second housing section,
at least one fluid handling element,
wherein the fluid handling element includes a first element arranged in the first housing section for generating a controllably variable magnetic field, and a second element in the form of the valve device movable by the generated magnetic field and which is arranged in the second housing section.

12. The apparatus according to claim 11 , wherein the first element includes a stator for generating a controllably variable magnetic field and the second element in the form of the valve device movable by the generated magnetic field in the form of the valve device includes a rotor.

13. The apparatus according to claim 11 , wherein the contour wall includes a cylindrical protrusion, which at least substantially fills an interior of a stator arranged in the first housing section.

14. The apparatus according to claim 13 , wherein the cylindrical protrusion is configured to accommodate a rotor arranged in the second housing section.

15. The apparatus according to claim 1 , wherein the apparatus includes a second fluid handling element including a fluid pump.

16. The apparatus according to claim 1 , wherein the rotor axes of the fluid handling elements are arranged parallel to each other.
