Abstract

An apparatus for handling fluid within an at least partially electrically powered vehicle, including: a valve device with a valve housing, the valve housing includes at least eight radially arranged port openings for fluid to flow in or out, a valve body, which is arranged inside the valve housing and is rotatable about an axis of rotation R, and the valve body includes at least four connecting channels for fluidly connecting two port openings, respectively.

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, wherein the valve housing comprises eight radially arranged port openings for fluid to flow in or out; and a valve body, which is arranged inside the valve housing and is rotatable about an axis of rotation R, wherein the valve body includes four connecting channels, each formed to fluidly connect two port openings of the eight radially arranged port openings, respectively, a further port opening of the eight port openings is arranged between two port openings that are fluidically connected to each other, and two port openings of the eight port openings that are arranged directly next to each other and have oval cross-sections are coupled directly to a heat exchanger.

2 . The apparatus according to claim 1 , wherein the valve body is configured to be transferable between at least four different switching positions.

3 . The apparatus according to claim 2 , wherein the radially arranged port openings each include the same distance from one another.

4 . The apparatus according to claim 1 , wherein the radially arranged port openings each include the same distance from one another.

5 . The apparatus according to claim 1 , wherein the port openings are located in a common port plane and the axis of rotation R is configured orthogonal to the port plane.

6 . The apparatus according to claim 1 , wherein the valve body includes a dividing wall which is configured to be parallel to the axis of rotation R.

7 . The apparatus according to claim 1 , wherein a wet-running gearbox is associated with the valve device.

8 . 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, wherein the apparatus further includes 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.

9 . The apparatus according to claim 8 , wherein the first element generating a controllably variable magnetic field includes a stator and the second element movable by the generated magnetic field in the form of the valve device includes a rotor.

10 . The apparatus according to claim 8 , wherein the contour wall includes a cylindrical protrusion, which at least substantially fills an interior of a stator arranged in the first housing section.

11 . The apparatus according to claim 10 , wherein the cylindrical protrusion is configured to accommodate a rotor arranged in the second housing section.

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

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

14 . An apparatus for handling fluid within an at least partially electrically powered vehicle, comprising:
a valve device including a valve housing, wherein the valve housing comprises eight radially arranged port openings for fluid to flow in or out; and a valve body, which is arranged inside the valve housing and is rotatable about an axis of rotation R, wherein the valve body includes four connecting channels, each connecting channel formed to fluidly connect two port openings of the eight radially arranged port openings, respectively, a further port opening of the eight port openings is arranged between two port openings that are fluidically connected to each other, two port openings of the eight port openings that are arranged directly next to each other are coupled directly to a heat exchanger, and the radially arranged port openings each include the same distance from one another.
