Abstract

A valve for a liquid system of a vehicle having a valve housing with a multiplicity of valve housing openings, a valve body that is arranged in the valve housing so as to be rotatable about a rotational axis and has at least one flow-conducting connecting passage for the flow-conducting connection of at least two valve housing openings of the multiplicity of valve housing openings. A valve seal is arranged between the valve housing and the valve body. A valve actuator rotates the valve body about the rotational axis, and a multiplicity of flow passages corresponding to the valve housing openings for the flow-conducting connection of the valve to a remainder of the liquid system, are provided. The flow passages are jointly formed from a single first passage shell and a single second passage shell. The first passage shell is simultaneously formed as the valve housing.

First claim

What is claimed is:

1. A valve for a liquid system of a vehicle, the valve comprising:
a valve housing with at least two valve housing openings;
a valve body arranged in the valve housing so as to be rotatable about a rotational axis;
at least one flow-conducting connecting passage for a flow-conducting connection of at least two valve housing openings of the at least two valve housing openings;
a valve seal arranged between the valve housing and the valve body and has valve seal openings corresponding to the valve housing openings;
a valve actuator for automatically rotating the valve body about the rotational axis; and
at least two flow passages corresponding to the valve housing openings for a flow-conducting connection of the valve to a remainder of the liquid system,
wherein the at least two flow passages are jointly formed from a single first passage shell and a single second passage shell, and
wherein the single first passage shell is formed as the valve housing, which is joined to the single second passage shell to form the at least two flow passages.

2. The valve according to claim 1 , wherein the at least two flow passages on a valve housing side are designed to extend obliquely upward or downward at an angle to the rotational axis of greater than 0° and less than 90°.

3. The valve according to claim 1 , wherein the valve housing and/or the valve body are designed to be moldable in such a manner that a seal side of the valve housing and/or of the valve body that faces the valve seal is designed to be essentially flash-free after a demolding of the valve housing and/or of the valve body.

4. The valve according to claim 1 , wherein the valve housing is designed as an integral part of a liquid tank of the liquid system or a coolant tank of the vehicle for storage of coolant carried in the liquid system designed as a coolant system.

5. The valve according to claim 4 , wherein a tank housing of the liquid tank is designed as multiple shells and has a plurality of tank housing shells, wherein the valve housing is a bottommost tank housing shell of the tank housing shells of the tank housing.

6. A liquid tank for a liquid system of a vehicle, the liquid tank comprising:
a tank housing for storage of a liquid of the vehicle, wherein the tank housing is simultaneously designed as a valve housing for a valve for the liquid system of the vehicle, and
wherein the valve is designed according to claim 1 .

7. The liquid tank according to claim 6 , wherein the tank housing is designed as multiple shells and has a plurality of tank housing shells, wherein the valve housing is a bottommost tank housing shell of the tank housing shells of the tank housing.

8. A liquid system of a vehicle, comprising:
a liquid tank for storage of a liquid of the liquid system;
at least one liquid circuit, in which the liquid circulates, connected in a flow-conducting manner to the liquid tank; and
the valve according to claim 1 connected in a flow-conducting manner to the liquid circuit and/or to the liquid tank for controlling at least one liquid flow of the liquid in the liquid system.

9. The liquid system according to claim 8 , wherein the liquid tank is designed as a tank housing for storage of the liquid of the vehicle, and wherein the tank housing is simultaneously designed as the valve housing for the valve or wherein the tank housing is designed as multiple shells and has a plurality of tank housing shells, wherein the valve housing is a bottommost tank housing shell of the tank housing shells of the tank housing.

10. A vehicle comprising the liquid system according to claim 8 , wherein the liquid system is a coolant system of the vehicle.

11. The valve according to claim 1 , wherein the at least two flow passages on a valve housing side are designed to extend obliquely upward or downward at an angle to the rotational axis of 30° to 60°.

12. The valve according to claim 1 , wherein the single first passage shell is joined to the single second passage shell to form the at least two flow passages, such that a portion of a circumference of each of the at least two flow passages is formed by the single first passage shell and another portion of the circumference of each of the at least two flow passages is formed by the single second passage shell, and wherein seams are provided along each of the at least two flow passages at the joining of the single first passage shell and the single second passage shell.
