Definitions
- the present invention relates to a valve for a liquid system of the kind mentioned in the preamble of claim 1, a liquid tank for a liquid system, a liquid system of a vehicle and a vehicle.
- valves and liquid tanks for liquid systems, liquid systems and vehicles are already known from the prior art in numerous design variants.
- the known valves for fluid systems in vehicles include a valve housing with a plurality of valve housing openings, a valve body which is arranged in the valve housing so as to be rotatable about an axis of rotation and has at least one flow-conducting connection channel for the flow-conducting connection of at least two valve housing openings of the plurality of valve housing openings, one between the valve housing and the Valve seal arranged on the valve body with valve seal openings corresponding to the valve housing openings, a valve drive for automatic rotation of the valve body about the axis of rotation and a plurality of flow channels corresponding to the valve housing openings for flow-conducting connection of the valve to the remainder of the liquid system.
- the relevant flow channels known from the prior art usually have a circular inner contour and a circular outer contour in cross section.
- the object of the present invention is to improve a valve for a liquid system, a liquid tank for a liquid system, a liquid system of a vehicle and a vehicle.
- a valve for a liquid system of a vehicle with the features of claim 1 which is characterized in that the flow channels are formed together from a single first channel shell and a single second channel shell, the first channel shell being the valve housing at the same time is formed, which can be connected to form the flow channels with the second channel shell.
- a liquid tank for a liquid system of a vehicle having the features of claim 6 a liquid system of a vehicle having the features of claim 8 and a vehicle having the features of claim 10.
- the vehicle can be, for example, a land vehicle designed as a motor vehicle.
- a motor vehicle embodied as an electric vehicle or as a so-called hybrid vehicle may be mentioned here purely by way of example.
- the invention can also be advantageously used in other land vehicles as well as in air and sea vehicles.
- the valve according to the invention can preferably be a so-called multi-way valve. However, this is not necessarily the case.
- the dependent claims relate to advantageous developments of the invention.
- An essential advantage of the invention lies in the fact that a valve for a liquid system, a liquid tank for a liquid system, a liquid system of a vehicle and a vehicle are improved.

Furthermore, this enables the components of a fluid system for a vehicle to be centralized. At the same time, a flow-optimized shaping of the flow channels of the liquid system can easily be realized in terms of production technology. This, for example, among other things in that the invention makes it possible for the flow channels, in contrast to the prior art, to also have cross sections with non-circular inner contours.
- cross sections with essentially rectangular inner contours are conceivable, in which a clear width of the respective flow channel is greater than that of a cross section with a circular inner contour. Corners of a rectangular inner contour, for example, can be rounded for the purpose of additional optimization of the flow.
- valve according to the invention for a liquid system of a vehicle can be freely selected within wide suitable limits in terms of type, function, material, dimensioning and arrangement in the liquid system.
- This enables a particularly simple production and manufacture of the valve according to the invention. For example, this makes it possible to lay the flow channels in a manner that is particularly suitable for the respective individual case, in particular in a flow-optimized manner.
- curved courses of the flow channels in particular in sections of the flow channels on the valve housing side, can be produced without problems, for example by using slides moved obliquely to the axis of rotation of the valve body in valve housings designed as plastic injection molded parts.
- the aforementioned slides can be moved obliquely upwards or obliquely downwards, so that a curved course of the flow channel corresponding thereto can easily be realized in terms of production technology.
- valve housing and / or the valve body is/are designed to be moldable in such a way that a sealing side of the valve housing and/or the valve body facing the valve seal is designed essentially free of burrs after the valve housing and/or the valve body has been demolded.
- the valve seal and thus the valve according to the invention enable a long service life even without any complex post-processing of the aforementioned seal sides.
- This can be implemented in terms of manufacturing technology, for example, in such a way that a mold separation in the above-mentioned plastic injection molded part on the sealing side of the valve housing is structurally avoided.
- valve housing is designed as an integral part of a liquid tank of the liquid system, preferably a coolant tank of the vehicle for storing coolant carried in the liquid system designed as a coolant system.
- this reduces the number of components in the liquid system.
- the logistics, warehousing and manufacture of the fluid system for a vehicle are correspondingly simplified.
- this enables a very compact and thus space-saving design of the liquid system.
- a tank housing of the liquid tank is designed in multiple shells and has a plurality of tank housing shells, with the valve housing being designed at the same time as one of the tank housing shells of the tank housing, preferably that the valve housing is designed as a bottom tank housing shell of the tank housing.
- the tank housing of the liquid tank with the valve housing integrated therein can be realized in a manner that is particularly simple in terms of design and production technology.

- the liquid tank according to the invention for a liquid system of a vehicle can be freely selected within wide suitable limits in terms of type, function, material, dimensions and arrangement in the liquid system and on the vehicle, analogously to the valve according to the invention.
- an advantageous development of the liquid tank according to the invention for a liquid system of a vehicle provides that the tank housing is designed in multiple shells and has a plurality of tank housing shells, with one of the tank housing shells being designed at the same time as the valve housing, preferably that the Valve housing is designed as a bottom tank housing shell of the tank housing.
