Abstract
A multiport valve for controlling a fluid flow in a fluid circuit, such as a cooling fluid circuit of a motor vehicle, may include a valve housing having at least three fluid connections and a rotary slide for setting the fluid flow. The rotary slide includes at least two fluid channels and is configured to connect two respective fluid connections fluidly via one fluid channel dependent upon its rotary position in relation to its rotational axis. The at least three fluid connections and the at least two fluid channels overlap in relation to a crosswise direction oriented crosswise relative to the rotational axis.
Claims20
A multiport valve for controlling a fluid flow in a fluid circuit, the multiport valve comprising:
- a valve housing having at least three fluid connections;
- and
- a rotary slide for setting the fluid flow arranged in the valve housing, the rotary slide comprising at least two fluid channels and being configured to connect two respective fluid connections fluidly via one fluid channel dependent upon its rotary position in relation to its rotational axis (R), wherein the at least three fluid connections and the at least two fluid channels overlap in relation to a crosswise direction oriented crosswise relative to the rotational axis (R);
- wherein the multiport valve has a first control state in which the rotary slide is aligned in relation to the valve housing such that a first fluid channel from the at least two fluid channels connects a first pair of fluid connections from the at least three fluid connections fluidly with one another and a fluid flow through a second fluid channel from the at least two fluid channels is prevented, and has a second control state in which a fluid flow through the first fluid channel is prevented and the second fluid channel connects a second pair of fluid connections from the at least three fluid connections fluidly with one another, further wherein each fluid channel is assigned to exactly one pair of fluid connections.
