Abstract
The present disclosure relates to a valve device for a fluid flow. The device includes a housing with a fluid chamber delimited by an inner surface of the housing and with at least two ports opening into the fluid chamber. A valve slide is arranged rotatably about a rotation axis in the fluid chamber. The valve slide divides the fluid chamber into at least two fluid areas and bears against the inner surface, at least in sections, to seal the fluid areas with respect to one another. An actuation mechanism is arranged at least partially in the fluid chamber for rotating the valve slide.
Claims20
A valve device for a fluid flow, the valve device comprising:
- a housing with a fluid chamber delimited by an inner surface of the housing and with at least two ports opening into the fluid chamber,
- a valve slide arranged rotatably about a rotation axis in the fluid chamber, wherein the valve slide divides the fluid chamber into at least two fluid areas, and wherein the valve slide bears against the inner surface at least in sections to seal the fluid areas with respect to one another, and
- an actuation mechanism arranged at least partially in the fluid chamber for rotating the valve slide.
The valve device of claim 1,
- wherein the at least two ports open into the fluid chamber spaced apart from each other in a circumferential direction about the rotation axis, and
- wherein an angle between two ports adjacent in the circumferential direction about the rotation axis is at least 10 degrees and up to 170 degrees.
A thermal management system for an electrified vehicle, the thermal management system comprising:
- a valve device including:
- a housing with a fluid chamber delimited by an inner surface of the housing and with at least two ports opening into the fluid chamber,
- a valve slide arranged rotatably about a rotation axis in the fluid chamber, which valve slide divides the fluid chamber into at least two fluid areas, and which valve slide bears against the inner surface at least in sections to seal the fluid areas with respect to one another, and
- an actuation mechanism arranged at least partially in the fluid chamber for rotating the valve slide,
- at least one of a heat source and a heat sink, and
- a pump for providing a fluid flow,
- wherein the valve device is configured to supply the heat source or the heat sink with the fluid flow as a function of a temperature of the fluid flow.
A method for at least one of switching and mixing a fluid flow between multiple ports, the method including:
- directing the fluid flow through a valve device including:
- a housing with a fluid chamber delimited by an inner surface of the housing and with at least two ports opening into the fluid chamber,
- a valve slide arranged rotatably about a rotation axis in the fluid chamber, which valve slide divides the fluid chamber into at least two fluid areas, and which valve slide bears against the inner surface at least in sections to seal the fluid areas with respect to one another, and
- an actuation mechanism arranged at least partially in the fluid chamber for rotating the valve slide, and
- rotating the valve slide as a function of a temperature of a fluid flow, wherein the fluid flow includes a liquid.
