Apparatus for guiding air toward a wheel brake of a motor vehicle. The apparatus includes an air guide element, which can be displaced between a retracted rest position, in which the same is retracted in relation to an undercarriage of the motor vehicle, and an extended operating position, in which the same is extended in relation to the undercarriage. The air guide element can be displaced, via a hydraulic adjustment mechanism between the rest position and the operating position. The hydraulic adjustment mechanism includes a hydraulic cylinder and a return element. In the presence of brake actuation, the hydraulic cylinder can be filled with brake fluid in order to displace the air guide element from the rest position to the operating position. In the absence of brake actuation, the return element displaces the air guide element from the operating position to the rest position.

Apparatus for guiding air toward a wheel brake of a motor vehicle

A multi-valve for distributing at least one fluid, includes a plurality of input channels for supplying a respective fluid, a plurality of output channels for discharging the fluid, wherein a respective input channel can be connected via a plurality of input branches to a respective, substantially coaxially arranged output branch of the respective different output channels, and a switch plate which is arranged in a gap between the input branches and output branches and can be translationally moved transversely to the input branches and output branches in order to open and/or close a connection of the respective input branch to the respectively assigned output branch, wherein the switch plate is connected to an endless belt.

Space-saving multi-valve and method of operating a multi-valve

A multi-valve for a cooling system of a motor vehicle includes: a valve housing, which has a plurality of inlets and a plurality of outlets and delimits a cylindrical valve chamber, the plurality of inlets and the plurality of outlets opening into the cylindrical valve chamber; and a valve unit, which is arranged inside the cylindrical valve chamber of the valve housing and is rotatable about an axis of rotation between a plurality of switching positions by an actuator. Depending on a switching position of the valve unit, different inlets of the plurality of inlets are fluidically connectable to different outlets of the plurality of outlets. The valve unit has a plurality of fluid channel structures which are offset from one another in a circumferential direction. Each switching position of the plurality of switching positions is respectively assigned a fluid channel structure of the plurality of fluid channel structures.
