Valve control device () for a coolant circuit of a motor vehicle, said valve control device () comprising a first valve () having an assigned first functional element () comprising a first engagement unit (), a second valve () having an assigned second functional element () comprising a second engagement unit (), wherein the first valve () and the second valve () in terms of the switch position thereof are configured so as to be variable by rotating the respective assigned functional element (), a locking mechanism () comprising an entrainment installation ( ), wherein the locking mechanism () is configured so as to be able to be driven by means of a drive (), wherein the locking mechanism () in a rotating movement, by means of the entrainment installation () engaging in the first engagement unit (), is configured for transferring the first functional element () from a first switch position to a second switch position, and/or, by means of the entrainment installation () engaging in the second engagement unit (), is configured for transferring the second functional element () from a first switch position to a second switch position, and wherein the engagement unit () of the first functional element () comprises a first number of engagement contours (), and the engagement unit () of the second functional element () comprises a second number of engagement contours (), wherein the first number differs from the second number.

Valve control device for a coolant circuit of a motor vehicle

This disclosure sets out an apparatus for handling fluid, such as coolant, for a vehicle that is at least partially powered by electricity. The apparatus includes a substantially plate-shaped base element defining a base plane separating a first subspace from a second subspace. At least a first fluid flow channel section is also present and is largely located in the first subspace. At least one second fluid flow channel section is also present and is largely located in the second subspace. The base element includes at least one first flow-through opening fluidly connecting the first fluid flow channel section and the second fluid flow channel section. A method of manufacturing the apparatus is also disclosed. The method includes the steps of providing the base element with at least a first fluid flow channel section and a first flow-through opening.

Apparatus for handling fluid of an at least partially electrically driven vehicle

The invention relates to a drive device for activating a rotary slide for a fluid system of an at least in part electrically operated motor vehicle. The drive device comprises an electric motor having a motor output shaft, a rotary slide output shaft configured for activating a rotary slide, wherein the rotary slide output shaft is aligned so as to be orthogonal to the motor output shaft, and a magnet is disposed on an end region of the rotary slide output shaft, and a sensor unit which is configured for detecting a rotary position of the magnet and thus of the rotary slide output shaft.

Drive device for activating a rotary slide

An apparatus for handling fluid within an at least partially electrically powered vehicle, with a rotary sliding valve arrangement, including a setting element rotatably arranged about a central axis, a rotary sliding valve wall, the setting element is arranged within and rotatable relative to the rotary sliding valve wall, and the rotary sliding valve wall includes inlet and outlet openings arranged in a first plane and in a second plane.

An apparatus for handling fluid within an at least partially electrically powered vehicle, with: an apparatus housing including a first housing section and a second housing section. The first housing section and the second housing section are adjacent to each other by a fluidically impermeable contour wall. The contour wall includes a side oriented toward the first housing section and a side oriented toward the second housing section, a first fluid handling element and a second fluid handling element. The first fluid handling element and the second fluid handling element include a first element for generating a controllably variable magnetic field arranged in the first housing section, and a second element movable by the generated magnetic field and arranged in the second housing section. The fluidically impermeable contour wall is continuously configured between the first fluid handling element and the second fluid handling element.

An apparatus for handling fluid within an at least partially electrically powered vehicle, with a pump device including a first running wheel and a second running wheel arranged coaxially with respect to each other and configured as a pump for conveying fluid by rotation.

An apparatus for handling fluid within an at least partially electrically driven vehicle, with a valve device including a valve housing. The valve housing includes at least three two radially arranged port openings and at least one axially arranged port opening for the inflow and/or outflow of fluid, and a valve body which is arranged inside the valve housing and is configured to be rotatable about an axial axis of rotation R. The valve body includes a first connecting channel of arcuate shape for connecting two radially arranged port openings and a second connecting channel of arcuate shape for connecting a radially arranged port opening with an axially arranged port opening. The at least two radially arranged port openings define a base plane B, which is configured orthogonally to the axial axis of rotation R, and the first arcuate connecting channel defines a first connecting channel plane V.
