A multi-way valve for a motor vehicle, having a housing, in which a lower and upper chamber are disposed one above the other along an axis of rotation and are separated from each other by a separating wall. A lower valve body is disposed in the lower chamber for rotation about the axis of rotation. An upper valve body is disposed in the upper chamber for rotation about the axis of rotation. A drive shaft drives the lower and upper valve bodies. The drive shaft is torque-transmittingly connected to one of the two valve bodies and said valve body is torque-transmittingly connected to the other of the two valve bodies. A checking device checks for a correct alignment, and, in the event of an incorrect relative alignment of the two valve bodies in the peripheral direction, a reaction to the incorrect alignment can be automatically triggered.

Multi-way valve for a motor vehicle and method for operating a multi-way valve for a motor vehicle

A radial continuous-flow machine with cooling and lubrication by means of a medium flowing through the machine, wherein the medium flows from a high-pressure side to a low-pressure side of the radial continuous-flow machine, having a housing assembly and a rotor assembly that is rotatably mounted in an interior of the housing assembly, wherein at least one first bearing is provided for mounting the rotor assembly in the housing assembly, wherein the rotor assembly includes a rotor of an electric motor and an impeller, wherein the motor includes, in addition to the rotor, a stator that is a part of the housing assembly, wherein the rotor of the motor is arranged in a first region of the rotor assembly, and the stator is arranged in a first region of the housing assembly, wherein the first region of the housing assembly encloses the first region of the rotor assembly.

Radial continuous-flow machine with cooling and lubrication by way of a medium which flows through the machine

A pump device, in particular for a fluid circuit in a motor vehicle, comprising a housing, a drive, a rotor, a stator and a radial bearing, wherein the housing has an inlet, wherein the rotor comprises an impeller wheel, wherein the drive is designed to set the rotor in rotation relative to the stator, wherein the inlet is fluidly connected to the impeller wheel, wherein the rotor has a rotor cavity, wherein a section of the stator projects into the rotor cavity, and wherein the radial bearing is situated in the rotor cavity between the section of the stator and the rotor.

Pump device comprising a radial bearing

A pump device, in particular for a fluid circuit in a motor vehicle, comprising a stator, which has a stator core and a main body, and a rotor, wherein the rotor can be set in rotation relative to the stator, wherein the stator core is enclosed by the main body in a fluid-tight manner, and wherein the main body comprises a thermoset and a thermoplastic.

Pump device

A valve for a fluid system of a vehicle having a valve housing having a plurality of valve housing openings, a valve body arranged in the valve housing so as to be rotatable about an axis of rotation and having at least one flow-conducting connecting channel for the flow-conducting connection of at least two valve housing openings of the plurality of valve housing openings, a valve seal, arranged between the valve housing and the valve body and having valve seal openings corresponding to the valve housing openings, a valve drive for the automatic rotation of the valve body about the axis of rotation, and a plurality of connecting pieces, corresponding to the valve housing openings, for the flow-conducting connection of the valve to the rest of fluid system.

Valve for a fluid system and fluid system for a vehicle

A valve for a liquid system of a vehicle having a valve housing with a multiplicity of valve housing openings, a valve body that is arranged in the valve housing so as to be rotatable about a rotational axis and has at least one flow-conducting connecting passage for the flow-conducting connection of at least two valve housing openings of the multiplicity of valve housing openings. A valve seal is arranged between the valve housing and the valve body. A valve actuator rotates the valve body about the rotational axis, and a multiplicity of flow passages corresponding to the valve housing openings for the flow-conducting connection of the valve to a remainder of the liquid system, are provided. The flow passages are jointly formed from a single first passage shell and a single second passage shell. The first passage shell is simultaneously formed as the valve housing.

Valve and liquid tank for a liquid system, liquid system for a vehicle, and vehicle

A valve for a fluid system of a vehicle having a valve housing with valve housing openings, a valve body arranged so as to be rotatable about an axis of rotation, a valve seal, a valve drive, and a plurality of connecting pieces corresponding to the valve housing openings. The connecting pieces have a circular flow passage area in cross section at a free end of the respective connecting piece, and the valve housing openings, corresponding to the connecting pieces, each have a substantially rectangular cross section. The respective valve housing opening is larger than the flow passage area at the free end of the corresponding connecting piece, and the flow passage areas of the connecting pieces widen in a diffuser-like manner from the free end of the respective connecting piece to the respective corresponding valve housing opening and merge in a stepless manner into the respective valve housing opening.
