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 vane pump having an electric drive unit with a drive shaft, a pump chamber, a rotor arranged in the pump chamber so as to rotate about a rotational axis, and a driver that has at least one driver pin and is connected in a rotationally fixed manner to the drive shaft, wherein, in an operating state of the vane pump, the driver pin, by way of a contact surface of the driver pin designed as a section of a lateral surface, engages in a torque-transmitting manner with a contact surface of the rotor delimiting a rotor recess designed to correspond to the driver pin. In order to improve a vane pump, it is proposed that the contact surface of the rotor is designed and arranged in such a manner that the rotational axis lies in the contact surface when this contact surface is hypothetically extended toward the rotational axis.

Vane pump

A pump, in particular for a fluid circuit in a vehicle, for example a coolant pump with a multi-part housing which has a pump chamber and a motor chamber, wherein an impeller is disposed in the pump chamber which is driven by a rotor arranged in the motor chamber, and wherein the rotor has a rotor shaft and a rotor body through which the rotor shaft is guided, wherein the rotor has through holes, which interconnect a space of the motor chamber on a first side of the rotor and a space of the motor chamber on a second side of the rotor.

Pump, in particular for a fluid circuit in a vehicle

A pump, in particular for a fluid circuit in a vehicle, for example a coolant pump with a multi-part housing that has a pump chamber, wherein an impeller is arranged in the pump chamber, wherein the pump chamber is bounded by a pump housing and a further housing part of the multi-part housing, wherein the pump housing and the further housing part each have a flange surface that rest against one another, and wherein one of the two flange surfaces has at least one annular groove and the other of the two flange surfaces has at least one circumferential web which engages in the annular groove.

Pump, in particular for a liquid circuit in a vehicle

An apparatus for camshaft timing adjustment, having a drive disc and a hub rotationally supported relative to each other and defining a common rotational axis wherein the hub is arranged within the drive disc or vice versa, a vane being accommodated in an adjusting chamber defined by the drive disc and the hub and separating the adjusting chamber into a first sub-chamber and a second sub-chamber, wherein the vane is attached to the hub or the drive disc, a hydraulic pump having a high pressure pump chamber, a low pressure pump chamber and a pump for pumping a hydraulic fluid from the low pressure pump chamber to the high pressure pump chamber, each pump chamber being fluidly connected to the first sub-chamber and the second sub-chamber.

Apparatus for camshaft timing adjustment with built in pump

An arrangement of an electric vacuum pump, for example, in a vehicle, wherein a mounting element is provided on which the vacuum pump is installed, and wherein the vacuum pump comprises a pump chamber part and a motor part, and wherein a longitudinal axis extends through the pump chamber part and the motor part. According to the invention, the vacuum pump has a horizontal arrangement with respect to a gravitational direction, wherein the installation of the vacuum pump on the mounting element is limited to two mounting points, and wherein a center of gravity of the vacuum pump lies on a connection axis between the two mounting points.

Arrangement of an electric vacuum pump in a vehicle

An electric vacuum pump, in particular for arrangement in a vehicle, having an electric motor and a pump part, which can be driven by the electric motor, so that air can be drawn into the pump part from a suction connection and wherein air can be taken out of the pump part out of an outlet connection. A motor flange is provided on which the pump part rests, and the outlet connection is disposed on the motor flange. A receiving space is formed in the motor flange into which space the outlet connection opens, and a rubber-elastic insert part, which has a hollow inner region which communicates with the outlet connection, is accommodated in the receiving space. The insert part has at least one air guide opening via which air can flow from the pump part into the inner region.

Electric vacuum pump, in particular for arranging in a vehicle

An electric air-pump apparatus for motor vehicles has a mounting plate to which a housing of an electric motor and a pumping device are attached. A sound absorber is, formed by the mounting plate and a sound-absorber cap attached thereto, with the sound-absorber cap surrounding the pumping device. The sound-absorber cap is positioned on a first side of the mounting plate opposite from a second side of the mounting plate at which the electric motor is to be attached.
