An electronically commutated DC motor for a liquid pump, comprising a pump housing, a suction connection and a pressure connection, a substantially disk-shaped pump rotor mounted rotatably in the pump housing, the rotor comprising an impeller having a plurality of pump vanes and a permanent magnet, a partition separating a pump space from a dry space, wherein the partition is disposed in an axial gap between the pump rotor and a plurality of axially parallel oriented stator poles of the DC motor, which are each provided with an insulating body and a stator winding, the stator poles adjoin a stator yoke, which is connected to a metallic heat-conducting body, and the stator containing the stator poles, the stator windings, the stator yoke and the heat-conducting body is disposed in a motor housing made of plastic material. By providing that the stator is surrounded by a flexible foil, and at least a large part of the foil is disposed inside the motor housing radially around the stator windings, a simple solution ensures good shielding against interference in an existing electronically commutated DC motor, without requiring modifications to the existing design.

Electronically commutated DC motor for a liquid pump

A rearview mirror device for a vehicle. The mirror device includes a mirror base adapted to be fastened to the vehicle. A mirror head which includes a mirror is pivotable relative to the mirror base around the pivot axis. First contact surfaces are formed on the mirror head. Second contact surfaces are formed on the mirror base for cooperating with the first contact surfaces for limiting the pivotal rotation of the mirror head relative to the mirror base from at least a drive position to a parking position. A gear wheel is connected to the mirror base and arranged coaxially to the pivot axis. The gear wheel engages with a drive motor. A folding-path limiter is positioned between the mirror head and the mirror base for limiting the movement of the mirror head relative to the mirror base and a compression spring and a latching structure are used to connect the gear wheel to the mirror base. The mirror head is operative in at least three predetermined levels (A,B,C) as measured along the pivot axis relative to the mirror base. Level A is possible only between the drive position and the park position, and is defined by the latching structure found on the gear wheel and on the mirror base. Level B is defined by the mirror head and the mirror base. Finally, level C is defined by the latching structure on the mirror base and by the gear wheel or by the latching structure on the gear wheel and the mirror base.
