Abstract: A system for detecting dry running of a pump includes an inlet device to an intake device of the pump for taking in an electrically conductive liquid, and an electrical resistance structure (20) arranged in the inlet device. The electrical resistance structure has a variable resistance value, dependent on wetting with the electrically conductive liquid.

Abstract: A brushless direct current motor with a stator and rotor uses permanent magnets facing the stator and which are held in place by springs that urge the magnets toward the periphery of a support structure for the rotor.

Abstract: The present invention is a supplementary control valve device including a valve body, which may be reversibly displaced in a guide, in the direction of the longitudinal axis, between an opening solenoid and a closing solenoid. The magnetic yoke of the opening solenoid includes at least one extension, with direct contact with a web, connected to the guide on the end thereof facing away from the extension.

Abstract: The supplementary control valve device comprises a valve body, which may be reversibly displaced in a guide (3), in the direction of the longitudinal axis, between an opening solenoid (1) and a closing solenoid (2). The magnetic yoke (4) of the opening solenoid (1) comprises at least one extension (5), with direct contact with a web (6), connected to the guide (3) on the end thereof facing away from the extension (5).

Abstract: The present invention relates to an actuating device with an electromotive rotary drive, via which an actuating element can be driven rotatably about an axis of rotation between a first end position and a second end position and can be acted upon out of the first end position by a spring. The electromotive actuating drive includes a reversing drive and the spring action upon the actuating element is effective between the first end position and an intermediate position. The spring action is ineffective between the intermediate position and the second end position. The intermediate position lies between the first end position and the second end position.

Abstract: Electronic components are arranged outside of the cooling channel of a motor vehicle's engine.

Abstract: In an electric motor, one one bearing plate (4) is made of plastic. A heat dissipation plate (9) is arranged a short distance in front of that side of the bearing plate (4) which faces the interior of the electric motor. The heat dissipation plate (9) carries heat from a bearing (5) to an electric motor housing (6), which is made of metal. This allows the electric motor to be manufactured particularly cost-effectively.
