A device with a housing electrically conductive at least in regions, with an electrical circuit in the housing, with an electrically conductive connection between an electrically conductive region of the housing and the circuit, and with a holder made up of an insulator, which is arranged in the housing and to which at least parts and/or components of the electrical circuit are attached. At least one electrically conductive spring element, which is attached in or to the holder and which has a first end protruding beyond the holder and bearing against the housing with a spring force, is provided for establishing the electrically conductive connection between the electrically conductive region of the housing and the circuit.

Device comprising a housing, an electrical circuit in the housing, and an electrically conductive connection between the housing and the circuit

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.
