Abstract: The invention relates to an electric coolant pump for a coolant circuit of an internal combustion engine, having a radially accelerating pump impeller and a spiral housing section of a pump housing. A control circuit is arranged about an inlet on the side of the pump housing opposing the electric engine, and is accommodated in an ECU chamber. An open side of the pump chamber and an open side of the ECU chamber are separated by a heat-exchange cover, which is opened into the pump chamber at a mouth of the inlet, wherein a material from which the ECU chamber is made has a lower heat conductivity than a material from which the heat-exchange cover is made.

Abstract: A drive device for moving a covering element for covering an opening in a motor vehicle such as a roller blind, a baggage space cover or a sunroof cover, includes a drive, a guide device and a thrust element which is coupled to the drive. The thrust element is guided in the guide device and is connectable to the covering element in order to move the covering element. The drive for driving the thrust element is coupled to the thrust element via a transmission device being subjected to tensile stress, wherein the transmission device extends at least in certain sections in the guide device.
