  • Patent number: 10914270
    Abstract: A motor vehicle includes a liquid container for receiving an operating liquid, a cooling circuit for cooling a drive motor of the motor vehicle via a cooling liquid circulating in the cooling circuit, at least one heating coil arranged in the liquid container, the heating coil being operatively attached to the cooling circuit so that the cooling liquid is to flow through the heating coil and thereby heat the operating liquid, and a connection line operatively attached to the cooling circuit to thereby form a secondary circuit through which the cooling liquid is to flow, wherein the heating coil is arranged in the secondary circuit.
    Type: Grant

  • Patent number: 10807464
    Abstract: A filling device includes a filling pipe to extend into a liquid container for fluidic connection to the liquid container, a filling head operatively connected to the filling pipe, a venting pipe to vent the liquid container, the venting pipe having an open venting pipe section at an end thereof, and an indicator member configured to visually indicate a filling condition of the liquid container. During a filling sequence of the liquid container in a condition in which the liquid container is not full of liquid, the indicator member is to be impinged upon by outflowing air in the venting pipe at a force such that the indicator member assumes a first recognizable condition. During a filling sequence of the liquid container in a condition in which the liquid container is full of liquid, the indicator member is not impinged on by outflowing air in the venting pipe at a force such that the indicator member assumes a second recognizable condition.

  • Patent number: 10525822
    Abstract: A ventilation nipple configured to ventilate a tank component that is composed of a plastic material, a tank device that includes such a ventilation nipple, and a method for producing such a tank device. The ventilation nipple includes a ventilation opening and a flange body arranged in an annular manner around the ventilation opening. The flange body has a first annular collar and a second annular collar each configured for connection via a weld connection to the tank component. The first annular collar and the second annular collar are arranged coaxially with respect to each other and also with respect to the ventilation opening. The first annular collar and the second annular collar define an annular hollow space configured to receive a sealing agent and/or an adhesive between the first annular collar and the second annular collar.
