  • Patent number: 10480836
    Abstract: Apparatus for filling an automobile air conditioning system with refrigerant in a liquid state is disclosed. R744 refrigerant is pumped in a liquid state from a storage tank to a refrigerant filling station having an inlet and two outlets. A first outlet is connected to a first refrigerant return line back to the storage tank. A second outlet is connected to an adapter for attaching to a service port of the air conditioning system during filling. An adapter support that has a connection port substantially the same as the service port receives the adapter when it is in a storage position. A valve is connected to the inlet and the first outlet and a temperature sensor measures a temperature of the refrigerant at the inlet. When the temperature is above a threshold, the valve closes the inlet and connects the refrigerant supply line to the first refrigerant return line.

  • Patent number: 10330546
    Abstract: A system for testing brake systems of motor vehicles at assembly lines of automobile manufacturers, wherein the brake pedal is operated using an automatically controlled device and wherein the pedal travel and pedal force are measured using associated instruments is disclosed. A travel-force curve is determined based on pedal travel and pedal force during pedal movement, which is analyzed using a physical brake system model. The brake system model isolates design influences of the individual components. Furthermore, the travel difference between different benchmarks of various vehicles is taken into consideration when calculating the pedal travel to compensate the variable influence of the running clearance on pedal travel.

  • Publication number: 20170227270
    Abstract: A device for filling vehicle air conditioning systems with refrigerant R744 comprises at least one storage tank for liquid refrigerant R744, actively connected by at least one pump station, a supply line and a return line to a filling system from which the refrigerant R744 is fed by an adapter into the vehicle air conditioning system. The refrigerant R744 is maintained in the liquid phase within the supply design. A temperature sensor and a valve circuit are arranged in the region between the supply line and the filling system, which control the flow of the refrigerant. Whenremoval of the refrigerant is interrupted, the refrigerant forcibly heated by the removal pause is returned and/or guided to the storage tank and the cold refrigerant is guided from the storage tank to the filling station. An adapter support in the support position can be tensioned by a sealing positive fit on a specific connection.
