  • Device for filling air-conditioning systems with a coolant in the final assembly of the vehicle
    Patent number: 10328767
    Abstract: A device for filling air conditioning systems with a refrigerant during final vehicle assembly, wherein the air conditioning system comprises a connection valve on its low and high pressure sides, via which the air conditioning system can be pressure tested, evacuated, and filled, which facilitates maintenance operations in the life cycle of the system, wherein said connection valves have different geometrical contours between the high and low pressure side and to ensure that only the respective approved refrigerant is filled into the air conditioning system, and wherein the filling is performed using a filling system brought via adapters into an operative connection with the connection valves on the low and high pressure sides. The device is designed to allow filling with two different refrigerants using just two adapters and still ensures that a proper refrigerant is filled into the respective air conditioning system.
