Abstract

The disclosure relates to a method for operating a filling adapter for filling refrigerant R744 into vehicle air conditioning systems as well as to a corresponding adapter. The adapter comprises mechanical clamping elements actuated by a pneumatically or mechanically controlled clamping piston. The clamping elements are clamped b the clamping system onto specifically designed sections of the vehicle air conditioning system for the filling process and are kept in the clamping position during the filling process. The clamping piston comprises at least two separate piston surfaces to be subjected to the pressure of two different pressurization media, one piston surface being effectively connected to the control pressure of the filling adapter and the other piston surface being effectively connected to the filling pressure of the refrigerant.
