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.

Abstract: A filling adapter for a container to be filled with media, in particular for the filling of containers on assembly lines for the production of motor vehicles where the filling adapter is equipped with a hose pack, electrical, pneumatic, and hydraulic lines. The filling adapter has a barrel and a ball piece and is operatively connected to two media lines in a hose pack, wherein the media are redistributed in the adapter head, in which a filling valve and a vacuum valve are arranged, which are each connected to the barrel, and wherein an aeration line branches off from a vacuum line in the hose pack by means of a check valve and is connected to the ball piece.

Abstract: A filling adapter for a container to be filled with media, in particular for the filling of containers on assembly lines for the production of motor vehicles where the filling adapter is equipped with a hose pack, electrical, pneumatic, and hydraulic lines. The filling adapter is equipped with a clamping drive housing with a stationary part and a receiving part for clamping claws. The receiving part can be operatively connected with a union nut such that, after loosening the union nut, the position of the clamping claws can be rotationally adjusted, allowing rotation of the filling adapter with respect to the container to be filled. A clamping drive housing includes a toothing, with which the receiving part for the clamping claws engages by way of a locking pin.

Abstract: A filling adapter for a container to be filled with media, in particular for the filling of containers on assembly lines for the production of motor vehicles where the filling adapter is equipped with a hose packet, electrical, pneumatic, and hydraulic lines. A filling adapter according to the disclosure achieves better fluid flow properties while reducing the overall size, production costs, and weight of the filling adapter. The filling adapter is equipped with a coaxial valve in the region of the adapter head of the filling adapter, which coaxial valve, starting from the inlet cross section, is initially provided with a flow contour extending parallel to the longitudinal axis of the valve, which in the further flow course transitions into a flow contour extending at a right angle to the longitudinal axis of the valve to the outlet cross section.

Abstract: A filling adapter for a container to be filled with media, in particular for the filling of containers on assembly lines for the production of motor vehicles where the filling adapter is equipped with a hose pack, electrical, pneumatic, and hydraulic lines. An electronic assembly (ID chip) for a maintenance check is integrated in the adapter head of the filling adapter, which assembly detects the number of use cycles of the filling adapter and compares said number with parameters which can be set in advance in such a way that when said parameters are approached, at least one prior warning is triggered, and when said parameters are reached, an associated controller is informed about the maintenance which is now due.

Abstract: A filling adapter for a container to be filled with media, in particular for the filling of containers on assembly lines for the production of motor vehicles where the filling adapter is equipped with a hose pack, electrical, pneumatic, and hydraulic lines. An interface is configured for coupling a gripping element designed as a separate assembly on the filling adapter in the region of the adapter head, wherein the interface has mechanical and electrical connecting elements which are disposed in a common plane and can be coupled to mechanical and electrical connecting elements of the gripping element which are congruent therewith.

Abstract: The invention relates to a method for preventing and detecting coolant discharges from complex hydraulic systems. The aim of the invention is to configure such a method in such a way that this method in particular meets requirements for preventing/limiting the development of explosive atmospheres in working areas and for reducing measures from previously otherwise typical requirements for Ex zones. This aim is achieved in that a circuit carrying coolant is divided into small volumes that have stop valves and a relief valve, wherein a leak detection diagnosis can be carried out by means of a pressure sensor that can be integrated.

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.

Abstract: The invention relates to a device for filling vehicle air conditioning systems with refrigerant R744 in such a manner that it allows the calculation of mass deviations in line sections during filling with the refrigerant R744. An adapter hose assembly is configured such that it is segmented, wherein segmentation takes place by inserting several pairs of respectively separate temperature and pressure sensors for determining the respective density of the refrigerant in the adapter hose assembly. The device comprises a mass calculator for controlling the filling valve in accordance with a central correction calculation based on different density deviations determined using the pairs of respectively separate temperature and pressure sensors and also using the parameters of the mass measurement provided by the mass flow meter.
