Connection coupling
First Claim
1. A connection coupling for transferring gaseous and/or liquid fluids, especially for filling gas tanks of motor vehicles, comprising an inlet region which comprises an inlet valve and is connected with a supply line and a ventilation line and comprises a pressure compensation chamber and a ventilation valve, the connection coupling having a longitudinal axis, wherein the ventilation valve is formed by a sealing disk which can be moved in the axial direction of the connection coupling in a controlled manner towards the inlet valve and away from the same, and wherein the sealing disk comprises a pair of sealing surfaces generally facing in opposite directions, each of which is formed on an end of the sealing disk and lies generally normal to the longitudinal axis of the coupling, the sealing disk further comprising two abutment surfaces disposed between the pair of sealing surfaces, the two abutment surfaces being configured to limit movement of the sealing disk in both longitudinal directions.

Abstract
The aim of the invention is to provide a simple and compact design as well as a safe operation of a connection coupling (10) for transferring gaseous and/or liquid fluids, particularly for filling vehicle fuel tanks, comprising an inlet area (12), which is provided with an inlet valve (45), connected to a supply line (12′) and to a ventilating line (12″), and which has a pressure compensation space (44) and a ventilating valve (35). To this end, the invention provides that the ventilating valve (35) is formed by a sealing disc (24) that can be displaced in a controlled manner up to and away from the inlet valve (45) in an axial direction of the connection coupling (10).
