The invention relates to a vent connection for liquid filling and ventilating in a hydraulic coupling disengagement system of a motor vehicle, comprising a ventilating valve and a pipe housing. Said ventilating valve is arranged so that it can rotate in the connection housing. Said ventilating valve is provided with primary sealing means and comprises, inside, a bore which can be closed by the primary sealing means and can be reopened by rotating the ventilating valve 180° in order to discharge air and liquids in the desired direction and according to requirements. Said vent connection also comprises secondary sealing means which are placed on the ventilating valve behind the bore in the direction of ventilation in order to reduce the incorrect positioning of the ventilating valve with respect to the connection housing and to reduce the risk of leakage between the ventilating valve and the connection housing which is connected thereto. |
