Outlet connection for ventilation or air conditioning plant in vehicle

摘要

The outlet connection is for conducting away condensation water occurring in the plant and/or water penetrating via the fresh air feed. It comprises a pipe connection (2) which at its one end is connected with the fresh air system of the plant and at its other end is closable by a check valve. The outlet aperture closable by the check valve in relation to its main plane is parallel or slightly inclined to the longitudinal axis of the pipe connection, and the check valve is an integral part of the pipe connection or is formed on it or is directly fixed to it. The check valve is a flap valve (4), the flap (5) of which is activated by gravity and/or by spring force and/or by its own rigidity in closing the outlet aperture.
