Abstract
A connection device for connecting a ventilating line to an intake air flow guide of an internal combustion engine, wherein the connection device has a non-return valve for preventing a flow from the intake air flow guide into the ventilating line. The connection device has at least one hole which is arranged upstream of the non-return valve and connects an interior chamber of the connection device to a surrounding area of the connection device.
Claims8
A connection device for connecting a ventilation line to a supply air flow guide of an internal combustion engine, comprising:
- a connection device body that forms an end of the ventilation line and is configured to be inserted into a receiving member on the air supply flow guide so as to connect the ventilation line to the supply air flow guide;
- a non-return valve for preventing a flow from the supply air flow guide into the ventilation line, wherein the non-return valve is arranged at a downstream end of the connection device body;
- and
- at least one hole which is arranged through the connection device body upstream of the non-return valve so as to connect an inner space of the connection device to an exterior environment of the connection device and to thereby form a defined leakage location that indicates an improper connection of the connection device to the ventilation line.
