Abstract (en)
[origin: EP1970541A1] The case (10) has an annular channel (18) pierced with an evacuation orifice (22) in which a drain (36) is mounted to evacuate a liquid e.g. fuel, from the channel. The drain is formed of a tubular cylindrical body (38), and has a wall (40) formed at an end of the body for fixation of the drain by setting in the orifice. The drain is made of a metal alloy having a thermal dilation coefficient that is higher than the thermal dilation coefficient of the case around the orifice.
