Beschreibung
Zusammenfassung:	A fluid coupling element includes a body having a rear chamber and an intermediate chamber, a main valve movable to close a main passage between the rear and intermediate chambers, a forward valve movable to close a front orifice of the inner pipe under the action of a first spring, and a safety valve movable to close a secondary passage through the main valve between the rear and intermediate chambers. During coupling with a complementary coupling element, the forward valve moves a plunger that opens the safety valve before the main valve is opened. The coupling element includes a second spring, pushing the plunger back toward a forward position in which the main valve and the safety valve are closed, and the plunger abuts against the main valve or against the safety valve.
