Connector assemblies are provided for controlling flow in a fluid line that include an outer shell, an inner housing, and a tubular member. The inner housing is disposed within the outer shell and includes a boss disposed adjacent a first end of the outer shell. The inner housing is movable axially within the outer shell between first and second positions when a device is connected to the first end. The tubular member is carried by the inner housing and includes a fluid passage extending between a second end of the outer shell. The tubular member moves axially as the inner housing moves between the first and second positions, and cam features on the outer shell and the tubular member cause the tubular member to rotate as the inner housing moves between the first and second positions, thereby opening a fluid path between the fluid passage and the first end.

L'invention concerne des ensembles de liaison permettant de réguler l'écoulement dans une conduite de fluide comprenant un revêtement externe, un logement interne et un élément tubulaire. Le logement interne est disposé à l'intérieur du revêtement externe et comprend un bossage disposé de manière adjacente à une première extrémité du revêtement externe. Le logement interne est déplaçable axialement à l'intérieur du revêtement externe entre des première et seconde positions lorsqu'un dispositif est relié à la première extrémité. L'élément tubulaire est supporté par le logement interne et comprend un passage de fluide s'étendant entre une seconde extrémité du revêtement externe. L'élément tubulaire se déplace axialement lorsque le logement interne se déplace entre les première et seconde positions, et des dispositifs à came sur le revêtement externe et l'élément tubulaire amènent l'élément tubulaire à pivoter lorsque le logement interne se déplace entre les première et seconde positions, ouvrant ainsi un trajet de fluide entre le passage de fluide et la première extrémité.
