CA 2717754

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 raccord fournis pour commander un écoulement dans une ligne de fluide, qui comprennent une enveloppe extérieure, un boîtier intérieur, et un élément tubulaire. Le boîtier intérieur est disposé dans l'enveloppe extérieure et comprend un bossage disposé de manière adjacente à une première extrémité de l'enveloppe extérieure. Le boîtier intérieur est axialement mobile dans l'enveloppe extérieure entre une première et une seconde position lorsqu'un dispositif est raccordé à la première extrémité. L'élément tubulaire est supporté par le boîtier intérieur et comprend un passage de fluide s'étendant entre le boîtier et une seconde extrémité de l'enveloppe extérieure. L'élément tubulaire se déplace axialement lorsque le boîtier intérieur se déplace entre les première et seconde positions, et des caractéristiques de came situées sur l'enveloppe extérieure et l'élément tubulaire amènent l'élément tubulaire à tourner lorsque le boîtier intérieur se déplace entre les première et seconde positions, ouvrant ainsi un trajet de fluide entre le passage de fluide et la première extrémité.
