Fluid coupling assemblies and methods are discussed. The fluid coupling assemblies include a first coupling member, a second coupling member magnetically engageable with the first coupling member, and a seal member disposed between a portion of the first coupling member and a portion of the second coupling member. A magnetic engagement of the first coupling member and the second coupling member unseals a fluid flow path therebetween. In certain examples, the first coupling member is sealed by a valve member and the second coupling member includes an activation member. When engaged, the valve member is moved from a closed position to an open position by the activation member, thereby unsealing the fluid flow path. A magnetic force between the first coupling member and the second coupling member can be chosen such that the members disengage when a predetermined fluid flow path pressure is reached.

L'invention concerne des ensembles et des procédés de couplage de fluide. Les ensembles de couplage de fluide comprennent un premier élément de couplage, un second élément de couplage pouvant s'engager de façon magnétique avec le premier élément de couplage, et un élément d'étanchéité disposé entre une partie du premier élément de couplage et une partie du second élément de couplage. Un engagement magnétique du premier élément de couplage et du second élément de couplage descelle un trajet d'écoulement de fluide entre ceux-ci. Dans certains exemples, le premier élément de couplage est scellé par un élément de soupape et le second élément de couplage comprend un élément d'activation. Lorsqu'il est engagé, l'élément de soupape est déplacé d'une position fermée à une position ouverte par l'élément d'activation, descellant ainsi le trajet d'écoulement de fluide. Une force magnétique entre le premier élément de couplage et le second élément de couplage peut être choisie de telle sorte que les éléments se désengagent lorsqu'une pression de trajet d'écoulement de fluide prédéterminée est atteinte.
