A female coupling for a fluid quick connector and configured to be removably connected to a male coupling of the connector. The female coupling includes a valve assembly with a valve alternating between closed and open positions. The flow of a fluid from the female coupling towards the male coupling occurs in the open position. The female coupling includes a hollow body defining an inner cavity with a longitudinal axis for the flow of the fluid. The female valve assembly is housed in the inner cavity. The hollow body includes an end portion configured to be housed in a housing seat of an interface manifold. With the end portion in the housing seat, the tubular inner cavity is placed in fluid connection with at least one inner channel of the interface manifold. A constraint prevents rotation/translation of the end portion of the hollow body with respect to the housing seat.

To provide an emergency detachment mechanism for a fluid handling device that has exceptional heat insulation performance and enables liquid hydrogen or another very-low-temperature fluid to be handled. An emergency detachment mechanism for a fluid handling device provided with a pair of couplers 1, wherein each of the pair of couplers 1 has a coupler body part 5 including an internal tube part 2 in which a fluid passes through an interior and which opens at a distal end side, an external tube part 3 which forms a vacuum layer 9 with the internal tube part 2 and which opens at a distal end side, and a connecting flange part 4 that closes off a space between the internal tube part 2 and the external tube part 3, a wall thickness of the connecting flange part 4 being less than a wall thickness of the external tube part 3.

A fluid coupling includes a male element and a female element, which has a gear reduction member and a main body defining a main inner channel, a plunger, and a slide valve movable between a closed configuration and an open configuration. The slide valve has an outer slide valve and an inner slide valve. In the closed configuration, the outer slide valve is in a forward position and the inner slide valve is in a forward position contacting the outer slide valve and the plunger. In the open configuration, the outer slide valve is in a withdrawn position and the inner slide valve is in an offset position. The gear reduction member is disengaged from a front stop surface on the main body, a rear stop surface on the outer slide valve, or a front stop surface on the inner slide valve during a coupling phase.

The invention relates to a locking coupling including a first coupling unit and a second coupling unit, which in each case extend along a longitudinal axis and are designed to be identical. Each coupling unit includes a valve unit and a locking unit. The first and the second valve unit are designed to form a fluid connection between the first and the second coupling unit, and the first and the second locking unit are designed to connect the first coupling unit and the second coupling unit mechanically to one another. The first coupling unit includes an actuating element, by actuation of which the first and the second coupling unit can be mechanically connected to one another via the first and the second locking unit and can be fluidically connected to one another via the first and the second valve unit.
