Abstract:
Connector system for coupling a pressurized-fluid line that accommodates a flow of pressurized fluid to a receiving line for receiving said fluid, comprising an upstream tubular body (1) capable of being connected to the pressurized-fluid line, a downstream tubular body (2) that can be plugged into the upstream tubular body and is capable of being connected to the receiving line, and means (29, 60, 71, 78) for locking the downstream tubular body plugged into the upstream tubular body, characterized by a first shutter (18) housed in the upstream tubular body (1) and bearing against a seat (6) thereof under the action of a first elastic stress (20) upstream of the first shutter, a second shutter (49) housed in the downstream tubular body (2) and bearing against a seat (38) thereof under the action of a second elastic stress, and first bearing means (24, 25) secured to the first shutter (18) interacting with second bearing means (55) secured to the second shutter (49) and third bearing means (57) secured to the downstream tubular body (2), so that when the tubular bodies (1, 2) are connected respectively to the pressurized-fluid line and to the receiving line, and when the downstream tubular body (2) is plugged into the upstream tubular body (1), the second shutter (49) then the first shutter (18) are moved in turn of their respective seats, the second shutter (49) being moved against the action off the second elastic stress (51) and the first shutter (18) being moved against the action of the first elastic stress (20) and of the pressurized fluid, and so that as the downstream tubular body (2) is withdrawn from the upstream tubular body (1), the first shutter (18) then the second shutter (49) are allowed to return in turn against their respective seats, the first shutter (18) under the combined action of the first elastic stress (20) and of the pressurized fluid, and the second shutter (49) under the action of the second elastic stress (51).
