ABSTRACT:
In a female coupling component (1, 2) which forms part of a quick coupling there is present a unit (12) so arranged as to be capable of longitudinal displacement in the longitudinal sense of the female coupling component. The unit supports at its first end a first sealing component (14) which is capable of interacting with a seat (1b) in the female coupling component. At its second end the unit supports a second sealing component (15) which is capable of interacting with a sleeve (7) so arranged as to be capable of longitudinal displacement in the female coupling component. The unit comprises an elongated hub component and extending from it wing-shaped elements (25) by means of which the unit which is capable of longitudinal displacement is centered in the female coupling component and between which the fluid passageways lead into the female coupling component.
