<p>A coupling device (10) includes a nozzle (11) and a receptacle (12). The receptacle (12) includes a poppet assembly (35) that is biased by a spring (41) to a closed position. The receptacle (12) also includes an interface sealing surface (31). The nozzle (11) includes a nozzle valve (75) having a poppet (76) and a valve seat (79). The nozzle (11) also includes an interface seal assembly (85) movable between opened and closed positions relative to the receptacle interface sealing surface (31). The valve seat (79) and the interface seal assembly (85) are both carried on a movable carrier (88), and an actuator assembly (95) is operably connected to effect movement of the poppet (76), the valve seat (79) and the interface seal assembly (85). The actuator assembly (95) holds the interface seal assembly (85) opened during coupling and uncoupling of the nozzle (11) and receptacle (12) and closed during opening and closing of the nozzle valve (75) and receptacle poppet assembly (35). A collar (48) locks the receptacle (12) to the nozzle (11). Frangible fasteners (52) break to permit separation of the receptacle (12) from the nozzle (11) under defined conditions, and the carrier (88) moves the valve seat (79) to engage the poppet (76) and close the nozzle valve (75) under such conditions.</p> |
