ABSTRACT:
A device for opening a door on an aircraft to expose a receptacle for receiving a fueling nozzle on another aircraft so that the first mentioned aircraft can be refueled in flight. The device has a hydraulically operated actuator for opening and closing the door and another hydraulically operated actuator for locking and unlocking latches engageable with the nozzle for holding it in the receptacle. The hydraulic system has a single valve for controlling flow of pressurized fluid through a single conduit to the door actuator for both door opening and door closing movement of the actuator piston. When closed, this valve isolates the hydraulic system from the pressure source so that no part of the hydraulic system is pressurized when the device is not in operation.
