Abstract: An aircraft fueling nozzle has a body with a bearing sleeve mounted within the body. The nozzle has a poppet having a stem which is guided by the bearing sleeve. A seat is mounted in the nozzle body for forming a seal with the poppet head. The seat is retained in the body by a resilient lip which encompasses the seat projecting outward and interacts with an inwardly projecting lip on the body. The nozzle has a linkage for moving the poppet including an actuator located upstream of the bearing sleeve which is connected to an arm which overarches the bearing sleeve and is connected to the poppet. The actuator includes a crank which is connected to the arm and an actuator shaft which connects to the crank by interfitting splines. The nozzle further includes a swivel for rotatably coupling the nozzle body to a fuel supply. The swivel includes a replaceable annular bearing ring. The nozzle includes recesses for receiving the lugs of an aircraft fueling flange to secure the flange to the nozzle.

Abstract: A ball valve has a housing which rotatably carries a ball. The housing has inlet and outlet ports. The ball has two ports which may be rotated to align with the housing's ports. The ball carries a cartridge in a cartridge compartment located transverse to the ball ports. The cartridge has inlet and outlet ports between which a cartridge flow passage is defined. A strainer is located within the cartridge flow passage. The ball and cartridge may be rotated to an orientation in which the ball ports are substantially transverse to the housing ports, from which orientation the cartridge may be extracted from the ball and housing and the strainer may be removed from the cartridge.

Abstract: An aerial refueling system includes a reel mounted for rotation about a central axis for winding and unwinding a hose. A sheave is provided to receive the hose as it leaves the reel and to change the direction of the hose so that it trails axially of the reel. The sheave is mounted on a non-rotating carriage which is supported by the reel and moves axially along the reel as the reel rotates.
