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.
