Abstract: Provided herein are couplings useful in the transfer of liquid fuels from a remote storage reservoir to an on-board fuel tank of a motorized vehicle. There is provided a first coupling which is adapted to be in fluid communication with the interior of a vehicle's fuel tank, and a second coupling which is intended to be in fluid communication with the contents of a remote fuel storage reservoir. The invention also includes a process for charging a fuel reservoir on board of a motorized vehicle from a remote reservoir, wherein the vapor in the fuel reservoir is displaced by an equal volume of fuel delivered from said remote reservoir, and wherein the vapor in said fuel reservoir is simultaneously caused to be transferred to said remote reservoir, thus permitting no escape of the vapor from said fuel reservoir to the surrounding atmosphere.

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.
