DESCRIPTION AND OPERATION
1. Description
The Underwing Refueling Nozzle (nozzle) (See Figure 1) provides the means of controlling the flow of
fuel in pressure fueling operations. The nozzle inlet port couples to a fueling hose. The outlet port
attaches to the inlet adapter of the system being fueled. The nozzle provides a leak-proof connection
between the system being fueled and the fuel supply.
2. Operation
A. Uncoupled
When the nozzle is not coupled to a mating fuel system inlet adapter, its poppet valve is closed, so
that there is no flow or leakage of fuel from the outlet port. The flow control handle that operates
the poppet valve remains locked in the CLOSED position until the nozzle is coupled to the mating
fuel system inlet adapter.
B. Coupling and Opening
When the nozzle is coupled to the mating fuel system inlet adapter, the nose seal of the nozzle is
compressed against the sealing surface of the inlet adapter to form a fluid-tight connection. When
the nozzle is fully engaged and locked to the bayonet flange of the inlet adapter, the flow control
handle is unlocked. Rotation of the flow control handle to the OPEN position opens the poppet
valve, providing a flow passage into the system being fueled. As the system is being fueled, fuel
pressure acts on the floating nose seal of the nozzle to increase the sealing force.
C. Closing and Uncoupling
Rotation of the flow control handle to the CLOSED position closes the poppet valve and the flow
passage into the system being fueled. When the nozzle is unlocked and disengaged from the
bayonet flange of the inlet adapter, the flow control handle is locked in the CLOSED position.
D. Adapters
Suitable attachment adapters such as swivels and/or hose end control valves (HECV) may be
used to adapt the nozzle to any fuel system.
