Figure 1-1.1 Location and Description of Major Components (D-1R)
a.
Nozzle Body.
The nozzle body (1) contains the poppet assembly and fuel strainer.
b. Nozzle Collar.
The nozzle collar (2) mates with aircraft receptacle. The bumper on face of collar and the internal
slots allow positioning of the nozzle before poppet valve can be opened,
c.
Handle Assembly.
The handle assembly (3) allows the poppet assembly to he opened and closed.
d.
Swivel Elbow. The swivel elbow (4) rotates with the nozzle engaged allowing the hose to be positioned free of
kinks or twists.
e.
Cover. A cover (5) is furnished to cover the nozzle outlet when not connected to a system for servicing.
f.
Ground cable. A ground cable (6) is provided for grounding and bonding the nozzle to the aircraft prior to
connection.
g.
Coupling Assembly. The coupling assembly (7) allows the nozzle assembly to be connected to and disconnected
from a fuel service source.
h. Hose End Regulator. The hose end regulator (8) provides relatively constant pressure of 45 psi. It responds to
increases in pressure within the aircraft fuel manifold caused by closure of the aircraft's fuel tank level control
valves to either maintain desired pressure or to close to prevent an excessive "surge" pressure from being sensed within
the aircraft.
