How the VR300 Fast Fuel System Works |
|
|
|
|
 |
 |
 |
1.
The nozzle and receiver mate using bayonet lugs. A 30° turn locks and
seals the two mating components. The nozzle actuating handle will not
move unless the nozzle has been attached and locked onto the receiver. |
|
2.
The nozzle actuating handle is rotated upward to the "ON" position
which opens the nozzle and receiver poppets. Fuel flows through the
nozzle and builds pressures within the receiver. Pressurized fuel
flowing through the jet sensor opens the main fuel gate.
|
 |
|
 |
3. Fuel fills tank at a rate up to 300 GPM. |
|
4.
When the fuel level reaches jet sensor, the pressure maintaining the
open position of the main fuel gate is eliminated. A return spring
closes the main gate and fuel ceases to flow into the tank.
|
 |
|
 |
5.
With the main fuel gate closed the pressure within the receiver and
nozzle builds. Pressurized fuel is forced through the hollow nozzle
actuator shaft into the poppet return chamber. The pressure in the
poppet return chamber pulls the nozzle sealing poppet back to the
closed position, and the red indicator button extends out the back of
the nozzle.
|
|
6.
The extended indicator button signals that the nozzle actuating handle
may be rotated to the "OFF" position. Only when the actuator is in the
"OFF" position will the nozzle rotate off the receiver. |
