MAJOR COMPONENTS
PRINCIPLES
OF
OPERATION (Continued)
e.
Internal Valve Assembly (1).
The internal
valve assembly contains a spring loaded piston
(2) which closes the internal valve when in
contact with the seat. When the pilot valve
assembly is pressurized, it opens the piston
allowing fuel to enter the tank through the
internal valve assembly.
f.
Level Control Switch (3). When the converter
assembly is used in a commercial operation, an
electrical connection to the electrical receptacle
(4) shall be made. This allows the level control
switch to interrupt electrical power when the tank
is full.
g.
Latch Cover Levers (5). The
levers are used to
engage/disengage and lock/unlock the latches
(6). When the lever is rotated clockwise (toward
the center of the converter assembly) the latch is
unlocked, allowing the converter assembly to be
installed into or removed from the tank. When
the lever is rotated counter clockwise it engages
the latch and when the lever is lifted toward the
outside of the converter assembly it locks the
latch in the tank.
h.
Latches (6). With the latches in the engaged/
locked position (lever (5) toward outside of
converter assembly) the converter assembly is
locked into the tank. If the tank internal pressure
exceeds 3.5 psig, the spring (7) will allow the
converter assembly to lift off of the tank
opening, relieving the pressure.
