8-2. Operation Principle
The operation of the Model NV 45AB2 is illustrated and described in Figures 4 through 7. The [Bold] numbers in
the descriptions correspond to the item numbers shown in the mechanism illustration in Fig. 3. In Figures 5 and
7, read the descriptions in alphabetical order.
(1) When the compressed air source (air hose) is connected to the nailer
Fig. 4
Air pressure is applied to the lower surfaces of the flanges
located at the center portion of the Cylinder [2], forcing the
cylinder upward. The compressed air is thereby blocked
from the upper end of the cylinder, and no pressure is
applied to the Piston [3].
The Accumulator [1] is filled with
compressed air.
The trigger and pushing lever are not
operated, and remain closed.
The exhaust vents are open, and no air
pressure is applied to the valve air passage.
Compressed air is applied to the right-
side surface of the feed piston through
the passage from the accumulator, and
moves the feed piston to the left.
