Exhaust Air
When the Trigger is depressed (1), the
Throttle Valve moves to the down position
(2), and pressurized air is directed to the
bottom of the Air Piston, causing it to move
upward (3). The air above the Piston is
exhausted and directed through the center
of the Throttle Valve and out the bottom
of the tool (4). The Air Piston has a Rod
and a Hydraulic Piston attached. When the
Air Piston rod moves upward, a column of
pressurized hydraulic fluid is forced up (5)
into the tool head, which moves the Pull
Piston back (6). The attached nose assembly
moves with the Pull Piston to start fastener
installation. When fastener installation is
completed, the Trigger is released (7). Air
pressure, with the assistance of a Spring (8),
causes the Throttle Valve to return to its up
position (9). Pressurized air is re-directed to
the top of the Air Piston, causing it, along
with the Hydraulic Piston Rod, to move
downward (10). The air from below the Air
Piston is exhausted through the bottom
of the tool (11). As this occurs, hydraulic
pressure is reversed and the Pull Piston is
returned forward (12). A return pressure
relief valve protects the tool against pressure
spikes. The reservoir replenishes the hydraulic
system as needed.
