Figure 1-7. Mini-Valve Left Port Activated
• Spool Valve -Pushed to the right by electric
solenoid. This opens the internal oil pressure
galley allowing the fluid to go through the check
valve and on to the cylinder. Also, the spool valve
opens the oil return line providing an oil path
through the internal oil galley back to the reservoir.
• Pilot Plunger Valve - Right pilot plunger valve
is pushed up by the incoming oil pressure mechani-
cally opening the check valve located above it in the
return circuit. This action allows the oil from the
return side of the slave cylinder to go back into the
reservoir. The left pilot plunger valve is not
affected in this operation mode.
• Check Valves - Both check valves are opened
in this operation mode. The left check valve is
pushed open by the oil pressure created by the
pump. The oil then continues through the lines and
supplies the inlet pressure to move the slave
cylinder piston. The right check valve is held open
mechanically by the pilot plunger and allows the oil
from the return side of the slave cylinder to go
through the mini-valve back to the reservoir.
• Speed Control - The left speed control
(output side) does not have any effect in this
operation mode because the oil is routed around
the speed control through a bypass valve to the
output port. The right speed control controls the
speed of the table function by restricting the flow of
oil going back into the reservoir.
