Q
When Clutch Pedal is Depressed (with Shuttle Lever at Reverse or Forward Position)
W1015685
With the shuttle lever at R or F position, when the clutch pedal is depressed, the inching valve (4) is moved to the
right. And connect the passage 1 (f) to T2 port. As the proportionally reducing valve (1) is moved to the right by
pressure difference, R port (or F port) and T2 port are connected.
The oil in the shuttle clutch returns into the transmission case via R port (of F port) through the proportionally
reducing valve (1) and T2 port. This cause the shuttle clutch to be set to off.
As a result, even when the proportionally reducing valve (1) does not move, the oil passage from R port (or F side)
to T2 port is secured.
