ABSTRACT:
An anti-cavitation plate actuating system incorporates pressurized air selectively applied through a control valve to an air assist cylinder. The cylinder, when pressurized, applies force to anti-cavitation plate return springs; the force is not sufficient to expand or retract the springs but merely to apply a pre-load. A control pedal operating through a control shaft applies additional force through an actuating shaft connected through a control lever to the anti-cavitation plate to lower the plate.
