Abstract
A fluid power system (10) for a lift truck (18) has a movable steering device (12) and a valve (14) which moves in response to movement of the steering device (12) a preselected amount to supply fluid power for steering the lift truck (18). Apparatus (30) is provided for controllably supplying fluid power to the valve (14) prior to the valve (14) moving to supply fluid power for steering. The apparatus (30) eliminates delay between the moving of the valve (14) and the availability of fluid power at the valve (14) to insure quick, responsive steering.
