COMPONENT OPERATION / Pilot Valve SHOCKLESS FUNCTION (ONLY FOR TRAVEL PILOT VALVE) The travel pilot valve has the damper enabling damp- ing of the speed change shock by the travel lever. The damper is composed of support, gears 1 and 2 and others. Gear 1 is connected with the support. The support is secure to the bracket by using a spring pin. The travel lever and travel pedal are secure to the bracket. Therefore, the support swings transversely around the pin in line with the movement of the travel lever. Operation 1. If the travel lever is released from the hand during traveling, spring force of the return spring returns the travel lever to the neutral position. 2.
At this time, gears 1 and 2 inside the damper re- ceive opposing force due to friction. 3. Therefore, as the travel lever gradually returns to the neutral position, the extent of sudden stop at the time of abrupt release of the travel lever is damped down.
