Abstract
PURPOSE: To simplify an operation system by using a single selector valve which has speed change combination patterns.
CONSTITUTION: Brake cylinder circuits of frictional brake cylinders H, L, R,I, II, III of gear trains include first to fifth pilot differential shift valves 10W14, respectively. Shifting motions of the pilot differential shift valves are controlled by a single selector valve 29 which selectively releases pilot pressure drain circuits 24W28. The single selector valve 29, having combination change-over positions of speed change patterns, combines the pilot differential shift valves 10W14 of the frictional brake cylinders for shifting to supply pressurized working fluid, for engaging the brake.
