Title: Hydraulic pressure regulating system

Abstract: A hydraulic pressure regulating system for a vehicle having a regulator valve, a shift valve and a plurality of fluid actuated clutch means, wherein an accumulator being provided between the regulator valve and the shift valve is so designed as to control the fluid pressure to keep it relatively low when the fluid actuated clutch means is in its initial engagement condition and communicates with the regulator valve so as to increase the fluid pressure sufficiently to provide for the full engagement of the fluid actuated clutch means when the clutch means becomes substantially fully engaged.
