Abstract

PURPOSE: To ensure the required braking pressure characteristics following changes in the loaded weight by varying the required reactive deceleration of the ball valve corresponding to the changes.
CONSTITUTION: A plunger 11 moves to change the static position of a ball valve 10 when the working oil pressure in a first working oil chamber 1 exceeds a given level. In this apparatus mounted slightly inclined to the level, the ball valve 10 stands still at the stable position supported by the rolling surface and the plunger 11 when the brake is out of action. An inclined stepped section 14 is so arranged that when the plunger 11 begins to move above the given pressure level, the ball valve 10 is sunk from a general surface to slant surfaces 15a and 15b so as to change the reactive deceleration of the ball valve 10. The steps t and t and the inclination angle of the step section 14 are set so that the reactive deceleration can be obtained according to the weight of load, heavy or medium, thereby ensuring ideal braking force.
