Abstract

PURPOSE: To perfectly divide operation oil by arranging a flexible diaphragm which forms a low pressure chamber between a piston, on one side of the power piston, and constituting a booster so that the power piston operates the piston of a master cylinder through said diaphragm.
CONSTITUTION: When a power brake is operated and an input shaft 3 is moved rightward and a communication hole 32 is closed, liquid pressure is applied to a power piston 15, and the power piston 15 is moved rightward by the liquid pressure and the force which pushes the input shaft 33. Accompanied with the movement of the piston 15, pressurized oil is sent out to the disc-brake side from a discharge port so as to move a piston 19 rightward. At this time, a flexible diaphragm 26 is deformed, accompanied with the movement of the rods 25 and 26 in a space 27. Accordingly, as the rods 16 and 25 are contacted, having the flexible diaphragm 26 interposed, sliding surface does not exist between these three 16, 25, and 26, so the leak of the operating oil from the sliding surface does not occurr, and the liquid tightness between cylinders 13 and 18 is secured.
