Abstract

PURPOSE:To improve twice treading effects of the brake in such a way that a valve device assembly which is installed on the path between a reservoir and a supply chamber is pressed at the determined position by means of a resilient material, and the valve device assembly is not allowed to be moved by fluctuation of liquid pressure. CONSTITUTION:A liquid outlet port 26 of a reservoir tank 2 is inserted to a working liquid inlet port 28 which is formed on the cylinder body 1, and communicated to a supply chamber 10. A valve device assembly 31 is installed in the inlet port 28, and it is held in place by means of a snap ring 42 not to be slipped out. And, a Belleville spring 44 is provided on the lower side of the valve device assembly 31, and it presses the valve device assembly 31 to the position to the brought into contact with the snap ring 42. When the supply chamber 10 comes to be in the negative pressure condition, set load of the Belleville screw 44 is set larger than the liquid pressure to be applied from the side of the reservoir tank 2 to the valve device assembly 31.
