Claims

[Scope of utility model registration request]

A small cylinder hole 29 and a large cylinder hole 3 are sequentially drilled and arranged in the housing 1, and a slide sleeve 6 is slidably and fluid-tightly fitted between the small cylinder hole 2 and the large cylinder hole 3. At the same time, the open end of the large cylinder hole 3 is closed with a joint bolt 5, and the large diameter portions 1 and 0 of the piston 9, which consists of a large diameter portion 10 and a small diameter portion 12, are connected to the small cylinder hole 2.
At the same time, the small diameter portion 12 is slidably and liquid-tightly fitted into the slide sleeve center hole 13 and the non-penetrating center hole 16 of the upper joint bolt, and the small diameter portion 12 is slidably and liquid-tightly fitted into the small cylinder hole of the piston 9. A ball valve chamber 18 is recessed in the end of the second side, and when the piston 9 moves to the small cylinder hole 2 side, the ball valve 20 disposed in the ball valve chamber 18 is recessed at the bottom of the small cylinder hole 2. (opened by the joint pin 23 fixed upright)
The bottom of the small cylinder hole 2 is connected to the outlet hole 29 leading to the wheel cylinder of the rear wheel, and the flange 24 and the slide sleeve 6 are connected to each other between the large diameter part 10 and the small diameter part 12 of the piston 9. Compression coil spring 25 between
The inlet hole 26 communicating with the master cylinder is communicated with a central chamber 27 in which a spring 25 is arranged, and the central chamber 27 is communicated with the ball valve chamber 18 via an oil hole 28 provided in the piston 9. The load-responsive pressure reducing valve is characterized in that it is formed between the slide sleeve 6 and the joint bolt 5 through a passage 1330.31 and communicates with the control chamber 32.
