Claims

[Scope of utility model registration request]

An assembly of a mask cylinder and a pressure reducing valve capable of reducing and transmitting the output hydraulic pressure of the mask cylinder to a rear wheel brake, the pressure reducing valve being provided in the mask cylinder and having an inlet connected to an output port of the mask cylinder. and a valve surface whose outlet is connected to the rear wheel brake, respectively, and a valve surface that is slidably fitted within the valve surface so as to partition the inside thereof into an input hydraulic chamber connected to the inlet and an output hydraulic chamber connected to the outlet. a pressure-receiving piston having a communication hole that communicates the pressure chambers on both sides; a valve body that is disposed within the input hydraulic pressure chamber and opens and closes the communication hole during pressure reduction;
A valve spring that biases the valve body toward the pressure receiving piston, and a pressure regulating spring that biases the pressure receiving piston and the piston in a direction away from the valve body, wherein the valve surface is connected to the inlet. a first half integral with the mask cylinder;
a second half that has the outlet and is screwed onto the first half; the valve body and the valve are fitted into a valve cylinder that is fitted into an opening on the first half of the second half; Incorporating a spring to create a valve body
A mask cylinder/pressure reducing valve assembly comprising a valve spring unit, wherein the pressure receiving piston and the thickness adjusting spring are assembled in the second half to form a pressure receiving piston/pressure adjusting spring unit.
