Claims

[Scope of utility model registration request]

An assembly of a mask cylinder and a pressure reducing valve capable of reducing the pressure and transmitting the output hydraulic pressure of the mask cylinder to the 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. In addition, a valve surface whose outlet communicates with the rear wheel brake, and a valve surface that slides into 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 communicating with both hydraulic chambers; a valve body disposed within the input hydraulic chamber and opening and closing 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 in a direction away from the valve body, wherein the valve face has the inlet. It is composed of a first half that is integral with the mask cylinder, and a second half that has the outlet and is screwed onto the first half, and the first half has the valve body, the valve spring, and A regulating member is provided for regulating the amount of movement of the valve body due to the expansion of the valve spring, and the second half is provided with the pressure receiving piston and the pressure regulating spring, and is in contact with the valve body, so that the pressure receiving piston and the pressure receiving piston are in contact with the valve body. A master cylinder/pressure reducing valve assembly characterized by forming a contact surface that determines a gap between pistons.
