るブレーキの比例減圧弁。 a valve body having an input chamber and an output chamber; a plunger disposed within the valve body and provided with a small diameter portion facing the input chamber; a medium diameter portion; and a large diameter portion facing the output chamber; The input and output chambers are in communication with each other in a low pressure region of the input hydraulic pressure, and the large diameter portion of the plunger and the first cutoff valve are arranged in a medium pressure region. The input and output chambers are intermittently shut off due to intermittent contact, and in the high pressure region, the input and output chambers are intermittently shut off due to intermittent contact between the middle diameter portion of the plunger and the second shutoff valve. A proportional pressure reducing valve for a brake, characterized in that the plunger is configured to be moved according to the magnitude of input oil pressure.
