ことを特徴とするブレーキの比例減圧弁。 A valve body provided with an input chamber having an input port and an output chamber having an output port, and a plunger disposed within the valve body and provided with a small diameter portion facing the input chamber and a large diameter portion facing the output chamber. , includes a sleeve facing the output chamber and equipped with a blockage valve that closes the output port, and a shutoff valve placed between the input and output chambers. In the pressure region, the input and output chambers are intermittently shut off due to intermittent contact between the large diameter portion of the plunger and the shutoff valve, and in the high pressure region, the output port is blocked by the blocking portion of the sleeve. A proportional pressure reducing valve for a brake, characterized in that the plunger and sleeve are configured to be moved in accordance with the magnitude of input hydraulic pressure.
