Abstract:
1. A brake fluid pressure control device for a vehicle comprising: an inlet valve that is configured by a normally opened type electronic valve; an outlet valve that is configured by a normally closed type electronic valve; a reservoir that temporarily stores a brake fluid; a plunger pump that suctions the brake fluid stored in the reservoir; and a base unit having a fluid passage that connects a master cylinder and a wheel cylinder, wherein the base unit comprises: an inlet valve mounting hole in which the inlet valve is mounted; an outlet valve mounting hole in which the outlet valve is mounted; a reservoir hole in which the reservoir is mounted; a cylinder hole into which a plunger of the plunger pump is inserted to freely slide in the cylinder hole; an inflow hole that connects the outlet valve mounting hole and the reservoir hole; a suction hole that connects the reservoir hole and the cylinder hole; and a discharge hole that connects the cylinder hole and the inlet valve mounting hole, wherein the suction hole is configured to be inserted with a suction valve that allows only an inflow of the brake fluid into the cylinder hole, wherein the discharge hole is configured to be inserted with a discharge valve that allows only a discharge of the brake fluid from the cylinder hole, wherein the inflow hole and the suction hole are arranged to be substantially in parallel with each other, wherein the base unit comprises an inlet port that is connected to a pipe extended to the master cylinder, wherein the discharge hole is connected to a master cylinder connection hole that is communicated with the inlet port, and wherein a cross sectional area of the discharge hole is formed to be larger than a cross sectional area of the master cylinder connection hole.
