Brake fluid pressure control device for vehicle

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.
