BRAKE PRESSURE INTENSIFIER FOR SECURING SAFE SEPARATION DISTANCE FOR SUDDEN BRAKING BY GENERATING NEGATIVE PRESSURE FROM A VENTURI TUBE AND REGULATING NEGATIVE PRESSURE OF A BRAKE BOOSTER WITH THE NEGATIVE PRESSURE

摘要

PURPOSE: A brake pressure intensifier is provided to improve braking power of a brake by adjusting negative pressure of a brake booster with a solenoid valve and to apply for general vehicles without an ABS(Anti-Lock Brake System). CONSTITUTION: A brake pressure intensifier is composed of a venturi tube(20) disposed at a predetermined region of an air duct(10) mounted to inject the air to an engine and to generate negative pressure; a connection pipe(30) of which one end is connected to the venturi tube to keep negative pressure; a check valve(40) disposed at the other end of the connection pipe; a solenoid valve(50) for regulating negative pressure of a booster(90) with the negative pressure supplied from the check valve; a potential sensor(70) for measuring efforts of a brake pedal(60); and a control unit(80) for comparing the effort measured by the potential sensor with reference effort of the vehicle and then controlling the check valve and the solenoid valve.
