Abstract
PURPOSE: To obtain specific pressure stably and definitely for a certain time by composing a brake pressure feeder of a cylinder with a depression part at one terminal and a holding part at the other and an air pressure control part connected to the cylinder.
CONSTITUTION: The exhause valve of three-way valve 12 of air pressure control part 15 is opened to decrease the internal pressure of the cylinder, thereby making depression part 8 and holding part 9 in contact with a brake pedal and another fixing member in a car respectively. Next, pressure air is sealed in from intake 16 with the exhaust valve of three way valve 12 closed. Depression part 8 linked to piston rod 3 is applied with pressure and then transmits it to the brake pedal. Because of the installment of nonreturn valve 14, none of air leaks out of cylinder 1, constant pressure can be maintained for a certain time and its pressure value is indicated by pressure gauge 13.
