Title: Brake booster
Inventor: TAKAHASHI MITSUGI
IPC: B60T13/57
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To enhance a brake feeling in a normal operating range by making its responsiveness dull at the early stage of braking in a negative pressure type brake booster, and try to shorten its brake stopping distance by improving the responsiveness at the time of panic braking causing a brake pedal to be greatly stpped in. SOLUTION: In this negative pressure type brake booster, a throttling mechanism 10 is formed out of a variable position piston 11 fixed to an operating rod 1, and of a circumferential wall part 13 enclosing the piston while the gap 14 is being kept around its circumference, and the gap 14 is turned out to be an ambient pressure inflow passage to a variable pressure chamber, and the gap 14 is so constituted as to be changed in size because of the change in position of the variable position piston 11 with respect to its circumferential wall part 13 when the operating rod 1 is moved in the axial direction. By this constitution, the flow rate per hour of ambient pressure to the variable pressure chamber is so controlled as to be changed in such a way that it is small at the early stage of pedal stepping, but is increased as a stepping stroke becomes greater.
