Title: Brake boosting master cylinder
Inventor: OKA HIROYUKI
IPC: B60T13/12
Filed: 2000-11-09
Abstract: PROBLEM TO BE SOLVED: To variously change an input side stroke characteristic without being influenced by the output side, and to boost master cylinder pressure at boosting required time with a simple structure. SOLUTION: When an input shaft 53 advances at actuating time, a control valve 54 is actuated to generate fluid pressure according according to input in a reaction chamber 38 and a pressurizing chamber 35. Since a stepped spool 45 for constituting a part of the control valve 54 strokes so as to balance the action force by this fluid pressure and spring force of a spring 51, the stepped spool 45 functions as a stroke simulator. The stroke characteristic of the input shaft 53 being the input side can be variously and optionally changed independently of the output side without having influence on MCY pressure being the output side of brake boosting pressure MCY1 by variously setting the respective pressure receiving areas of the stepped spool 45 and the spring force of the spring 51.
