  • Hydraulic pressure generator
    Patent number: 9522663
    Abstract: A hydraulic-pressure generator including: primary and secondary pistons displaced corresponding to displacement of a brake pedal; a first pressure chamber communicating with a first hollow in the primary piston and generating in brake fluid hydraulic pressure corresponding to the displacement of the primary piston; a second pressure chamber communicating with a second hollow in the secondary piston and generating in the brake fluid hydraulic pressure corresponding to the displacement of the secondary piston; one or more first communication openings formed in a peripheral wall surrounding the first hollow; and second communication openings formed in a peripheral wall surrounding the second hollow. The flow rate of the brake fluid through the one or more first communication openings is different from the flow rate of the brake fluid through the second communication openings.
