Abstract
A brake fluid pressure generating device includes a first valve element connected to an input shaft, a first force device connected to the first valve element to provide a counter force relative to a force applied to the first valve, a second valve element situated adjacent to the first valve element, a power cylinder unit actuated by the first valve, a second force device situated between a power cylinder unit and the second valve element to move the second valve element, and a third force device connected to the second valve element to provide a counter force relative to a force applied to the second valve. A master cylinder is connected to the power piston to generate a master cylinder pressure to thereby output a regulated control valve output pressure. A desired stroke characteristic of the brake can be obtained.
