Abstract
PURPOSE: To facilitate air suction in the brake system by opening the first fill valve when a cap at liquid infusing port of a reservoir is opened.
CONSTITUTION: The first fill master cylinder 1 equipped with a stepped piston 3, a large diametral port 1a, and a small diametral port 1b provides the first fill valve 35 composed of a check valve 40 in a reservoir 2. The first fill valve 35 provides a differential pressure valve composed of a valve seat 36 and a valve body 37, and the differential pressure valve works in response to the forces of the first spring 38 and the second spring 41. A spring seat 39 to press the first spring 38 is pressed by a filter 33, and the filter 33 is pressed by a cap 32 at the liquid infusing port. When the cap 32 at the liquid infusing port is closed, since the differential pressure valve is closed, the first fill function is not hindered at all, when it is opened, the master cylinder is conducted to the reservoir, so that air in the brake system can be sucked.
