Title:
MASTER CYLINDER UNIT
Document Type and Number:
WIPO Patent Application WO/2017/022545
Kind Code:
A1
Abstract:
The present invention is provided with: a simulator pressure chamber which communicates with a pressure chamber of a master cylinder, and which causes a simulator piston to move as a result of introduced hydraulic pressure; an impelling chamber having, disposed therein, an impelling mechanism for impelling the simulator piston against the hydraulic pressure introduced into the simulator pressure chamber; a simulator replenishment chamber which communicates with a master replenishment chamber; a first seal member which demarcates the simulator replenishment chamber and the simulator pressure chamber; and a second seal member which demarcates the simulator replenishment chamber and the impelling chamber, and which allows the flow of a brake fluid from the simulator replenishment chamber to the impelling chamber when a pressure difference is generated between the simulator replenishment chamber and the impelling chamber.
