ンチロツク装置用モジユレータ。 A master cylinder 1 is divided into a first chamber 3 and a second chamber 4 into which a piston 2 is slidably fitted, and a first relief valve 5 is inserted into the piston 2 to form a second chamber from the first chamber 3. The master cylinder 1 is provided with an auxiliary piston 6 that slides in a direction perpendicular to the piston 2 in a liquid-tight manner while regulating the hydraulic pressure reaching 4. The auxiliary piston 6 has a large diameter portion 7 at the base and a small diameter portion at the tip. The auxiliary piston 6 is connected to an auxiliary hydraulic pressure source 8 for the anti-lock device, and the large diameter portion 7 is provided so as to be able to protrude into the second chamber 4 according to the pressure, and the piston 2 is connected to the first chamber 4. 3rd to 2nd
A second relief valve 9 is provided to regulate the hydraulic pressure reaching the chamber 4, and this second relief valve 9 is positioned facing the large diameter portion 7. The second relief valve 9 is pressed by the projection of the large diameter portion 7 into the second chamber 4 due to the pressurizing operation of the pressure source 8, and the second relief valve 9 is moved from the first chamber 3 to the second chamber 4 before the first relief valve. 1. A modulator for an anti-lock device, characterized in that the liquid path leading to the lock is configured to be in an open state.
