ABSTRACT:
In the assembly of a master cylinder and an oil-hydraulic booster connected to the rear thereof, the master cylinder has an axial bore consisting of a forward, small-diameter bore section and a rearward, large-diameter bore section and the master cylinder piston in the master cylinder includes a small-diameter section slidably fitted in the small-diameter bore section of the master cylinder and a large-diameter section slidably fitted in the large-diameter bore section thereof. The forward end portion of the piston in the oil-hydraulic booster is formed smaller in diameter than the large-diameter bore section of the master cylinder and is arranged proximate the large-diameter section of the master cylinder piston in the master cylinder so as to enter the large-diameter bore section of the master cylinder when the booster piston is advanced. Provided for the booster piston slidably fitted in the oil-hydraulic booster cylinder is a first stop means arranged to define the limit of retraction of the booster input rod in such a manner that, in the process of retraction of the latter, the opening of an output valve arranged to control communication between the output hydraulic pressure chamber of the booster and the oil reservoir tank reaches its maximum as the booster piston reaches its limit of retraction. A second stop means is provided on the booster cylinder to define the retraction limit of the input rod so that the opening of the output valve is minimized with the booster piston reaching its limit of retraction.
