Abstract
A master cylinder (10) for a hydraulic brake system comprises a quickfill stage (28) which in the initial phase of an actuation of the master cylinder rapidly fills an associated brake system with hydraulic fluid upon a relatively short actuation travel. A housing (12) of the master cylinder (10) extends essentially along an axis (A) and comprises at least one pressure chamber (14) formed therein which is open at the actuation end of the master cylinder (10). A quickfill piston and a quickfill chamber of the quickfill stage (28) are essentially formed by a cup shaped component (30) which is guided on the acutation end of the master cylinder housing (12) in a telescopical and pressure chamber sealing manner. This solution can be manufactured economically and requires little installation space.
