<p>VALVE ASSEMBLY A compensation control and blow-off valve unit in a quick take-up master cylinder. In one embodiment, a stamped valve body forms a valve member within a valve chamber which permits compensation flow from the master cylinder reservoir to the pressurizing chambers. It has an O-ring seal controlling a passage from the valve chamber to the reservoir which opens the passage at a predetermined quick take-up pressure to return fluid to the reservoir. Other embodiments use an umbrella valve or a spring biased ball check valve. The valve housing in some embodiments also retains the reservoir housing in sealed position on the master cylinder housing.</p> |
