ABSTRACT:
A differential hydraulic master cylinder (10) has a cylinder body (12) in which is provided a larger diameter first chamber (18) and a smaller diameter second chamber (20). A first fluid passageway (60, 74, 78, 80) connects the first chamber (18) with a source of ambient pressure and contains a pressure relief valve (70) for connecting the first chamber with said source of ambient pressure when the pressure in the first chamber reaches a threshold value. A second fluid passageway (76, 78, 80, 82) connects the first chamber (18) with an outlet (11) and the second chamber (20). A non-return valve (72) is located in the second passageway to prevent hydraulic fluid from flowing from the second chamber (20) to the first chamber (18) at least when the pressure relief valve (70) is open. The non-return valve (72) and the pressure relief valve (70) each have a movable valve member (100, 102, 88; 122) which are mechanically interconnected.
