Abstract

A master cylinder has a housing with a (stepped) bore (28) therein having a tapered section (34) located between first and second compensator ports (40, 42) connecting the bore (28) to a reservoir (44, 46). A stepped sleeve (74) locates first and second lip seals (114, 115) adjacent the first and second compensator ports (40, 42) respectively. A first piston (52) engages the first lip seal (114) and a second piston (54) engages the second lip seal (115) to define first (56) and second (72) chambers within the bore (28). A bearing member (110) which surrounds the first piston (52) engages the sleeve (74) and holds the first (114) and second (115) lip seals in a stationary position within the bore (28). Thereafter, an input member (24) moves the first (52) and second (54) pistons past the first (114) and second (115) lip seals to pressurize the fluid in the first (56) and second (72) chambers and provides fluid pressure responsive devices (14, 16) with an operational input through first and second outlet ports in the housing. <IMAGE>
