| 摘要 |
An improved force transfer arrangement for use in a dual circuit master cylinder having a pair of nested concentric pistons for pressurizing a pair of respective fluid chambers, wherein the force transfer arrangement imparts an input force from an input piston on a pair of pistons such that the pair of pistons can move relative to each other to compensate for different travel lengths. The invention discloses three embodiments of the improved force transfer arrangement. A first embodiment includes a hydraulic fluid chamber in fluid communication with the input piston and the pair of pistons. A second embodiment includes a circumferentially arranged ball mechanism positioned between the input piston and the pair of pistons. A third embodiment includes a notched lever ring assembly positioned between the input piston and the pair of pistons. |
