Abstract
A tandem brake booster (10) having first (24) and second (28) walls that move in opposite directions within a cavity to produce an output force. A lever arrangement (48) attached to the second (28) wall engages a fulcrum (70) to transfer a force produced by movement of the second wall (28) into the first (24) wall. A control mechanism (72) has a cylindrical body (74) with an annular surface (78) that engages the lever arrangement (48). The movement of the cylindrical body (74) as compared to the output member (41) is a function of the ratio of the distance from the fulcrum (70) to end (46) and from the fulcrum (70) to the annular surface (78), and as such, maximum output travel can be achieved without requiring a corresponding input travel.
