<p>An input force applied to the input rod (18) of the control apparatus (12) according to the invention simultaneously moves the stems (82, 88) to initially interrupt communication between chambers (74, 78) and a reservoir (84). Thereafter, further movement of stems (82, 88) move balls (67, 67´) away from valve seat members (50, 54) and allows metered pressurized fluid to be communicated to the first (16) and second (16´) set of wheel brakes to effect a primary brake application. In response to dynamic conditions sensed by a CPU (17), solenoid valves (21, 25) are activated to allow pressurized fluid to move the first (50) and second (54) valve seat members into corresponding engagement with first (72) and second (76) plunger means to initially interrupt communication between chambers (74, 78) and reservoir (84). Thereafter, further movement of the first (50) and second (54) valve seat members allows metered pressurized fluid to be communicated to the first (16) and second (16´) set of wheel brakes to effect a secondary brake application and attenuate a dynamic condition experienced by the vehicle.</p> |
