A mechanical actuator for a diesel transmission modulator spool valve receives a linear input through a cable in response to throttle pedal position. The end of the cable initially moves as lost motion prior to contacting a first end of a spring having a predetermined constant. The second end of the spring acts on an input arm of a lever pivotally mounted in the actuator. An output arm of the lever is at a predetermined angle with respect to the first arm and provides a predetermined mechanical advantage. A linear input movement compresses the spring to provide a directly corresponding, predetermined force at the output arm for use in modulator valve movement. The interior elements of the actuator may be selectively arranged to accommodate an input cable in either a push or pull mode. |
