ABSTRACT:
A timing device includes a timing means which effects movement of a motion transmitting member at a selected rate to provide a timed interval of selected duration, upon expiration of which interval a tripping mechanism, operated by the motion transmitting member, provides a positive biasing force for actuating and enhancing the operation of a fluid valve in controlling a fluid circuit. Means is provided for actuating the timing device in response to a relatively short-term activating pulse.
