摘要

A modulating valve is urged from its extreme closed position to its extreme open position by one end of a pivoted lever, and the modulating pressure is applied to a piston which acts on the other end of the pivoted lever to lock the modulating valve in its extreme open position until an external force is applied to the lever to move the modulating valve to its extreme closed position.
