Abstract
A fluid control valve has a port means across which a control element, mounted on a lever, is slidable. An input control arm rotates a cam which imparts linearly-related angular movement to a further lever. A roller is engaged between the two levers and is movable to vary the distances from the pivotal axes of the levers to their points of engagement with the roller. These distances are different on each lever. Movement of the roller thus varies the linear relationship between movement of the input arm and the control element.
