Abstract
A power valve assembly has a pressure responsive diaphragm acting generally in opposition to spring means for controlling the position of a related contoured valving member; when engine manifold decreases due to increasing engine loads, motion transmitting means associated with the pressure responsive diaphragm operatively engages and causes the valving member to be progressively further opened generally in accordance with the decrease in the magnitude of such engine manifold vacuum.
