Abstract
A servomotor having a metal backing plate for a diaphragm which separates the interior of a front shell and a rear shell into a front chamber and rear chamber. The metal backing plate is attached to a hub which extends through the rear shell. The hub has an axial bore with a first passageway which is connected to the front chamber and a second passageway which is connected to the rear chamber. A control means is retained in the axial bore by the metal backing plate being attached to the hub. When the control means is actuated, fluid under pressure enters the rear chamber and creates a pressure differential. The pressure differential develops a force across the diaphragm which is directly transmitted through the backing plate to an output push rod.
