Abstract
A servomotor having a partition for separating a first chamber from a second chamber. The partition has a hub with passages therein connecting the first and second chambers with each other and to the atmosphere. The partition has a plurality of concentric annular ribs and radial ribs to strengthen a radial disc that extends from the hub. A valve carried in said hub controls the communication of turbulent free air to the second chamber to create a pressure differential for moving the partition and developing an output force in response to an operator input. This same pressure differential acts on a diaphragm connected to the radial disc to seal a plurality of openings in the radial disc to assure that the pressure differential is not reduced by leakage through the openings.
