Abstract
A diaphragm for a turbo charger actuator includes a layer of fabric having upper and lower surfaces. A first layer of elastomeric material coats at least a portion of the upper surface of the fabric to prevent pressurized air from passing through. A second layer of elastomeric material coats at least a portion of the lower surface of the fabric to form a plurality of ribs thereon. The ribs reinforce the fabric and prevent dirt or other abrasive particles from wearing holes in the elastomeric material and the fabric. When the fabric has woven strands, the ribs protect some of the points where the strands intersect in key areas on the diaphragm.
