ABSTRACT:
A control actuator for a turbocharger comprises an actuator rod coupled within an actuator housing to a pressure responsive diaphragm biased by a spring, and projecting out of the housing for connection to a turbocharger wastegate valve. A seal assembly on the rod accommodates sealed axial rod displacement, and includes a spherical seat maintained by a second spring in relatively low pressure pivotally sealing relation with the housing.
