COMPACT OVERRUNNING COUPLING AND CONTROL ASSEMBLY HAVING REDUCED PART COUNT AND MANUFACTURING COMPLEXITY

摘要

A compact overrunning coupling and control assembly having reduced part count and manufacturing complexity is provided. An actuator arm moves a control element from a first position which corresponds to a first mode of the assembly to a second position which corresponds to a second mode of the assembly. An actuator piston is disposed within the bore of a housing and has an outer surface in sliding contact with the inner surface of the housing and a groove formed in the outer surface of the piston to receive and retain a free end portion of the actuator arm therein. A control pressure signal within the housing causes the piston to slide within the bore against a biasing force to move the actuator arm.
