发明名称 Direct acting rotary actuator for a turbocharger variable nozzle turbine
摘要 A axial to rotational motion actuator employs two sets of engaged helical splines on rotational collars provides a large degree of rotary actuation from a relatively short axial stroke to provides efficient non-binding and reduced effort actuator operation. This improved actuation movement makes the actuator assembly both more responsive to a hydraulic activating means, i.e., oil pressure, and enables packaging the actuator assembly in a compact size to optimize available space around a turbocharger and inside of an engine compartment.
