Patent ID: 6938418

Claim:
A turbocharger control system, comprising: an exhaust duct; a turbine disposed within the exhaust duct, the turbine operatively adapted to rotate as exhaust gasses pass through exhaust duct; an exhaust by-pass duct having an inlet and an outlet, the inlet and the outlet being in communication with the exhaust duct, the inlet being in communication with the exhaust duct on an opposite side of the turbine from the outlet; a waste gate disposed within the exhaust by-pass duct between the inlet and the outlet, the waste gate operatively adapted to open and close the by-pass duct; an air duct; a compressor disposed within the air duct, the compressor operatively adapted to be rotated by the turbine; a diaphragm cell including a housing separated into two chambers by a diaphragm, the diaphragm being operatively interconnected with the waste gate such that movement of the diaphragm actuates the waste gate; a valve for controlling air admission into the one of the chambers of the diaphragm cell; and a motor mechanically connected to the valve to control the valve.
