ABSTRACT:
A pneumatic control for turbochargers includes an evaucated bellows-operated servo valve for controlling the pressure differential across a diaphragm, which in turn controls the position of a turbocharger wastegate valve. Discharge pressure from a turbocharger compressor is applied to both sides of the diaphragm. The bellows-operated servo valve is operable to vent one side of the diaphragm whenever the discharge pressure exceeds a predetermined magnitude resulting in a pressure differential across the diaphragm to control the position of the waste gate valve.
