チヤージヤの制御装置。 In a control device for a variable displacement turbocharger, the control device includes a variable displacement means provided at a turbine scroll inlet of an exhaust passage to vary a cross-sectional area of the passage, and a diaphragm actuator for driving the variable displacement means, wherein the diaphragm actuator is , by one diaphragm fixed to one rod connected to the capacity variable means.
a positive pressure chamber into which the compressor discharge pressure is introduced; an elastic member that is contracted in the atmospheric pressure chamber and urges one diaphragm toward the positive pressure chamber; and a predetermined gap between the two rods. The atmospheric pressure chamber is divided into two parts by the other diaphragm to which the other rod is fixed, which is slidably housed in the elastic sealing member, a negative pressure chamber into which suction negative pressure is introduced, and a negative pressure chamber. and an elastic member that is contracted to bias the other diaphragm toward the atmospheric pressure chamber. 1. A control device for a variable displacement turbocharger, characterized in that the displacement is caused through a variable displacement turbocharger.
