ートバルブアクチュエータ。A drive rod connected to a wastegate valve, a diaphragm fixed to the drive rod, a housing having a pressure chamber formed by the diaphragm inside, and a spring disposed within the housing to bias the diaphragm. When the supercharging pressure supplied to the pressure chamber exceeds a set value, the diaphragm is displaced against the biasing force of the spring, and the wastegate valve actuator that holds the wastegate valve in the open position °
In the eta, a shape memory alloy is used as the material of the spring, and the temperature characteristics of the spring made of the shape memory alloy are such that the mounting load is small when the temperature is below the set temperature, and the mounting load is large when the temperature is above the set temperature. Characteristic wastegate valve actuator.
