Claims

[Scope of utility model registration request]

(1) A turbo supercharger 4 in which an exhaust turbine is arranged in the exhaust pipe 3, a blower for supercharging intake air is arranged in the intake pipe 2, and the rotors 5 and 6 of each of the exhaust turbine and the blower are connected to each other. In the engine 1, the exhaust pipe 3 is provided with an exhaust passage 8 that bypasses the exhaust turbine via an exhaust relief valve 9, and the exhaust relief valve 9 is controlled to open and close by an electronically operated actuator.
A signal for controlling the actuator is generated by inputting and calculating various operating parameter signals of the engine 1, including absolute pressure in the intake pipe 2 downstream of the blower, exhaust temperature, and speed of a vehicle driven by the engine 1. It is characterized by being equipped with an electronic control circuit 18 for outputting, and maintaining the absolute pressure in the intake pipe 2 on the downstream side of the blower, the exhaust temperature, and the vehicle speed below a set maximum value by controlling the opening and closing of the exhaust relief valve 9. Control device for exhaust relief valve of turbocharger.

(2) The utility model registration claim No. 1, wherein the electronically actuated actuator is a control motor 24.
) A control device for an exhaust relief valve 9 of a turbocharger 4 as described in item 4.

(3) The control device for an exhaust relief valve of a turbocharger according to claim (2), wherein the control motor 24 is a stepping motor.

(4) The control device for an exhaust relief valve of a turbo supercharger according to claim (2), wherein the control motor 24 is a DC motor.

(5) The control device for an exhaust gas relief valve of a Tahoe supercharger according to claim 1, wherein the electronically actuated actuator is a diaphragm device whose duty is controlled by a three-way solenoid valve 15.
