Claims

[Scope of utility model registration request]

A rotary shaft fixed to one end is a turbine blade provided in the middle of an exhaust flow path that guides the exhaust gas of the engine, and the other end is fixed to an impeller of an air compressor provided in the middle of the air flow path that flows air sent to the engine; A hydraulic drive device that is provided in the middle of this rotating shaft and rotates the rotating shaft by feeding pressure oil, a pressure oil pump that is driven by an electric motor and discharges pressure oil from a discharge port, and this pressure oil pump. The hydraulic piping is connected in series with one end connected to the discharge port of the hydraulic pump and the other end connected to the pressure oil supply port of the hydraulic drive device, and the pressure on the pressure oil pump side is connected to the hydraulic drive A control valve that is closed when the pressure becomes lower than the valve closing pressure corresponding to the pressure required to drive the device, and is opened when the valve opening pressure is higher than the valve closing pressure, and the above-mentioned hydraulic pressure. In the middle of the piping, there is an accumulator installed between the pressure oil pump and the control valve, a detection means for detecting the operating status of the vehicle, and a signal from the detection means is inputted to increase the output of the engine. A supercharging device for an automobile engine, comprising a controller that starts the electric motor when necessary.
