Throttle valve controller for internal combustion engine

A throttle valve controller for an internal combustion engine, comprising:

• an actuator for operating a throttle valve to be opened and closed;
• a driving force connection/disconnection apparatus provided between an opening/closing drive member of the throttle valve and a driving force output member of said actuator;
• the throttle valve being capable of operating to be opened and closed by the operation of an accelerator pedal when said actuator is disconnected from said opening/drive member of the throttle valve;
• and
• a fluid driving force transmitter provided at a driving force connection between a ember displaced with the operation of the accelerator pedal and said opening/driving member of the throttle valve;
• wherein a difference between an opening of the throttle valve controlled with said actuator and another opening to which the throttle valve is to be set by the operation of the accelerator pedal is absorbed by said fluid driving force transmitter.

A throttle valve controller for an internal combustion engine, comprising:

• an actuator for operating a throttle valve to be opened and closed;
• a driving force connection/disconnection apparatus provided between an opening/closing drive member of the throttle valve and a driving force output member of said actuator;
• the throttle valve to be opened and closed being configured to operate via an accelerator pedal when said actuator is disconnected from said opening/closing drive member of the throttle valve;
• and
• a flexing driving force transmitter provided at a driving force connection between a member displaced with the operation of the accelerator pedal and said opening/driving member of the throttle valve;
• wherein a difference between an opening of the throttle valve controlled with said actuator and another opening to which the throttle valve is to be set by the operation of the accelerator pedal is absorbed by said flexing driving force transmitter.

A throttle valve controller for an internal combustion engine, comprising:

• an actuator for controlling opening/closing positions of a throttle valve;
• a driving force connection/disconnection apparatus provided between an opening/closing drive member of the throttle valve and a driving force output member of said actuator;
• a flexing driving force transmission mechanism for connecting a member displaced with the operation of the accelerator pedal and said opening/closing drive member of the throttle valve;
• said flexing driving force transmission mechanism absorbing a difference between an opening of the throttle valve controlled with said actuator and another opening to which the throttle valve is to be set by the operation of the accelerator pedal;
• and
• said throttle valve being capable of operating to be opened and closed by operation of an accelerator pedal when said actuator is disconnected from said opening/closing drive member of the throttle valve by said driving force connection/disconnection apparatus;
• wherein a fully closed position of the throttle valve determined by said opening/closing drive member of the throttle valve is set so as to avoid attaining the maximum return position of said member displaced with the operation of said accelerator pedal.
