    摘要: A throttle valve control arrangement for an internal combustion engine comprising: a throttle valve; an electrical motor for actuating the throttle valve; mechanical links for coupling and decoupling the electrical motor with the throttle valve; a throttle position sensor for detecting a position of the throttle valve; and a control unit which compares an output signal from the throttle position sensor representing a detected throttle position with a signal representing a target throttle valve opening degree and generates a feed-back control signal for the electrical motor based on the comparison result, wherein the throttle position sensor shows a first output voltage characteristic with respect to throttle valve opening degrees for a first region covering ISC and FIC and a voltage gradient of the first output voltage characteristic is selected larger than that of an unmodified output voltage characteristic of the throttle position sensor, thereby a high resolution of the throttle position sensor is obtained for the first region.

    摘要: A throttle actuator comprising: a body which forms an intake passage; a throttle valve shaft; a throttle valve which is connected to the throttle valve shaft and which adjusts the opening of the intake passage; and a motor which applies torque to the throttle valve shaft. The throttle valve is provided with: a valve shaft lever; an accelerator lever which is operated by means of the accelerator pedal; a floating lever which is positioned between the valve shaft lever and the accelerator lever and which transmits torque to the valve shaft lever in such a direction that the throttle valve opens; a valve returning spring which applies torque to the throttle valve shaft in such a direction that the throttle valve closes; a coupler spring which pulls the accelerator lever and the floating lever toward each other; and an accelerator lever returning spring which applies torque to the accelerator lever in such a direction that the throttle valve closes. A difference between the amount of operation caused by the action of the accelerator pedal and the amount of operation caused by the motor is offset by the relationships between the set positions of floating lever and the coupler spring and between the set positions of the floating lever and the valve shaft lever.

    摘要: There is disclosed an electrically-operated actuator in which a throttle valve is driven by a combination of the rotation of a motor and the operation of an accelerator by the operator, and besides the rotational force of the motor is not so transmitted to an accelerator pedal. This actuator is further provided with a fail-safe function. A parallelogrammic link is constituted by a link member fixedly mounted on a throttle shaft, a link member rotatably mounted on the throttle shaft and operatively connected to the accelerator pedal via a wire, a link fixedly mounted on a shaft rotatably mounted on the link member, and a link member connected to the link members by pins. The throttle shaft is coaxial with a shaft of the motor. A gear in mesh with a gear fixedly mounted on the motor shaft is fixedly mounted on the shaft, thereby forming a differential gear mechanism. Forces of springs act respectively on the throttle shaft and the link member in a direction to close the throttle valve. In order to prevent excessive opening and closing of the throttle due to the run-away of the motor, stoppers limit the angle of rotation of the motor.
