Title:
OPERATION APPARATUS OF THROTTLE VALVE
Document Type and Number:
Japanese Patent JPS6332134
Kind Code:
A
Abstract:
An actuating device is proposed which is used to adjust a throttle valve disposed in the intake tube of an internal combustion engine. The actuating device includes a gas pedal adapted to engage an actuating lever, which is supported rotatably relative to a throttle valve shaft, so as to pivot counter to the force of a restoring spring. Connected to the actuating lever is a follow-up drawing spring, which is secured with one end to an intermediate lever provided with a cam disk having a curved camming surface which surface a lever arm is supported so as to operate a damper element. The intermediate lever is rotatably supported with respect to the throttle valve shaft and with a coupling stop engages a throttle valve lever, which is connected to the throttle valve shaft such that relative rotation between them is prevented. The throttle valve lever is drawn against the coupling stop by means of an uncoupling spring disposed between the intermediate lever and the throttle valve lever. An idling actuator also engages the throttle valve lever. When the actuating lever is actuated in the clockwise direction, the intermediate lever is drawn in a damped follow-up manner by the follow-up drawing spring to adjust the throttle valve via the throttle valve lever.
