Title:
THROTTLE DEVICE OF INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2000/068555
Kind Code:
A1
Abstract:
A throttle device of internal combustion engine, wherein an installation space for a speed reduction gear mechanism which transmits the power of a motor to a throttle valve stem is formed on one of the side wall surfaces of a throttle body, a throttle sensor for detecting a throttle valve opening is incorporated inside a gear cover which covers the installation space so that it is covered by a sensor cover, a shaft hole in a rotor of the throttle sensor is exposed through the sensor cover to the outside and, when the gear cover is installed on the side wall of the throttle body, one end of the throttle valve stem is press-fitted to a rotor shaft hole with an elastic deformation of a spring so as to reduce the size and weight of an electrically controlled throttle device, simplify an assembly and wire harness structure, and stabilize the operation and increase the accuracy of the throttle sensor.
