Abstract
A throttle controller includes a main body to which is connected a body cover which accommodates therein a power transmitting mechanism constituted by a pinion gear, a secondary gear, and a final gear. Accommodated in the body cover are a built-in throttle sensor and a lever connecting the throttle sensor and the throttle shaft. The throttle controller is less complicated in construction, requiring a smaller number of parts, and allows realization of reduced production cost as compared to other known constructions. In addition, the assembly of the throttle sensor is easier.
Claims20
A throttle control device comprising;
- a throttle body;
- a throttle shaft journalled on the throttle body;
- a throttle valve accommodated in the throttle body and mounted on the throttle shaft for adjusting an amount of air passing through an intake passage of an internal combustion engine;
- a motor coupled via a power transmission mechanism to the throttle shaft for driving the throttle valve in a closing direction and an opening direction to adjust an amount of opening of the throttle valve, the motor including a case which accommodates a pair of terminals;
- a cover connected to the throttle body and enclosing the power transmission mechanism, said cover including a built-in throttle sensor for determining the amount of opening of the throttle valve, said terminals being fitted into a passage in the cover with the terminals accessible from outside the cover;
- and
- a connecting member connecting the throttle sensor and the throttle shaft.
