摘要： Disclosed is a throttle device for an internal-combustion engine, in which, on one side of the side wall of a throttle body, there are formed a space for mounting a reduction gear mechanism which transmits the power from a motor to a throttle valve shaft and a default opening setting mechanism for holding a throttle valve opening at a specific opening (default opening) when the ignition switch is in off position, and a gear cover mounting frame which edges the mounting space. The frame is formed lower than the mounting level of the reduction gear mechanism. A gear cover for covering the gear mounting space is attached on the frame. A stopper for defining the default opening and a stopper for defining the full-closed position of the throttle valve are juxtaposed so as to enable position adjustments in the same direction. These stoppers serve to stop a default lever and a throttle gear, thereby enabling downsizing, weight reduction, and rationalization of fabrication and adjustments of an electronically controlled throttle device.

摘要： A throttle valve is rotatably mounted to a throttle body through a throttle shaft. An internal bore shape of the throttle body is of a straight bore type having a shape in which the center of rotation of the throttle valve is placed on the central line of the throttle body. Spherically-shaped internal profile portions are provided in an idle control region lying in the neighborhood of a fully-closed angle of the throttle valve. Further, spherically-shaped internal profile portions are provided as regions following the spherically-shaped internal profile portions referred to above. Moreover, regions each formed by a spherical shape and a composite surface profile of a cylindrical surface substantially parallel to the flow of intake air or regions each formed by a conical surface profile are provided as regions following the spherically-shaped profiles. Incidentally, the center of each spherical profile is offset on the central line of the bore in upward and downward directions. As a result, a clearance defined between each spherical profile and the throttle valve increases as the degree of opening of the throttle valve increases. When the present invention is used in an electronically-controlled type throttle valve control device, the engine speed is set so as to be changed 20 rpm when the throttle valve is opened 0.1° in a low degree-of-opening region of the throttle valve. Therefore, idle control exercised by an ISC valve is unnecessary.

摘要： To achieve an integration of components and the rationalization of the default opening mechanism of the throttle valve, a reduction of the load of the motor drive and a stabilization of the throttle control operation. In a default opening setting mechanism with which the default opening of the throttle valve 24 is maintained to be larger than the fully closed position when the electric current does not pass through the motor 12 driving the throttle shaft 18, the throttle lever 3 and the sleeve 45 are inserted and fixed, and the sleeve 42 united together with the return lever 2 is engaged with the sleeve 45 so as to be enabled to rotate in relative to the sleeve 45. The sleeve 42 is energized by the return coil in the close direction of the throttle valve 24 up to the initial opening position. This energized operation enables the return lever 2 to be coupled with the sleeve 3. A force for opening the valve for keeping the default opening the throttle valve 24 is energized by the spring 5 onto the throttle shaft 18 near the fully closed position.
