Embodiment Construction

[0016] based on the following figure 1 , figure 2 One embodiment of the air intake control device of the present invention will be described. figure 1 is its longitudinal section, figure 2 yes figure 1 A longitudinal section along line A-A. Additionally, with image 3 Parts of the same construction use the same symbol. The distal end portion 5A of the displacement bearing hub 5 is formed flat, and a guide cylinder portion 5E is formed on the outer peripheral portion thereof along the axial direction of the throttle displacer 3 . On one end of the throttle shifter 3, while forming the matching portion 3A, a matching groove 3B is formed thereunder, and the net drum 9 is fixed at the other end. In this embodiment, the net drum 9 is riveted on the other end of the throttle shifter 3 . The fixing means of net drum 9 is not only limited to riveting, also can be welding. On the casing 7 of the opening sensor S, on the outer peripheral side of the rotor 8 , a cylindrical s...

Abstract

The object of the invention is to provide an intake controller provided with an opening degree sensor and capable of reducing the number of parts, assembly man-our, and manufacturing cost and improving the maintenance property. An engaging part 3A and a fitting groove 3B are formed at one end of a throttle shaft 3. A tip part 5A of a shaft bearing boss 5 is formed into a flat shape, and a guide cylinder part 5F along the axial direction of the throttle shaft 3 is formed at its outer periphery. The fitting groove 3B including the engaging part 3A at one end of the throttle shaft 3 inserted and arranged in a shaft guide hole 6 protrudes from the tip part 5A of the shaft bearing boss 5, and a flat washer W is arranged between an E ring E fitted into the fitting groove 3B and the tip part 5A of the shaft bearing boss 5. The engaging part 3A of the throttle shaft 3 is engaged with and arranged in an engaging hole 8A of a rotor 8 of the opening degree sensor S, a seal cylinder part 7A is guided by the guide cylinder part 5F, and the opening degree sensor S is attached to a throttle body 1.

Description

technical field [0001] The present invention relates to an air intake control device for controlling air or mixture supplied to an internal combustion engine. In particular, it relates to an intake control device having an opening sensor that detects the opening of a throttle valve that controls opening and closing of an intake passage. Background technique [0002] For existing suction control devices by image 3 Be explained. 1 is the throttle body, 2 is the suction passage, the suction passage 2 runs through the inside of the throttle valve body 1, and the throttle shifter 3 that crosses the suction passage 2 is installed with a throttle for opening and closing the suction passage 2. Flow valve 4. The throttle shifter 3 is rotatably held on each shift guide hole 6, and each shift guide hole 6 is penetrated and arranged on the shift bearing hub 5 of the throttle valve body 1, and the shift guide hole 6 is connected with the air suction Passage 2 is relatively formed. I...
