  • Publication number: 20050022780
    Abstract: An air amount control valve is connected to a sidewall of a throttle body in which a main air passage for supplying intake air into an internal combustion engine is formed. The air amount control valve has a bypass air passage bypassing the main passage and controls an amount of air flowing through the bypass air passage, thereby controlling an idling speed of the engine. The air amount control valve includes an aluminum alloy housing having a valve hole and a rotatable valve body having a valve surface facing a fringe wall of the valve hole. To prevent deposits from adhering to the fringe wall facing the valve surface, an anodic oxide film is formed to cover the fringe wall and further a fluororesin film is formed on the anodic oxide film.

  • Patent number: 5890699
    Abstract: An inner periphery of a housing 1 supports a rotary shaft rotatably via a pair of bearings 3, and a valve body 5 which is secured to the rotary shaft 4 changes at least one opening area of an intake port 19 and an outlet port 14 formed in the inner periphery. A biasing member 25 biases the bearings in a one-way direction. Therefore, the valve body 5 is moved or biased by the biasing member to the inner periphery of the collar 2 via the bearings, thereby decreasing leakage in the valve when closing. Therefore, even if difference of the thermal expansion coefficient between the housing 1 and the valve body 5 is significant, the leakage can be decreased, thus increasing variety of the material choice. In addition, even if the difference of the thermal expansion coefficient between the housing 1 and the ball bearings is significant, the bearings may not become loose due to expansion of the collar 2, therefore the housing may be selected from various kinds of material including resinous material.
