Abstract: A supercharger includes a rotative member that is rotated by an electric motor eccentrically to the center of a casing. A valve is rotatably supported by a periphery of the rotative member. The valve is capable of making contact with a periphery of the rotative member so that an inner periphery of the casing and an outer periphery of the rotative member define an annular space therebetween in a full opening position. The valve is capable of making contact with the inner periphery of the casing to partition the annular space into multiple variable space in a full closing position. Opening degree of the valve is controlled in an intermediate position between the full closing position and the full opening position in accordance with an accelerator position in a low-load operation.

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.

Abstract: A flow control valve comprises a first valve for controlling a radiator flow amount and a second valve for controlling a bypass flow amount. Pressure adjusting passages are respectively provided for the first and second valves for communicating spaces formed at both sides of the respective valves to equalize fluid pressures at both sides, so that a pressure load in an axial direction to the respective valves can be eliminated. As a result, a driving force of an actuator of the flow control valve for directly or indirectly driving the first and second valves can be reduced.

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.
