摘要： PROBLEM TO BE SOLVED: To provide a throttle body capable of suppressing size of a clearance to about the same size as conventional size by making amount of thermal deformation in a scope from very low temperature to temperature exceeding 100°C of a bore and a throttle valve substantially the same and realizing high performance at low cost.
SOLUTION: Coefficient of linear expansion in the radial direction is brought close to the bore 4 by setting orientation of filler in resin in the circumferential direction. For this reason, the orientation of the filler 2 is set in the circumferential direction by arranging a groove 17 concentrically. The throttle valve 1 with the filler orientated in the circumferential direction can be obtained by impregnating an aggregate constituted by arranging the filler in the circumferential direction into resin and then heating and hardening it. A rib 28 is arranged near the throttle valve shaft to control the molding contraction, which can make the circularity of the bore 4 small.

摘要翻译：要解决的问题：提供一种节气门体，其能够通过在超过100℃的极低温度至超过100℃的范围内使热变形量从而将间隙尺寸抑制为与常规尺寸大致相同的尺寸节流阀基本相同，低成本地实现高性能。
解决方案：通过设置树脂中的填料在圆周方向上的取向，使径向线性膨胀系数靠近孔4。为此，通过同心地布置槽17来将填料2的取向设定在圆周方向上。具有沿圆周方向取向的填料的节流阀1可以通过将由圆周方向排列填料构成的骨料浸渍在树脂中，然后进行加热硬化而获得。肋28布置在节流阀轴附近以控制模制收缩，这可以使孔4的圆度小。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To reduce the burden of driving a throttle actuator and stabilize a control action of a throttle, by improving characteristics (improvement in spring characteristic of a return spring or the like) of a throttle device having an initial opening setting mechanism. SOLUTION: The throttle device has the initial opening setting mechanism for keeping initial opening of a throttle valve 24 to be larger than a full close position when the current is not applied to a motor 12 of the throttle device. The throttle device has an energizing means 4 energizing the throttle valve to a closing direction in an opening region larger than the position of an initial opening setting stopper, and an energizing means 5 energizing the throttle valve 24 to an opening direction to maintain the initial opening in a vicinity of the full close position. A shaft torque T1 applied to a throttle valve closing direction at the position of the initial opening setting stopper by the energizing means 4, and a shaft torque T2 applied to a throttle valve opening direction by the energizing means 5, satisfy the following expressions: T1≥Mf×Ge+Vf, and T2≤Mf×Ge+Vf (where, Mf is motor static friction torque, Ge is a deceleration rate, and Vf is torque required on the throttle shaft to open the throttle valve).

摘要： An adjusting mechanism is provided for the fully-shut position of the throttle butterfly (24), while a second mechanism maintains the latter in a wider-open position while no current is supplied to the motor (12). A component (42) of the latter mechanism turns on the butterfly spindle (18), and is forced by a first device (4) in the shutting direction, engaging with a component (3) fixed to the spindle. A stop (6) prevents the component (42) turning in the shutting direction beyond the initial-opening position. A second device (5) generates an opening force at the fully-shut position of the butterfly, holding it in the initial-opening position. Beyond the latter position, the component (42) is turned with the spindle, which supports it.

摘要： A throttle body as a part of an intake system capable of eliminating such problems that a weight and a cost must be reduced using a resin, the coefficient of linear expansion and thus the amount of thermal deformation varies due to a difference in orientation of filler relative to a bore even if the resin of the same material is used for a throttle valve because a clearance between the bore and the throttle valve of the throttle valve must be reduced to 80 to 100 νm or less, and the roundness after forming may be deteriorated due to a difference in shrinkage and thus an interference or excessive clearance may occur between the bore and the throttle valve, wherein the coefficient of linear expansion in radial direction is brought closely to that of the bore (4) by disposing grooves (17) concentrically so as to dispose the filler (2) in the resin in circumferential direction, and a bulk material formed by disposing the filler in circumferential direction is impregnated with the resin and then heat-cured, whereby the throttle valve (1) having the filler disposed in circumferential direction can be provided, and also the roundness of the bore (4) can be reduced by disposing a rib (28) near a throttle valve shaft so as to control the amount of form shrinkage.

摘要： PROBLEM TO BE SOLVED: To achieve reduction of a burden for driving a throttle actuator, and stability of throttle control action, by normally rotating a fitting member integrally with a throttle shaft while being mounted on the throttle shaft, in an operational range of more than the initial opening of a throttle valve. SOLUTION: An initial opening setting mechanism is equipped with a sleeve 42 with a lever 2, which is rotatively fitted to one end of a throttle shaft 18 against a shaft. Also, the initial opening setting mechanism is equipped with first energizing means 4 by which the sleeve 42 with the lever 2 is energized in the closing direction of a throttle valve 24, second energizing means 5 by which opening force for retaining an initial opening is applied to the throttle shaft 18, and so on. The sleeve 42 with the lever 2, which is used for driving the throttle shaft 18, is integrally rotated with a sleeve 45 while being mounted on the throttle shaft 18, in most of owning ranges from an initial opening position to a throttle fully owning position. Hereby, friction between the sleeves 42, 45 can be almost eliminated.
