    • An exhaust gas re-circulation valve which allows the accurate control of high temperature and pressure exhaust gas flowing through the engine exhaust gas re-circulation passage of a turbo diesel vehicle or the like. Valve seats 28, 29, valves 31, 32 and a valve shaft are mounted on a valve housing 21 and an adjustable adjusting mechanism 36,51,28b,71 is provided which allows both the first valve 31 and the first valve seat 28 and the second valve 32 and the second valve seat 29 to close in abutment by displacement or deformation. In this way even if there is an irregularity in the process or assembly accuracy of the components of the exhaust gas re-circulation valve, it can be absorbed by the adjustable mechanism 36, 51, 28b, 71. As a result the formation of gaps between the valve and the valve seat as a result of irregularities in the in the process or assembly accuracy of the components of the exhaust gas re-circulation valve can be prevented and valve accuracy can be improved.
    • 一种排气再循环阀,其能够精确地控制流过涡轮柴油车辆的发动机废气再循环通路等的高温高压排气。 阀座28,29,阀31,32和阀轴安装在阀壳体21上,并且设置有可调节调节机构36,51,28b,71,其允许第一阀31和第一阀座28和 第二阀32和第二阀座29通过位移或变形而邻接。 以这种方式即使废气再循环阀的部件的过程中存在不规则或组装精度,也可以被可调节机构36,51,28b,71吸收。结果形成间隙 可以防止排气再循环阀的部件的过程中的不规则或组装精度导致阀和阀座之间的差异,并且可以提高阀的精度。

    • An elastic body 51 is provided to absorb impact energy generated by the collision between rotor positioning portions 31 and shaft portion positioning portions 29 when a shaft portion 24 is moved into a female thread portion 26 to determine the initial position of the shaft portion 24, and so the impact noise generated by the collision between the rotor positioning portions 31 and the shaft portion positioning portions 29 can be reduced. Also, the force of impact imparted to the shaft portion positioning portions 29 by the rotor positioning portions 31 decreases, and so it is possible to prevent deformation of the rotor positioning portions 31 and the shaft portion positioning portions 29.
    • 提供弹性体51,以便当轴部分24移动到内螺纹部分26中以确定轴部分24的初始位置时,吸收由转子定位部分31和轴部定位部分29之间的碰撞产生的冲击能量,并且 因此可以减少由转子定位部31与轴部定位部29之间的碰撞产生的冲击噪音。 此外,由转子定位部31向轴部定位部29施加的冲击力减小,因此能够防止转子定位部31和轴部定位部29发生变形。

    • An exhaust gas recirculation system capable of regulating the degree of valve opening with high accuracy in order to properly recirculate exhaust gas to the combustion chamber (1a) of a four-cycle engine (1) for automobiles even in the case of the diesel turbo-type car which usually generates high temperature and pressure exhaust gas. In the exhaust gas recirculation system disclosed herein, two closure valves (19, 20) are provided on the movable shaft (23) so that exhaust gas can flow into a movable space (10a) through openings formed by the movement of the two closure valves (19, 20) in their movable range. The pressure effecting on the two closure valves (19, 20) is canceled out and the movement of the movable shaft (23) is not prevented by high pressure of the exhaust gas. Therefore, even in the case of high temperature and pressure exhaust gas of the diesel turbo-type car or like vehicles, the movable shaft can be driven accurately with a relatively small power stepping motor (17).
    • 一种排气再循环系统,其能够高精度地调节开阀程度,以便即使在柴油机涡轮增压器的情况下也能将废气适当地再循环到用于汽车的四冲程发动机(1)的燃烧室(1a) 通常产生高温高压废气的汽车。 在本文所公开的排气再循环系统中,两个闭合阀(19,20)设置在可动轴(23)上,使得废气可以通过由两个闭合阀的运动形成的开口流入可移动空间(10a) (19,20)处于可动范围。 抵消对两个关闭阀(19,20)的压力被消除,并且通过排气的高压不能防止可动轴(23)的移动。 因此,即使在柴油涡轮式车辆等车辆的高温高压排气的情况下,也可以用相对较小的动力步进电机(17)精确地驱动可动轴。
