摘要： An EGR valve device includes a valve housing having one or more exhaust-gas inlet ports and two or more exhaust-gas outlet ports, and forming an exhaust-gas passage communicated with these exhaust-gas inlet ports and exhaust-gas outlet ports; two valve-sheets disposed on the inner peripheral face of the valve housing; a valve shaft assembled into the valve housing; and two valves secured on the valve shaft, and simultaneously abutting on the respective valve-sheets when the valve shaft moved in one direction. It is arranged that the valve housing is formed of material having an axial thermal expansion coefficient larger than that of the valve shaft, and that the distance between the two valve-sheets is set so as to equal with that between the valves at the normal temperature.

摘要： A first magnetic substance and a second magnetic substance are arranged opposite to each other with a gap left therebetween; a holding member being arranged in the gap; a magnetic field generator being secured to the holding member; the generator being arranged adjacent to the first magnetic substance or the second magnetic substance, thereby increasing an magnetic attraction generated by a magnetic force between the generator and the first magnetic substance or the second magnetic substance. A slide between a sliding portion of a supporting member and that of the holding member is permitted only on the magnetic substance side to which the magnetic field generator stands close, which relaxes the requirements of dimensional accuracy such as the height of the holding member.

摘要： 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).
摘要翻译：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。
