摘要： A valve control apparatus sets a certain soft landing start target position to a drive control unit for carrying out driving of a DC motor 2 as a target open position in response to a fully close command, and sets the target open position which the valve control apparatus acquires by gradually decreasing the soft landing start target position to the above-mentioned drive control unit at a time when the difference between an actual open position and the soft landing start target position becomes equal to a first threshold.

摘要： An assembly method includes a step of press-fitting a second valve 27 to a valve shaft 29 to which a first valve 25 is press-fitted and secured while measuring and adjusting a distance L2 so that it becomes equal to a distance L1. Thus, the first valve 25 and second valve 27 are press-fitted to the valve shaft 29 and those components are swaged together so that the first and second valves are secured to the valve shaft, and oil is placed in a press-fitted portion. When components, such as the first valve 25, are sintered parts, oil contained in the sintered parts themselves is used for increasing a joining force that occurs in the press-fitted portion.

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。
