    摘要: The present invention relates to a mounting device for an exhaust gas re-circulation valve which prevents the overheating, due to high temperature exhaust gas, of a stepping motor powering the opening and closing of the valve and the valve main body of an exhaust gas re-circulation valve which opens and closes the exhaust gas re-circulation passage of an engine. The valve body 201 of the exhaust gas re-circulation valve is buried in a component 100 of the engine having a lower temperature than the exhaust gas. In such a way, the high temperature of the exhaust gas may be absorbed, dispersed and radiated and as a result there is no need to provide a separate cooling structure such as a coolant chamber and the overheating of the stepping motor 300 due to high temperature exhaust gas may be prevented.

    摘要: 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.

    摘要: 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.

    摘要: When a valve lift control signal is received from a control unit 10, two coils from amongst the coils 18a-18d in a step motor 18 are excited and an aperture of a valve 14 is regulated. When the aperture regulation of the valve 14 is completed and a fixed period of time elapses, the excitation mode of the step motor 18 is switched from 2-phase to 1-phase.

    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).
