    Abstract: 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.

    Abstract: 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.

    Abstract: 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.

    Abstract: 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.
