    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: 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: 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: As a motor is rotationally driven, a valve stem is reciprocally displaced to open or close a flow passage formed in a housing for a high temperature fluid. The motor is held via a bracket where inner surface is concavely recessed contour, and the bracket has a predetermined height and a plurality of openings are formed on the wall surface of the bracket. The housing and the bracket are made integral with each other, and supporting portions formed between adjacent openings are dimensioned to have a smallest cross sectional size necessary from the viewpoint of a strength. With this construction, an efficiency for performing an assembling operation for a motor driven type flow rate controlling valve can be improved, and moreover, a quantity of heat to be conducted from the bracket to the motor side can be reduced.
