Abstract: 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.

Abstract: 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.

Abstract: In a DC-motor according to the present invention, contact areas of first brushes can be enlarged without enlarging the external diameter of a disk on which a commutator is provided; therefore, the wear resistance of the first brushes can be enhanced while maintaining a good control-response; and at the same time, the axial dimension can be shortened dramatically, so that the DC-motor can be downsized. The first brushes 14 are radially in contact with the commutator 11, and second brushes 15 are axially in contact with slip rings 12 that are formed circumferentially inside the commutator 11.
