摘要： An exhaust gas recirculation control valve device, in which wall surfaces at an inlet of an exhaust gas passage are enhanced in anticorrosion against exhaust gases to suppress deposit of fine particules thereto and significantly reduce frequency of maintenance, and which is excellent in assembling quality and inexpensive. The exhaust gas recirculation control valve device comprises a housing (41) having therein an exhaust gas passage (33), a control valve (7) provided in the housing for controlling an amount of exhaust gases circulated in an intake pipe of an engine through the exhaust gas passage, a shield body (42) formed from a material, which is superior to the housing in anticorrosion against exhaust gases, into a cylinder having a valve seat at a tip end thereof, the valve seat abutting against the control valve, the shield body being mounted at an inlet of the exhaust gas passage to cover an inner wall surface of the inlet of the exhaust gas passage, a valve stem (23) connected to the control valve and slidably arranged relative to a slide member press fitted into the housing, a diaphragm (8) mounted to an end of the valve stem and adapted to be actuated by a pressure difference to open and close the control valve, and a negative pressure casing (14) for forming the pressure difference through the diaphragm.

摘要： An elastic body (51) is provided to absorb the energy of collision generated by the collision of a rotor positioning section (31) against a shaft positioning section (29) when the initial position of a shaft section (24) is to be determined by shifting the shaft section (24) toward a female thread section (26), so that the noise of collision generated when the rotor positioning section (31) hits the shaft positioning section (29) can be reduced. Furthermore, the force of collision the rotor positioning section (31) exerts on the shaft positioning section (29) is reduced to prevent the rotor positioning section (31) and the shaft positioning section (29) from being deformed.

摘要： A device for mounting an exhaust gas reflux valve and preventing a valve disc of an exhaust gas reflux valve which opens and closes an exhaust gas reflux passage in an engine and a stepping motor which drivingly and controlingly opens and closes the valve from being overheated by high temperature heat of an exhaust gas, wherein the valve body (201) of the exhaust gas reflux valve is embedded in that portion of an engine structure (100) where temperature is lower than exhaust gas temperatures. Thus the engine structure can absorb and spread high-temperature heat of the exhaust gas for radiation, and so it is possible to prevent overheating of the stepping motor (300) due to high-temperature heat of the exhaust gas without the need of any special water-cooled construction such as a cooling water chamber.

摘要： An exhaust gas recirculation valve device comprises a motor shaft (32), a stepper motor main body (20) for driving the motor shaft (32), a valve shaft (6) having a smaller diameter portion (6a) at its proximal end opposed to one end of the motor shaft (32) and a valve (8) at its distal end, a spring (10) urging the valve shaft (6) in the valve closing direction, and a spring holder (9) for holding the spring (10). The smaller diameter portion (6a) of the valve shaft (6) is caulked for fixing to the spring holder (9) such that when the valve (8) is in the closed state, the distance (L) between the valve and one end of the motor shaft (32) is equal to the difference between the amount of stroke of the motor shaft (32) driven by the stepper motor main body (20) and the amount of opening of the valve (8).
