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： An exhaust gas recirculation valve device is prvided with a motor shaft 32, a stepping motor main body 20 driving the motor shaft 32, a valve shaft 6 having a tip 6a functioning as a proximal end which faces one end of the motor shaft 32 and a distal end provided with a valve 8, a spring 10 pushing the valve shaft 6 in a closing direction, and a spring holder 9 retaining the spring 10. In the case that the valve 8 is closed, the tip 6a of the valve shaft 6 and the spring holder 9 are caulked together at a distance between the tip 6a of the valve shaft 6 and the one end of the motor shaft 32 so that a distance L between the facing ends of the motor shaft 32 and the valve shaft 6 is equivalent to a difference between a stroke of the motor shaft 32 of the stepping motor main body 20 and a stroke of the valve on opening.

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： 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 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).
