摘要： An exhaust gas re-circulation valve which allows the accurate control of high temperature and pressure exhaust gas flowing through the engine exhaust gas re-circulation passage of a turbo diesel vehicle or the like. Valve seats 28, 29, valves 31, 32 and a valve shaft are mounted on a valve housing 21 and an adjustable adjusting mechanism 36,51,28b,71 is provided which allows both the first valve 31 and the first valve seat 28 and the second valve 32 and the second valve seat 29 to close in abutment by displacement or deformation. In this way even if there is an irregularity in the process or assembly accuracy of the components of the exhaust gas re-circulation valve, it can be absorbed by the adjustable mechanism 36, 51, 28b, 71. As a result the formation of gaps between the valve and the valve seat as a result of irregularities in the in the process or assembly accuracy of the components of the exhaust gas re-circulation valve can be prevented and valve accuracy can be improved.

摘要： As a motor (12) is rotationally driven, a valve stem (4) is reciprocally displaced to open or close a flow passage (1c) formed in a housing (1) for a high temperature fluid. The motor (12) is held via a bracket (14) of which the inner surface (14a) has a concavely recessed contour, and the bracket (14) has a predetermined height and a plurality of openings (14b) are formed on the wall surface of the bracket (14). The housing (1) and the bracket (14) are made integral with each other, and supporting portions (14d) formed between adjacent openings (14b) are dimensioned to have the 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 (14) to the motor side can be reduced.

摘要： An exhaust gas reflux device which is capable of accurately adjusting a valve opening to appropriately reflux an exhaust gas to a combustion chamber (1a) of a four cycle engine (1) for automobiles, even if the exhaust gas is a high temperature, high pressure exhaust gas from a diesel turbocar. In the exhaust gas reflux device (8), a movable shaft (23) is provided with two closure valves (19, 20) to allow an exhaust gas to flow into a movable space (10a) from within movable ranges of the two closure valves (19, 20). Accordingly, a high pressure of the exhaust gas constantly act on the two closure valves (19, 20) to be cancelled, and do not interfere with movements of the movable shaft (23), so that despite a high temperature, high pressure exhaust gas from a diesel turbocar, the movable shaft can be moved accurately by a small force of a stepping motor (17).

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.
