Definitions
- the invention relates to an exhaust gas recirculation control valve for an internal combustion engine with a housing that has an exhaust gas inlet connected to the exhaust system and has an exhaust outlet connected to the air intake system, at least a valve closing element arranged in a flow cross section, which is actuated by a valve pivot axis that is perpendicular to the central axis of the flow cross-section, and with a drive module that the valve pivot axis drives.
- Such an exhaust gas recirculation control valve is known, for example, from EP - A 1 - 1 002 947 known.
- a valve closing member designed as a pivotable flap formed according to a known throttle valve and the same Way connected to the valve pivot axis.
- Special construction engineering Difficulties arise with such a design of the valve closing member, on the one hand to design the valve so that when closed No leakage of exhaust gas occurs and, on the other hand, jamming-free, if possible to ensure smooth pivoting of the valve closing member.
- the object of the invention is an exhaust gas recirculation control valve to create that the above Avoids disadvantage.
- valve pivot axis eccentric with respect to the valve closing member arranged in a plane running parallel to the valve closing member is.
- the valve closing member pivotal movement around the valve swivel axis. It has proven to be particularly advantageous proved that the valve closing member is circular, it is can taper towards the side facing the valve rod, in particular to provide narrow tolerances in the closed position of the exhaust gas recirculation control valve.
- FIG. 1 shows a perspective view of the exhaust gas recirculation control valve according to the invention 1, which is partially cut in the area of a valve closing member 2 is.
- the exhaust gas recirculation control valve has a housing in a known manner 3, in which a drive module, not shown, and a transmission are arranged in a known manner and a valve pivot axis on which the valve closing member 2 is fastened.
- the closing member 2 closes or opens a flow cross section 5, which represents the connection between one Exhaust gas inlet 6 and one connected to the air intake system of the internal combustion engine Exhaust outlet 7.
- valve pivot axis 4 arranged perpendicular to the central axis of the flow cross section 5, however, runs eccentrically with respect to the valve closing member 2 in one to the valve closing member 2 parallel plane. This way, a ensures particularly simple, frictionless pivoting of the flap without that the valve closing element can tilt.
- FIG. 2 now shows schematically four selected pivot positions of the valve closing member 2 around the valve pivot axis 4.
- the four pivot positions are in the present illustration with I (fully closed) over II and III to marked to IV (fully open).
- the easy pivoting is clearly recognizable due to the inventive design of the valve closing member 2 on the valve pivot axis 4.
