PCT No. PCT/DE96/01775 Sec. 371 Date Aug. 14, 1998 Sec. 102(e) Date Aug. 14, 1998 PCT Filed Sep. 19, 1996 PCT Pub. No. WO97/32125 PCT Pub. Date Sep. 4, 1997An exhaust gas recirculation valve having a valve member that cooperates with a valve seat of a connection neck of an exhaust gas recirculation line. The neck protrudes into a tube of the intake system of an internal combustion engine, and the valve seat points toward the inlet side of the exhaust gas recirculation line. A valve member of the exhaust gas
recirculation valve is thus acted upon by the exhaust gas pressure in the closing direction, as a supplement to a compression spring counter to an
armature of an electromagnet acting in the opening direction. To compensate for the forces acting in the closing direction, the exhaust gas is carried via a conduit in the valve shaft into a control chamber, which is closed off from the pressure in

摘 要 附 图：
the tube via a movable wall, having an effective surface area that substantially corresponds to the effective surface area of the valve member. This obtains a
balance of forces, such that the control of the exhaust gas recirculation valve depends only on the electromagnetic forces and on the force of the compression spring. 主权项：
