Coupling bar for operating control valve of exhaust gas recirculation system, comprises operating unit and exhaust gas control valve, where coupling bar is formed as electrical controller, and ball and socket joint has elastomeric bearing

摘要

The coupling bar (1) comprises an operating unit on one side and an exhaust gas control valve on other side, which are connected by coupling points. The coupling bar is formed as electrical controller, on the side of an operating unit. A ball and socket joint (3) has an elastomeric bearing (2) on the side of the exhaust gas control valve. The ball and socket joint is conducted as temperature resistant bearing and is formed from a molybdenum alloy. The coupling bar is made of aluminum.
