A sealing system for an exhaust gas recirculation valve, the exhaust gas recirculation valve including a housing and a valve stem disposed in the housing, the sealing system being disposed between the housing and the valve stem in order to prevent exhaust gas from entering a valve body interior. The sealing system includes at least two sealing assemblies. An exhaust gas recirculation valve includes the sealing system, and the sealing system effectively prevents exhaust gas from leaking into the valve body interior, and effectively prevents carbon deposits from sticking to the valve stem or entering the valve body interior, so as to increase the lifespan and reliability of the exhaust gas recirculation valve.

A cam gear for a linear drive device that transforms a rotational movement of a first component into a linear movement of a second component includes a cam trench, having, in a circumferential direction of the cam gear, a first end portion and a second end portion, the cam trench being arranged on an end face of the cam gear. The cam gear is configured as a sector gear, and at least one of the first and second end portions of the cam trench is open.

Cam gear and linear drive device comprising said cam gear

A linear drive device includes: a motor; a speed-reducing transmission stage having: a pinion gear fixedly connected to an output shaft of the motor, and a transmission gear meshing with the pinion gear; a linear transmission stage configured to transform a rotational movement of the transmission gear into a linear movement of an output connecting rod, the output connecting rod being received in a sleeve member so as to only move linearly; a spiral trench arranged on the transmission gear; and a follower received in the spiral trench so as to be movable in the spiral trench. The follower is connected to the output connecting rod via a connector, and the connector is configured as a right-angle member.
