Abstract

A housing having at least one valve seat for at least one flap, which is supported so it can rotate on a drive shaft. The drive shaft is guided on at least one side through the housing, a sleeve, through which the drive shaft is rotatably guided, being disposed fixed in place on the inside of the housing in this area. The sleeve has a first area, which faces the flap and encloses the drive shaft with a first slight play. Furthermore, the sleeve has a second area, which faces away from said flap and has a diameter expansion in comparison to the first area and which, on the front side thereof facing away from the flap encloses the drive shaft with a second slight play. Furthermore, the valve is a gas recirculation valve of a motor vehicle.
