Abstract

An overrun-air recirculation valve includes a flow housing having a flow channel, a valve seat, an actuator, an actuating member movable via the actuator, and a control body fastened to the actuating member. The control body has a lateral outer surface having a bearing edge which is placeable onto and liftable off of the valve seat, a flow-on surface arranged on an axial side facing away from the actuating member, and a wall extending radially inwardly from the lateral outer surface. The flow-on surface has a flow-off edge offset axially to the bearing edge so that a first vector extending radially outwardly from the flow-off edge to a nearest point of the bearing edge to a plane spanned by the bearing edge encloses an angle of <15°, and the wall is offset axially to the bearing edge and to the flow-off edge in a direction of the actuating member.
