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.

Blow-off valve

An adjustment element for a divert-air valve. The adjustment element includes an actuation element which moves translatorily, and a control body which moves with the actuation element. The control body includes a first hollow body and a second hollow body. The first hollow body includes an outer surface which is circumferentially closed so as to define an interior, a first axial end, and an annular plate which extends radially inward from the first axial end. The second hollow body includes a radially outer annular plate which is sealingly fastened in an encircling manner axially to the annular plate of the first hollow body, and a radially inner region in which an outer surface extends in a direction of the actuation element in the interior of the first hollow body.

Adjustment element for an overrun air recirculation valve

An electromagnetic valve for an internal combustion engine includes a housing, an electromagnetic actuator arranged in the housing, the electromagnetic actuator having an electromagnetic armature and a core, a control element which is arranged to protrude axially out of the housing and which is connected to the electromagnetic armature so as to form a movable unit together therewith, the movable unit having a radial recess, and an arrangement which delimits an axial movement of the movable unit away from the core of the electromagnetic actuator. The arrangement includes at least one hook arranged on the housing. The at least one hook engages into the radial recess of the movable unit.

Electromagnetic valve for an internal combustion engine

A divert-air valve for a compressor of an internal combustion engine includes a flow housing with a duct, an actuator, a control body moved by the actuator to control a throughflow cross section of the duct, an armature, openings in the control body, a valve housing with a housing wall, a support ring with a ring-shaped plate and a cylinder wall, and a sealing ring which seals the housing interior with respect to a part of the duct. The armature is connected to the control body. The openings fluidically connect the housing interior to a part of the duct. The valve housing surrounds the actuator and a part of the control body. The support ring bears, via the cylinder wall, radially from the outside against the housing wall. The radial sealing ring lies axially against the ring-shaped plate and bears radially at the outside against the housing wall.

Overrun air recirculation valve for a compressor of an internal combustion engine

A divert-air valve for a compressor of an internal combustion engine includes a flow housing with an inlet, an outlet, and a duct arranged therein, an actuator housing, an electromagnetic actuator with an armature arranged in the actuator housing, a control body which is moved by the electromagnetic actuator so as to close off the duct, a housing interior in which the armature moves, openings arranged in the control body, a connector housing arranged to bear axially against the electromagnetic actuator and to at least partially delimit the housing interior, a first sealing ring arranged on the connector housing, and a second sealing ring which bears against the flow housing on an axially opposite side of the connector housing. The openings fluidically connect the housing interior to the duct. The first sealing ring bears against the electromagnetic actuator.
