Secondary Air Valve for a Secondary Air System of an Internal Combustion Engine, Internal Combustion Engine and Motor Vehicle

A secondary air valve (64) for a secondary air system (52) of an internal combustion engine (10), comprising:

• a valve housing (66) through which secondary air to be introduced into an exhaust gas system (22) of the internal combustion engine (10) is flowable, wherein the valve housing (66) has:
• a cylindrical housing chamber (68) which is directly delimited by an inner circumferential lateral surface (70) of the valve housing (66);
• an inlet opening (72) via which the secondary air is introducible into the valve housing (66) and into the cylindrical housing chamber (68);
• and
• an outlet opening (76) via which the secondary air is dischargable from the valve housing (66) for introduction of the secondary air into the exhaust gas system (22);
• and
• a valve element (78) which is movable along a movement direction (80) relative to the valve housing (66) between a closed position(S) closing the outlet opening (76) and at least one open position (O) releasing the outlet opening (76);
• wherein the inlet opening (72) is disposed along the movement direction (80) between a first sealing element (90) and a second sealing element (92) via which an outer circumferential lateral surface (94) of the valve element (78) facing towards the inner circumferential lateral surface (70) is sealed against the inner circumferential lateral surface (70) of the valve housing (66);
• wherein the valve element (78) is a plate-shaped or a disc-shaped valve and has a plate-shaped or disc-shaped valve part (86) and has a valve stem (88) to which the plate-shaped or disc-shaped valve part (86) is connected;
• wherein the secondary air valve (64) has a third sealing element (96) via which the plate-shaped or disc-shaped valve part (86) is sealed against the valve housing (66) in the closed position(S);
• wherein the valve element (78) is free from a surface running diagonally or perpendicularly to the movement direction (80) at least on an outer circumference along an entire extension (ER) running between the first sealing element (90) and the second sealing element (92) at least in the closed position(S) along the movement direction (80).
