A flap device for an internal combustion engine includes a flow housing which delimits a flow duct, a shaft which rotates and which is supported on one side thereof, a flap body attached to the shaft in the flow duct, an actuator which rotates the shaft and thereby the flap body, an actuator housing having the actuator arranged therein, a first bearing seat formed on the flow housing, a first bearing arranged in the first bearing seat to radially surround the shaft, a second bearing, a chamber which surround the shaft, and a bore arranged to open into the flow duct from the chamber. The shaft protrudes into the actuator housing. The shaft is supported on the one side via the first bearing and via the second bearing. The chamber from which the bore opens into the flow duct is arranged between the first bearing and the second bearing.

1. A flap device for an internal combustion engine, the flap device comprising: a flow housing configured to delimit a flow duct;a shaft configured to rotate, the shaft being supported on one side thereof;a flap body attached to the shaft in the flow duct;an actuator configured to rotate the shaft and thereby the flap body in the flow duct;an actuator housing configured to have the actuator be arranged therein;a first bearing seat formed on the flow housing;a first bearing arranged in the first bearing seat so as to radially surround the shaft;a second bearing;a chamber configured to surround the shaft;a bore arranged to open into the flow duct from the chamber;wherein,the shaft is configured to protrude into the actuator housing,the shaft is supported on the one side via the first bearing and via the second bearing, andthe chamber from which the bore opens into the flow duct is arranged axially between the first bearing and the second bearing. 2. The flap device as recited in claim 1, wherein the bore is formed in the first bearing. 3. The flap device as recited in claim 1, wherein the bore is formed in the first bearing seat. 4. The flap device as recited in claim 3, wherein the first bearing comprises a step-shaped widened portion on an axial end thereof, the step-shaped widened portion being formed on a side of the first bearing seat which is opposite to the flow duct so that the bore extends parallel to the shaft from the step-shaped widened portion into the flow duct. 5. The flap device as recited in claim 3, wherein, in an assembled state of the flap device, the bore is formed in a geodetically lower region of the first bearing seat or in a geodetically lower region of the first bearing. 6. The flap device as recited in claim 1, wherein the bore is arranged on a downstream side of the flap body when the flap body is arranged to close the flow duct. 7. The flap device as recited in claim 1, further comprising: a second bearing seat formed on the actuator housing;the second bearing is arranged at a distance from the first bearing in the second bearing seat. 8. The flap device as recited in claim 1, wherein, the flow duct comprises a central axis,the shaft comprises a shaft axis,the flow duct is configured to extend horizontally, andthe bore is arranged in a plane which is spanned by a first vector extending vertically to the central axis of the flow duct and by a second vector extending along the shaft axis of the shaft. 9. The flap device as recited in claim 1, wherein the flap body is formed spherically so that the bore allows for a free flow therethrough in all positions of the flap body, and, in a closed state of the flap body, the bore is arranged on a downstream side of the flap body.
