Abstract
A flap device for an internal combustion engine includes a flow housing which delimits a flow duct, a shaft which rotates, a flap body attached to the shaft in the flow duct, an actuator which rotates the shaft and thereby the flap body in the flow duct, an actuator housing having the actuator arranged therein, a first bearing seat formed on the flow housing, a second bearing seat formed on the actuator housing, a first bearing arranged in the first bearing seat, and a second bearing arranged in the second bearing seat. The shaft projects into the actuator housing. The shaft is mounted at one side via the first bearing and the second bearing.

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;
- 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, the actuator housing comprising a receiving element;
- a first bearing seat formed on the flow housing;
- a second bearing seat formed on the actuator housing;
- a first bearing arranged in the first bearing seat;
- and
- a second bearing arranged in the second bearing seat,
- wherein,
- the shaft is configured to project into the actuator housing,
- the shaft is mounted at one side via the first bearing and the second bearing, and
- the flow housing comprises a protrusion in which the first bearing seat is formed, the protrusion being configured to radially abut against the receiving element of the actuator housing.
