The invention relates to a throttle device for the intake section of an internal combustion engine, wherein the throttle device has a multi-part housing that contains a throttle valve device in movable fashion, which can be actuated by means of an actuating drive unit. A base housing, which is embodied as an injection molded component and accommodates the throttle valve device, can also accommodate first housing parts of different flange patterns as interfaces with the intake section and additional second housing parts, which are accommodated so that they can move in relation to the base housing, in order to modify the air conduction.
