ABSTRACT:
The invention relates to a throttle valve adjusting device (1) which comprises a throttle valve housing (2) linked with a drive unit (6). According to the invention, the electric motor (7) of said drive unit (6) is disposed both outside the housing (9) of the drive unit (6) and outside the throttle valve housing (2) so that its pole tube (16) lies substantially exposed and at the same time serves as the motor casing. Said pole tube (16) has a closed (18) and an open end (17) which is closed by a contact plate (10), while the closed end (18) comprises a bearing element (19) for the drive shaft (14) of the electric motor (7). The inventive throttle valve housing is improved in terms of construction space required and materials used, thereby considerably reducing the costs for production and assembly as well as reducing its weight.
