Abstract
An easy-to-assemble motor-adjustable throttle valve for fluid channels, especially in motor vehicle air conditioning systems, which can be obtained when a geared motor is integrated in the setting stem without causing an unacceptable reduction of the remaining clear channel cross-section. A built-in housing fitted with a high-speed small servomotor and provided with a strongly reducing shaft gear disposed inn the axial extension of the housing is radially inserted through a side wall of the channel and coaxially inserted into a pot-shaped tapered section of one end of the setting stem, the output wheel of the shaft gear being formed on the inner covering surface of such section.
