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. |

DETAILED DESCRIPTION The invention claimed is: 1.
A motor-actuable valve for influencing the cross section of a fluid duct, the valve including a shaft which is hollow over at least part of its axial length to define a hollow part in which is arranged a reduction gear motor for rotating the shaft, the hollow part of the shaft forming an output wheel driven by the motor, the shaft comprising a substantially solid region of small diameter and the hollow part which axially follows the substantially solid part, the hollow part defining a bowl open in the manner of a blind hole of substantially larger diameter than the substantially solid part for receiving the motor, wherein the substantially solid part and the hollow part together generally form a tulip shape.
2.
The valve as claimed in claim 1, characterized in that the shaft and an installation housing for both the motor and the reduction gear are produced by plastic injection molding.
3.
A motor-actuable valve for influencing the cross section of a fluid duct, the valve including a shaft which, over at least part of its axial length is widened and hollow to define a bowl in which is arranged a reduction gear motor for rotating the shaft, the widened hollow part of the shaft forming an output wheel driven by the motor, the shaft comprising a first end portion journaled in a first side wall portion of the duct, and a second end portion defining the widened hollow part, the motor disposed in an insulation housing which is disposed coaxially within the bowl defined by the widened hollow part, the insulation housing being held on a second side wall portion of the shaft located opposite the first side wall portion, the widened hollow part being connected to the insulation housing.
4.
The valve as claimed in claim 3, characterized in that the motor is held in an installation housing and the latter is held in the side wall of the duct by means of a collar, with an assembly orifice of that duct being closed.
5.
The valve as claimed in claim 4, characterized in that a latching connection is provided between the installation housing and the valve shaft
