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.

Motor driven value

An electric bus bar for low to medium current magnitudes is produced by co-extruding a support structure and a plurality of strips embedded therein. The material of the support structure is plastic and non-electroplatable, whereas the material of the strip is plastic and electroplatable. After a one-piece support element comprising the support structure and the strips has been formed by the co-extrusion step, exposed surfaces of the strips are electroplated with an electrically conductive material.

Electric bus bar, the use thereof and a method for producing the same

In order to guide supply or construction elements through a harmonic drive ( ) in a central manner, said harmonic drive is embodied in a hollow gear. The harmonic drive directly provides a given correcting translatory variable which is defined by the speed of rotation of the output ring and motor driven harmonic generator when the output ring axially displaces a threaded rod ( ) which freely extends in a coaxial manner through a longitudinal bore in the harmonic drive and engages with said output ring, said axial displacement occurring as a result of the rotational movement of the inner thread of the output ring, whereby the threaded rod is secured to the housing and prevented from rotating ( ). The threaded rod can move in a linear manner in relation to the gear motor ( ) when the gear motor is installed in a stationary manner or when the treaded rod is installed in a stationary manner.

Harmonic drive

The invention relates to a gear motor which is easy to install and which due to its especially flat design can be utilized in various ways also in narrow spaces. To this end, the gearmotor is provided on one side of a wheel-shaped housing base body with an especially short motor and on the opposite side and in a coaxial relation thereto with a reducing gear. The main gear drive element can be configured integrally with the motor shaft and with a circular disk as the line support for the disk-shaped rotor by plastic injection molding. The track of said line support is introduced in the disk surface as an electroconductive lining by way of MID technology.
