- they have the advantage of HO- hen flowability, which leads to a facilitated introduction of the filling material in the air gap as well as high Homoge ⁇ nity and a high dimensional accuracy of the reactor core in the uncured state. Due to the achievable hardness of the filling material also mechanical or acoustic vibrations of the throttle or the throttle core are reliably prevented.
- the inorganic binder comprises at least one type of water-hardened cement.
- the ⁇ ser by adding water in paste form Particularly simply be introduced into the air gap and am ⁇ det then independently to air. In this way, the throttle can be set forth ⁇ particularly simple and inexpensive.
- Such a filling material also offers the advantages of odorlessness, a high temperature and thermal shock resistance, a low toxicity and a chemical stability to oils, Solvents and most organic and inorganic acids.

- the crack ⁇ formation is reliably prevented in the air gap of the inductor core unit of the reactor or in the magnetizable material of reactor core, since the operating temperature fluctuations arising thereby the throttle especially on prolonged loading to a comparable temperature-dependent Expansion behavior of the inductor core or the gap and the filler lead.
- This causes no cracks or mechanical damage to occur and the service life of the throttle core unit or provided with this throttle is considerably extended.
- it is additionally ensured that no disturbing noise emissions at frequencies audible by humans occur during the operation of the throttle.
- the inductor core unit can be particularly quick to be a ⁇ times and inexpensively manufactured by the cement initially with a predetermined amount of water are mixed and is then introduced into the air gap. Due to the good flow properties and metering bility of the filling material, the air gap without additional processing steps ⁇ Liche is filled homogeneously, thereby a particularly high mechanical strength is achieved. The subsequent setting of the cement takes place in air. It can also be provided that the Gremate ⁇ rial is pressed after insertion into the air gap in this. In this way, an at least approximately complete filling of the air gap and a correspondingly high mechanical strength and load capacity of the throttle core unit are ensured.
- a further increase in the mechanical load capacity of the reactor core unit is achieved in a further embodiment in that it is ensured during introduction of the filler or after further processing steps that a frictional connection between the inductor core and a bobbin of the throttle is produced. This can be followed at ⁇ play as replaced by pressing the filler into the air gap or by compressing the reactor core. Excess filling material swells here gege ⁇ appropriate, over and can be easily removed.

- the inductor core parts 12a, 12b are arranged around a coil body 14 of double T-shaped cross-section, which in turn serves to increase inductance of the inductor when it is wound several times with an electrical conductor (not shown).
- an air gap 16 Between the throttle core parts 12a, 12b and the bobbin 14 there is an air gap 16, which has different gap thicknesses in different sections 16a-c.
- a filling material is in the portion 16b of the air gap 16, which forms a ⁇ telpfad With the throttle 18 is introduced ⁇ .
- the choke core 12 is made in the present embodiment of a ferrite and thus has a thermal expansion coefficient ⁇ D , whose value is approximately in the range between ll * 10 ⁇ 6 / K and 12 * 10 ⁇ 6 / K.
- the filler 18 is formed such that there is a Thermal expansion coefficient ⁇ F has, whose value lies in a range of ⁇ 70% of the value of ⁇ bathausdehnungsko efficient ⁇ D of the material of the reactor core 12th In this way, it is ensured that during the operation of the throttle or the throttle core unit 10 alstre ⁇ tende temperature fluctuations to comparable dimensional changes of the throttle core 12 and the air gap 16 on the one hand and the filling material 18 on the other hand loom ⁇ ren. This will cracking and a associated noise generation avoided.
- the filling material 18 may include water-curable cement such as a zirconium-based, which has a thermal expansion coefficient ⁇ F having a value of about 4.7 * 10 "6 / K.
- This filler material 18 has a high e- lectrical insulation, a high resistant ⁇ ness to thermal shock, high Temperaturbe ⁇ permanence and high chemical resistance and is due to its odorless and low To- xiztician easy to handle.
- most inorganic and silicate-based cements are suitable as a filling material 18, as they usually heat from ⁇ expansion coefficients ⁇ F 10 ⁇ have 6 / K with values between about 4.0 * 10 "6 / K and 18.0 *.
