To provide an assembly which is as small as possible which contains a well-protected component and effectively dissipates heat, and to provide a device and a method for use in the rapid manufacture of such an assembly, an assembly includes a component and a housing from which the component is partially separated by narrow casting gaps filled with a casting compound containing a relatively large amount of filler. For the manufacture of such an assembly, a device is used for filling with casting compound and which includes a mounting for securing the assembly in a position which permits air to escape from the casting gaps, which have an external connection during filling. Also there are supply containers and supply lines for the casting compound which open into the casting gaps, and an apparatus for generating pressure. A method which is used to fill narrow casting gaps with casting compound by using such a device. The method involves introducing a casting compound of predetermined viscosity under pressure through the supply lines into the casting gaps, from which the air is displaced.

The device according to claim 2, wherein: the at least one hollow needle has an inner diameter between 0.2 and 2 mm. 4. The device according to claim 1, wherein: the assembly housing includes a tubular sleeve and a base inserted in an end of the tubular sleeve, a second end of the tubular sleeve being open during filling. 5. The device according to claim 1, wherein: the at least one hollow needle is fixable at at least one end of the casting gaps facing toward the opening. 6. The advice according to claim 1, further comprising: a plurality of guide aids to displace the at least one hollow needle in the casting gaps without contacting a component and, when the at least another hollow needle is present, to displace the at least one hollow needle and the at least another hollow needle parallel to one another. 7. The device according to claim 6, wherein: the plurality of guide aids includes a plurality of guide sleeves which are integrated into a tensioning bar. 8. The device according to claim 1, wherein: the at least one hollow needle and the at least another hollow needle include a non-circular cross section which is adapted to a gap geometry perpendicular to a longitudinal axis of the casting gaps. 9. The device according to claim 8, wherein: the non-circular cross section is an ellipsoid. 10. The device according to claim 1, wherein the casting gaps surround the piezoactuator within the housing. 11. A device for filling casting gaps during manufacture of an assembly, comprising: a mounting to securely hold the assembly in a position that, while the casting gaps are filled with a crosslinkable casting compound that contains a filler, permits air to escape from the casting gaps, in dependence upon a filling rate, through an opening in an assembly housing during filling; at least one supply line, for the crosslinkable casting compound, that opens into the casting gaps; at least one supply container for the crosslinkable casting compound; an arrangement for exerting pressure on the crosslinkable casting compound such that the crosslinkable casting compound passes through the at least one supply line; at least one nozzle; and at least one hollow needle, for supply, the nozzle being connected to the at least one supply container for the crosslinkable casting compound and opening into the assembly; wherein: the at least one hollow needle is insertable into at least one continuous borehole in the assembly housing; the assembly is equipped such that a tubular sleeve and a base inserted in an end of the tubular sleeve are included in the assembly housing; the at least one continuous borehole is arranged in a region of the tubular sleeve of the assembly housing in which the base is inserted; an inserted end region of the base provides for the at least one continuous borehole a transport path for a free-flowing medium between a surface region of the base facing toward an inner wall of the tubular sleeve and an end of the base adjoining the casting gaps; the tubular sleeve and the base are brought together into a position such that a connection is formed between the at least one continuous borehole to the transport path associated therewith; and an end of the tubular sleeve facing away from the base is open during filling. 12.
