Abstract
Abstract A fluid-tight protection system is provided for an electromechanical component in a casing. An insulating absorbent covering layer which has a high capillary absorption capacity is disposed over joints or apertures in the casing requiring sealing. The covering layer is impregnated with a sealing compound which preferably has a thin liquid form during the impregnation. An impermeable film may also be provided to cover the absorbent covering layer.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
77 words
A fluid-tight protection system for an electromechanical component in a casing in which an insulating sealing absorbent covering layer is disposed as a seal over substantially all portions of the casing requiring sealing, said sealing covering layer comprising a fleece material means with high capillary absorption capacity which is impregnated with a sealing compound and which distributes the sealing compound evenly by said high capillary absorption capacity, said sealing compound having a thin liquid form when impregnating.
Claim 2
Dependent Claim
77 words
A fluid-tight protection system for an electromechanical component in a casing in which an insulating sealing absorbent covering layer is disposed as a seal over substantially all portions of the casing requiring sealing, said sealing covering layer comprising a fleece material means with high capillary absorption capacity which is impregnated with a sealing compound and which distributes the sealing compound evenly by said high capillary absorption capacity, said sealing compound having a thin liquid form when impregnating.
Claim 3
Dependent Claim
23 words
A protection system as in claim 1, characterized in that the covering layer has aperture means for receiving projecting portions of the component.
Claim 4
Dependent Claim
29 words
A protection system as in claim 1, characterized in that the covering layer has means for adapting to differences in level in the surface of the component requiring sealing.
Claim 5
Dependent Claim
15 words
A protection system as in claim 1, characterized in that the sealing compound is hardenable.
Claim 6
Dependent Claim
32 words
A protection system as in claim 1, characterized in that the absorbent covering layer is provided as a covering for a surface of the component exposed through an aperture in the casing.
Claim 7
Dependent Claim
79 words
A fluid-tight protection system for an electromechanical component in a casing in which an insulating absorbent covering layer is disposed over portions of the casing requiring sealing, said covering layer comprising a material with high capillary absorption capacity which is impregnated with a sealing compound, said sealing compound having a thin liquid form when impregnating, and the absorbent covering layer being covered with an impermeable film on the side facing away from the portions of the casing being sealed.
Claim 8
Dependent Claim
79 words
A fluid-tight protection system for an electromechanical component in a casing in which an insulating absorbent covering layer is disposed over portions of the casing requiring sealing, said covering layer comprising a material with high capillary absorption capacity which is impregnated with a sealing compound, said sealing compound having a thin liquid form when impregnating, and the absorbent covering layer being covered with an impermeable film on the side facing away from the portions of the casing being sealed.
Claim 9
Dependent Claim
24 words
A protection system as in claim 6, characterized in that the impermeable film is provided with a filling aperture means for the sealing compound.
Claim 10
Dependent Claim
34 words
A protection system as in claim 7, characterized in that adjacent the filling aperture means a depression, the diameter of which is greater than that of the filling aperture, is provided within the casing.
Claim 11
Dependent Claim
26 words
A protection system as in claim 6, characterized in that the impermeable film is deep-drawn to adapt to the surface of the component to be sealed.

Claim 13
Dependent Claim
66 words
A fluid-tight protection system for an electromechanical component in a casing in which an insulating absorbent covering layer is disposed over portions of the casing requiring sealing, said covering layer comprising a material with high capillary absorption capacity which is impregnated with a sealing compound, said sealing compound having a thin liquid form when impregnating, and the absorbent covering layer being joined to an impermeable film.
Claim 14
Dependent Claim
66 words
A fluid-tight protection system for an electromechanical component in a casing in which an insulating absorbent covering layer is disposed over portions of the casing requiring sealing, said covering layer comprising a material with high capillary absorption capacity which is impregnated with a sealing compound, said sealing compound having a thin liquid form when impregnating, and the absorbent covering layer being joined to an impermeable film.
Claim 15
Dependent Claim
25 words
A protection system as in claim 11, characterized in that an adhesive priming coat is provided between the absorbent covering layer and the impermeable film.
Claim 16
Dependent Claim
