Benefits of technology
The method significantly shortens tire filling time and reduces kit size and weight, achieving up to 100% reduction in leak size without manual tire movement, allowing for more efficient and cost-effective tire repairs.
Problems solved by technology
In the case of tire-related breakdowns, there is generally the problem that—as has hitherto been conventional for example in a passenger motor vehicle—a filled spare tire mounted on a wheel rim must be carried on board, which spare tire is then fitted in place of the wheel with the defective tire, following which the defective tire must be fastened in the stowage space provided in the vehicle for the spare tire and later taken for repair.
For this purpose, it is not only often necessary to unload a laden vehicle in order to access the corresponding stowage space, but it is also necessary for the vehicle itself to be raised using vehicle jacks, and for cumbersome repair work to be performed.
Without a tire movement for distributing the sealant in the tire, sealing of the tire leak is therefore difficult.
This fact contributes significantly to the manufacturing costs of the overall system, and sets a lower limit for the structural size and the weight of tire-related breakdown kits.

Embodiment Construction
[0048]FIG. 1 shows a preferred embodiment of the method parameters for converting the flow into the turbulent range with a Reynolds number Re≥2300. The illustration shows the Reynolds numbers for a sealant according to the invention versus the conveying pressure P and the temperature increase ΔT at the atomizer nozzle. For typical conveying pressures of 200 to 600 kPa the compressor must in this case thus realize an increase of the nozzle temperature of 40 to 60° C. The region enclosed by the dashed line denotes the parameter range for the method according to the invention; the preferred working range according to the invention is the hatched region situated in the boundary of the dashed line.
[0049]The increase of the nozzle temperature is, as presented above, realized by means of an adapted outlet temperature of the air compressor. What is critical for the present application is the cooling of the conveyed air on the path to the tire valve / tire entry valve. The compressed air is co...

Abstract
A method for sealing and inflating inflatable articles, in particular for sealing and inflating motor vehicle tires, wherein, by means of a compressor which is driven preferably by means of an electric motor, a sealing and pumping pressure is generated, wherein, by means of the sealing and pumping pressure, via a valve and distributor device for sealant and compressed gas and via compressed-air and sealant hoses between valve and distributor device and an entry valve or an inlet nozzle of the inflatable article, a sealant situated in a sealant vessel connected to the valve and distributor device is conveyed into the inflatable article and, at the same time, the inflatable article is inflated to a predefined operating pressure, wherein, by configuration of the corresponding parameters, of the sealant and of the device, in or downstream of the entry valve / the inlet nozzle, the sealant is at least partially atomized to form an aerosol by virtue of the sealant or the sealant-air mixture being converted, in the entry valve or in the inlet nozzle, into a turbulent flow with a Reynolds number Re≥22300.
