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≥2300.
