APPARATUS FOR TRANSPORTING COMPRESSED AIR AND/OR SEALANT IN A VEHICLE TIRE AND PORTABLE/TRANSPORTABLE SYSTEM FOR SEALING AND INFLATING VEHICLE TIRES

The invention relates to a device (1) for transporting compressed air and/or sealant into a pneumatic vehicle tire, comprising at least one gas connection (3) for connecting to at least one compressed-air source (24), at least one sealant connection. (2) for connecting to at least one sealant container (6), at least two channels, wherein a first channel is a sealant transport. channel (4) for transporting a sealant dispersion from the sealant connection into a pneumatic vehicle tire and a second channel is a compressed-air transport channel (5) for transporting compressed air to the sealant connection or to the sealant transport channel, wherein the sealant dispersion comprises sealant particles and compressed air as dispersion matrix, characterized in that the device has a movable switchover element (7), wherein the movable switchover element can be moved in the direction of the sealant connection by means of a compressed-air flow coming from the gas connection and has a severing portion (8) for severing a seal. The invention also relates to a portable/transportable system (38) and to corresponding methods and corresponding uses.
