1. A device comprising:
at least one gas connection configured to connect to at least one compressed-air source,
at least one sealant connection configured to connect to at least one sealant container,
at least two channels, wherein a first channel is a sealant transport channel configured to transport a sealant dispersion from the at least one sealant connection into a pneumatic vehicle tire and a second channel is a compressed-air transport channel configured to transport compressed air to the at least one sealant connection or to the sealant transport channel;
wherein the device has a movable switchover element, and wherein the movable switchover element is movable by a compressed-air flow coming from the at least one gas connection and has a severing portion configured to sever a seal on the at least one sealant connection or a seal on the at least one sealant container fastened to the at least one sealant connection;
wherein the movable switchover element includes a hollow cylinder having an internal channel, wherein the movable switchover element forms, along a vertical extent of the hollow cylinder in cooperation with an inner wall of the compressed-air transport channel, a plurality of portions, wherein the plurality of portions comprise at least the following portions:
a bypass portion configured to conduct compressed air from the compressed-air transport channel into the sealant transport channel without flowing through the internal channel to the at least one sealant connection, and
an activation portion, wherein the activation portion is designed to use compressed air coming from the at least one gas connection to move the switchover element in the direction of the at least one sealant connection.
