• valve and distributor unit should also allow a direct connection between the compressor and tire, which can only be inflated without filling of sealant of the tire.
• the usually sealed sealant bottle is screwed onto the valve and distributor unit in the storage state.
• unscrewing or placing the seal will break it open and the sealant container / sealant bottle will automatically be ready for operation.
• the compressor is switched on by the operator.
• this time-delayed switching on of the compressor can now cause minor problems.
• the tire sealant contained in the sealant container / in the sealant bottle may also be moved against the intended flow direction. This could be done e.g. when tilting the system from its usual rest position or from the intended state. But flows now tire sealant against the intended flow direction in the compressor, it could be damaged during later operation.
• a check valve is usually used in the prior art or an extended air path is provided between the sealant bottle and the compressor.
• valve and distributor unit which reversibly closes the connections / connection channels between the sealant container and the compressed air source depending on the position of the valve and distributor unit.
• valve ball In the intended operating position no sealant reflux takes place and the valve ball releases the air channel. If the system or the device for sealing and inflation is tilted together with the valve and distributor unit, e.g. towards the compressor outlet, sealant could flow into the compressor outlet s. This is prevented by the valve design according to the invention and the compressor outlet s is closed. Pressurization on the side of the air channel presses the valve even more firmly on the valve seat. The valve is thus closed and a sealant return flow is prevented.
• this is arranged in a device according to the invention, which is formed with a compressor as a compressed air source, the valve and distributor unit between the outlet of the sealant container and the outlet valve of the compressor.
• the said position-dependent closing of the valve is particularly well realized when the valve seat is on the side of the compressed air source or the outlet valve of the compressor.

As a result, the reversible closing function is also supported or reinforced by a flow force and the functioning of the device is further improved.
• a further advantageous embodiment is that the surface of the valve seat or the valve body have roughnesses or depressions, which allow a flow through the closed valve depending on the medium density. This results in a pressure measurement in the system, i. in the areas before and behind the
