• the air compressors for such breakdown sets for the temporary repair of punctures are usually connected via a connecting piece, namely via the so-called valve and distributor unit with a sealant bottle and the tire to be repaired.
• the valve and distributor unit ensures that compressed air from the compressor in the sealant / sealant bottle is passed and the sealant drives out of the container via also the valve and distributor unit and transported via appropriate connecting hoses in the tire, ie that the sealant in the Tire is pumped.
• the 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 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.
• a disadvantage of using such an additional check valve is that the installation of this check valve prevents accurate pressure measurement in the tire to be repaired. This can pose a security risk to the end user.
• An extended airway increases the material and production costs and has a negative effect on the system performance achieved.
• a cooperating with a valve seat valve is arranged in the valve and distributor unit, which depends on the density and the flow direction of the medium flowing through the connections / connection channels between

• 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. The valve is thus closed and a sealant backflow will be 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.

• a particularly advantageous embodiment of a position-dependent closing valve is that used in the operating state of the container with sealant overhead in the valve and distributor unit, preferably screwed and the valve is designed so that a deviation of more than 20 ° from the overhead position of the Sealant container causes a closing of the valve. This is in the usual
• 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 For example, air is allowed to pass through it while blocking the flow of the sealant, which makes it possible to measure the pressure in the system, ie in the areas in front of and behind the valve, in any operating condition, including a "closed" valve.
