Definitions

• the invention relates to a breakdown assistance system for sealing and inflating motor vehicle tires, wherein the breakdown assistance system comprises a compressed gas source, preferably a compressor, and a container for a self-sealing means which can be filled into the motor vehicle tire.
• the container has a container opening located at its upper end and a container connected to the container
• the distributor unit for sealant and compressed gas.
• the distributor unit is designed as a lid for the container opening and is connected both to the compressed gas source
• the inlet line has an inlet valve with a
• Inlet valve body on.
• Vehicles are incomplete or absent or stowed in various places and have to be searched for a long time.
• Compressor a coagulating in the tire sealant, usually a latex milk mixture, the corresponding connection hoses and the necessary cable connections for power supply and switch, pressure gauge and control include and thus provide a constantly deployable and complete repair kit, with the entrainment to a rim mounted spare tire or on the constant control of other repair materials such as hoses, various tool keys,
• Car Jack etc. can be dispensed with.
• repair kits are not easy. Depending on the operating condition, sealant containers and various hose connections must first be connected or rebuilt. Most repair kits are also well suited to this, without the use of sealant only for inflating tires,
• Connector is first connected to the tire valve and still prevails a residual pressure in the tire.
• the residual pressure flowing into the container can cause sealant to escape from the container into the environment, provided that safety caps on the Inlet side of the distributor unit are already solved or not present, or that sealant is transported in the direction of already connected to the distribution unit, but not yet switched on compressor and glued valves there.
• solutions are already known in the prior art that essentially involve a simplified switching from one to the other mode of operation.
• DE 101 06 468 AI discloses a device for dispensing tire sealant from a container, wherein the container is associated with a removal element with a valve which serves for dispensing of tire sealant.
• the valve is designed as a one- or multi-way valve and has a switchable bypass, for example, to operate by a rotary switch, so that in a switching position, a compressed gas source can be connected directly to the tire or the object to be inflated. In another switch position is a connection between
• the object of the invention was to provide a device for sealing and inflating inflatable objects, which provides a secure connection between the sealant container or valve and distributor unit, which allows a simplified application in one or the other mode, the is tolerated easily in faulty connection order in the tire residual pressure and thus safe to handle and in particular has the simplest possible construction with a rugged design and this is easy and inexpensive to manufacture.
• This object is achieved by the features of the main claim. Further advantageous embodiments are disclosed in the subclaims.
