Apparatus for the introduction of air and/or sealant into a tire

Abstract

Apparatus for introducing air and/or sealant into a tire includes a container for the sealant having an inlet and an outlet, wherein the outlet is connectable to the inlet end of a hose whose outlet end is connectable to the tire to be filled and includes a pressure generation means which can be selectively connected to the inlet of the container or to the inlet end of a hose whose outlet end can be connected to the tire to be filled. The same hose is provided for the connection between pressure generation means and the tire to be filled, on the one hand, and between the outlet of the container and the tire to be filled, on the other hand, with respective couplings being provided at the pressure generation means, the inlet of the container, and the outlet of the container and at the inlet end of the hose which selectively enable the inlet end of the hose to be connected directly to the pressure generation means or the inlet of the container to be connected to the pressure generation means and the inlet end of the hose to be connected to the outlet of the container.

1 . An apparatus for the introduction of air and/or sealant into a tire, said apparatus comprising;
 a container for the sealant which has an inlet and an outlet, wherein the outlet can be connected to the inlet end of a hose having an outlet side that can be connected to the tire to be filled; and   a pressure generation means which can be selectively connected to the inlet of the container or to the inlet end of a hose having an outlet end that can be connected to the tire to be filled,   wherein the hose can be connected between the pressure generation means and the tire to be filled, as well as between the outlet of the container and the tire to be filled,   wherein couplings are provided (i) at the pressure generation means, (ii) at the inlet of the container, (iii) at the outlet of the container, and (iv) at the inlet end of the hose, which couplings selectively (a) allow the inlet end of the hose to be connected directly to the pressure generation means or (b) allow the inlet of the container to be connected to the pressure generation means and simultaneously the inlet end of the hose to be connected to the outlet of the container, and   wherein said apparatus contains no switch valve.   
     
     
         2 . An apparatus according to  claim 1 , wherein said tire is a motor vehicle tire. 
     
     
         3 . An apparatus according to  claim 1 , wherein the pressure generation means is either an electric pump or a compressor. 
     
     
         4 . An apparatus according to  claim 1 , wherein the couplings that are provided for the connection of the pressure generation means to the inlet of the container and for the connection of the outlet of the container to the inlet end of the hose are identical. 
     
     
         5 . An apparatus according to  claim 1 , wherein the couplings are plug-in connection couplings. 
     
     
         6 . An apparatus according to  claim 5 , wherein the pressure generation means, the inlet and of the outlet of the container, and the inlet end of the hose have connection stubs that are plugs or sockets for a plug-in connection. 
     
     
         7 . An apparatus according to  claim 3 , wherein a coupling plug is provided at the inlet end of the hose which can selectively be plugged into a matching coupling socket at the pressure generation means or into a matching coupling socket at the outlet of the container. 
     
     
         8 . An apparatus according to  claim 5 , wherein O-rings are provided at the couplings to seal the plug-in connections. 
     
     
         9 . An apparatus according to  claim 1 , wherein locking devices are provided so that the couplings can be latched in a coupled state. 
     
     
         10 . An apparatus according to  claim 1 , wherein a removal unit is provided which has a connection stub for coupling for the inlet and the outlet of the container. 
     
     
         11 . An apparatus according to  claim 10 , wherein the removal unit is releasably connected to the container. 
     
     
         12 . An apparatus according to  claim 10 , wherein the removal unit can be screwed onto the container. 
     
     
         13 . An apparatus according to  claim 10 , wherein the connection stub for the outlet of the container is arranged offset by 180° with respect to the connection stub for the inlet of the container at a housing of the removal unit. 
     
     
         14 . An apparatus according to  claim 10 , wherein the removal unit is arranged at the lower end of the container in the position of use of the apparatus. 
     
     
         15 . An apparatus according to  claim 1 , further comprising a pressure store or a pressure regulation system, wherein a coupling is formed at the inlet end of the hose for the connection to the pressure store or pressure regulation system. 
     
     
         16 . An apparatus according to  claim 1 , wherein a housing is provided for the reception of at least some of the apparatus components. 
     
     
         17 . An apparatus to  claim 16 , wherein the housing forms a pedestal for the container. 
     
     
         18 . An apparatus to  claim 16 , wherein a cut-out is provided at a side of the housing into which a removal unit connected to the container can be plugged.
