Compressor for a Tire Repairing Kit

Abstract

A compressor for a tire-repairing kit contains a second toothed wheel provided with a journal. The journal is functionally connected to a piston in such a way that the piston moves up and down when the second toothed wheel rotates. The inertial forces of the piston carrying out the up and down movement are compensated by a counterweight which is embodied in an integral manner with the second toothed wheel and is fixedly connected thereof.

1 . A compressor for a tire puncture kit, comprising:
 a first gearwheel;   a drive motor driving said first gearwheel;   a shaft;   a second gearwheel mounted rotatably about said shaft and operatively connected to said first gearwheel;   a stub disposed with a parallel offset to said shaft mounting said second gearwheel and rotates about said shaft when said second gearwheel rotates;   a piston having a piston rod connected to said stub such that said piston moves up and down during a rotation of said second gearwheel; and   a balancing weight for balancing inertia forces of said piston moving up and down, said balancing weight connected nondetachably to said second gearwheel.   
   
   
       2 . The compressor for the tire puncture kit according to  claim 1 , wherein said stub and said shaft are elements of said second gearwheel and are connected nondetachably to said second gearwheel. 
   
   
       3 . The compressor for the tire puncture kit according to  claim 1 , wherein said second gearwheel has a cavity formed therein and disposed annularly about said shaft. 
   
   
       4 . The compressor for the tire puncture kit according to  claim 1 , further comprising a bearing for said shaft and selected from the group consisting of ball bearings and rolling bearings. 
   
   
       5 . The compressor for the tire puncture kit according to  claim 4 , wherein said second shaft is a hollow shaft and is connected to said bearing such that said second gearwheel is secured in an axial direction. 
   
   
       6 . The compressor for the tire puncture kit according to  claim 5 , further comprising a screw for producing a connection and said screw being inserted into said hollow shaft, or by flanging said hollow shaft. 
   
   
       7 . The compressor for the tire puncture kit according to  claim 1 , wherein said stub is a hollow stub to which said piston rod is connected such that said piston rod is secured in an axial direction. 
   
   
       8 . The compressor for the tire puncture kit according to  claim 7 , further comprising a screw for producing a connection, said screw being inserted into said stub, or by flanging said stub. 
   
   
       9 . The compressor for the tire puncture kit according to  claim 1 , wherein:
 said second gearwheel is embodied as a cup having an end wall, an outer cup, and an inner cup with an inner cup end wall;   said balancing weight is disposed in said outer cup;   said shaft is fastened concentrically on said inner cup end wall of said inner cup; and   said stub is disposed on said end wall of said cup.   
   
   
       10 . The compressor for the tire puncture kit according to  claim 1 , wherein said second gearwheel is produced by a casting method.
