Compressor for discharging a medium

Abstract

In a compressor for discharging a medium, in particular tire sealant that is to be discharged from a container into a tire, wherein a motor ( 1 ) of the compressor (P) drives a step-up transmission wheel ( 3, 3.1 ) for moving at least one piston ( 6 - 6.6 ) in a compression chamber ( 7 ), the step-up transmission wheel ( 3, 3.1 ) is intended to be provided only partially on its circumference with a toothing ( 20 ) and/or to consist of two toothed wheels ( 11, 12 ) lying on each other.

1 . A compressor for discharging a medium, in particular tire sealant that is to be discharged from a container into a tire, wherein a motor ( 1 ) of the compressor (P) drives a step-up transmission wheel ( 3 ,  3 . 1 ) for moving at least one piston ( 6 - 6 . 6 ) in a compression chamber ( 7 ), characterized in that
 the step-up transmission wheel ( 3 ,  3 . 1 ) is provided only partially on its circumference with a toothing ( 20 ) and/or consists of two toothed wheels ( 11 ,  12 ) lying on each other.   
     
     
         2 . The compressor as claimed in  claim 1 , characterized in that the step-up transmission wheel ( 3 ) is connected eccentrically to an output wheel ( 4 ) and, by way of the latter, to a piston rod ( 5 ), which moves a piston ( 6 ) in a compression chamber ( 7 ). 
     
     
         3 . The compressor as claimed in  claim 2 , characterized in that the output wheel ( 4 ) consists of two wheel halves ( 4 . 1 ,  4 . 2 ), each with a toothing ( 14 . 1 ,  14 . 2 ), wherein the toothing ( 14 . 1 ) of one wheel half ( 4 . 1 ) extends about one arc distance and the toothing ( 14 . 2 ) of the other wheel half ( 4 . 2 ) extends about another arc distance. 
     
     
         4 . The compressor as claimed in  claim 3 , characterized in that the arc distance is in each case  180 °. 
     
     
         5 . The compressor as claimed in  claim 1 , characterized in that the two toothed wheels ( 11 ,  12 ) lying on each other interact alternately with one or other wheel half ( 4 . 1 ,  4 . 2 ) of the output wheel ( 4 ). 
     
     
         6 . The compressor as claimed in  claim 5 , characterized in that one toothed wheel ( 11 ) has a greater diameter than the other toothed wheel ( 12 ). 
     
     
         7 . The compressor as claimed in  claim 1 , characterized in that the step-up transmission wheel ( 3 . 1 ) interacts with two mutually opposite toothings ( 19 . 1 ,  19 . 2 ) of a fork element ( 15 ). 
     
     
         8 . The compressor as claimed in  claim 7 , characterized in that the fork element ( 15 ) forms an elongate opening ( 18 ) into which the step-up transmission wheel ( 3 . 1 ) engages and in which the toothings ( 19 . 1 ,  19 . 2 ) are also arranged. 
     
     
         9 . The compressor as claimed in  claim 7 , characterized in that pistons ( 6 . 1 - 6 . 6 ) are arranged on both sides of the fork element ( 15 ). 
     
     
         10 . The compressor as claimed in  claim 8 , characterized in that pistons ( 6 . 1 - 6 . 6 ) are arranged on both sides of the fork element ( 15 ).
