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.

First claim

The invention claimed is:

1. A compressor for discharging a tire sealant from a container into a tire, said compressor comprising a motor ( 1 ) that drives a step-up transmission wheel ( 3 ) which in turn drives an output wheel ( 4 ) for moving at least one piston ( 6 - 6 . 6 ) between a compression stroke and an intake stroke in a compression chamber ( 7 ), sucking in air during the intake stroke and forcing air and tire sealant from the container during the compression stroke, the step-up transmission wheel ( 3 ) being two entirely toothed wheels ( 11 , 12 ) lying on each other, a first ( 12 ) of the two entirely toothed wheels having a smaller diameter than a second ( 11 ) of the two entirely toothed wheels, and the output wheel ( 4 ) being two partially toothed wheels ( 4 . 1 , 4 . 2 ) lying on each other, a first ( 4 . 2 ) of the partially toothed wheels having a larger diameter than a second ( 4 . 1 ) of the partially toothed wheels, wherein the first entirely toothed wheel ( 12 ) is configured to interact with the teeth of the first partially toothed wheel ( 4 . 2 ) during the intake stroke and the second entirely toothed wheel ( 11 ) is configured to interact with the teeth of the second partially toothed wheel ( 4 . 1 ) during the compression stroke.

2. The compressor as claimed in claim 1 , wherein the step-up transmission wheel ( 3 ) is connected eccentrically to the 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 , wherein the toothing ( 14 . 1 ) of the second ( 4 . 1 ) of the partially toothed wheels extends about one arc distance and the toothing ( 14 . 2 ) of the first ( 4 . 2 ) of the partially toothed wheels extends about another arc distance.

4. The compressor as claimed in claim 3 , wherein the number of degrees is in each case 180°.
