Device for delivering a medium

Abstract

In a device for delivering a medium, especially tire sealant, which is to be delivered by means of a compressor (P) from a container to a tire, wherein the compressor can be connected by a pipeline ( 9 ) to the tire and a connection ( 10 ) to the container emerges into this pipeline ( 9 ), the pipeline ( 9 ) has a constriction ( 27 ) upstream from the tire.

1 . A device for delivering a medium by a compressor from a container to a tire, wherein the compressor can be connected by a pipeline to the tire and a connection to the container emerges into this pipeline,
 wherein the pipeline has a constriction upstream from the tire.   
     
     
         2 . The device according to  claim 1 , wherein the constriction includes a Venturi tube. 
     
     
         3 . The device according to  claim 1 , wherein the connection to the container emerges into the pipeline upstream from the constriction and extends there axially in trunk-like fashion in a direction of the constriction. 
     
     
         4 . A device for delivering a medium by means a compressor from a container to a tire, wherein a compression chamber of the compressor can be connected by a pipeline to the tire and a connection to the container emerges into this pipeline, wherein the pipeline and connection are combined into a valve unit connected in bayonet fashion to the compression chamber. 
     
     
         5 . The device according to  claim 4 , wherein the compression chamber has a top collar molded on the compression chamber, the top collar having a locking device and with hook-like moldings of the valve unit reaching underneath the locking device. 
     
     
         6 . The device according to  claim 4 , wherein a connection opening between the valve unit and the compression chamber is occupied by a seal. 
     
     
         7 . The device according to  claim 6 , wherein the seal is a flexible, discus-shaped disk. 
     
     
         8 . The device according to  claim 6 , wherein the seal is configured as a shuttlecock. 
     
     
         9 . A compressor for delivering a medium from a container to a tire, wherein a motor of the compressor is eccentrically connected via a power takeoff gear to a piston rod, moving a piston in a compression chamber, wherein the power takeoff gear has a transmission gear upstream from the power takeoff gear. 
     
     
         10 . The compressor according to  claim 9 , wherein the power takeoff gear includes two half gears each with a toothing, wherein the toothing of one of the half gears extends across one radian measure and the toothing of another of the half gears extends across another radian measure. 
     
     
         11 . The compressor according to  claim 10 , wherein the radian measure is 180°. 
     
     
         12 . The compressor according to  claim 9 , wherein the transmission gear includes two gears situated one on top of each other, interacting in alternation with one or the other half gear of the power takeoff gear. 
     
     
         13 . The compressor according to  claim 12 , wherein one of the gears of the transmission gear has a larger diameter than another one of the gears of the transmission gear. 
     
     
         14 . The device according to  claim 1 , wherein the medium is a tire sealant. 
     
     
         15 . The device according to  claim 2 , wherein the connection to the container emerges into the pipeline upstream from the constriction and extends there axially in trunk-like fashion in a direction of the constriction. 
     
     
         16 . The device according to  claim 4 , wherein the medium is a tire sealant. 
     
     
         17 . The device according to  claim 4 , wherein a connection opening between the valve unit and the compression chamber is occupied by a seal. 
     
     
         18 . The compressor according to  claim 9 , wherein the medium is a tire sealant. 
     
     
         19 . The compressor according to  claim 11 , wherein the transmission gear includes two gears situated one on top of each other, interacting in alternation with one or the other half gear of the power takeoff gear.
