Abstract

In a device for delivering a medium, especially tire sealant, which is to be delivered by means of 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, the pipeline has a constriction upstream from the tire.

First claim

The invention claimed is:

1. A compressor for delivering a medium from a container to a tire, the compressor comprising:
a motor;
a power takeoff gear including first and second half takeoff gears each with a toothing, the toothing of the first half takeoff gear extending across a first radian measure and the toothing of the second half takeoff gear extending across a second radian measure;
a piston rod in a compression chamber; and
a transmission gear including first and second transmission gears situated one on top of each other, the first transmission gear positioned to interact in alternation with the first half power takeoff gear and the second transmission gear positioned to interact in alternation with the second half power takeoff gear,
wherein the motor is eccentrically connected via the power takeoff gear to the piston rod and is configured to move the piston in the compression chamber by rotating the power takeoff gear and the transmission gear, and
wherein the transmission gear is upstream from the power takeoff gear.

2. The compressor according to claim 1 , wherein the first radian measure is 180° .

3. The compressor according to claim 1 , wherein the first transmission gear has a larger diameter than the second transmission gear.

4. The compressor according to claim 1 , wherein the medium is a tire sealant.

5. A device for delivering a medium to a tire, comprising:
a motor;
a valve unit having a medium connection in fluid communication with a medium supply, the valve unit also having a pipeline in fluid communication with the medium connection and configured for engagement with the tire;
a compressor having a compression chamber operatively connected to the valve unit, the compressor also having a piston movably mounted within the compression chamber for movement according to a compression mode of the compressor and for movement according to a suction mode of the compressor;
a power takeoff gear connected between the motor and the compressor for movement of the piston according to the compression mode and according to the suction mode, wherein the power takeoff gear transfers greater force from the motor to the compressor during the compression mode than during the suction mode,
wherein the power takeoff gear includes first and second half power takeoff gears each with a toothing, wherein the toothing of the first half power takeoff gears extends across one radian measure and the toothing of the second half power takeoff gear extends across another radian measure; and
a transmission gear that includes first and second transmission gears situated one on top of each other, the first transmission gear interacting in alternation with the first half power takeoff gear, the second transmission gear interacting in alternation with the second half power takeoff gear,
wherein movement of the piston during the suction mode moves the medium from the medium supply through the medium connection to the pipeline, and
wherein movement of the piston during the compression mode moves the medium from the pipeline to the tire.

6. The device according to claim 5 , wherein the pipeline includes a constriction configured to increase the flow of the medium downstream of the construction during the compression mode.

7. The device according to claim 6 , wherein the medium connection extends into the pipeline in the direction of the constriction for delivery of the medium upstream of the constriction.

8. The device according to claim 5 , wherein the medium is a tire sealant.

9. The device of claim 5 , wherein a connection opening between the valve unit and the compression chamber is occupied by a seal.

10. The device of claim 9 , wherein the seal is a flexible disk.

11. The device according to claim 9 , wherein the seal is configured as a shuttlecock.
