Cleaning device, compressed-air system, vehicle and cleaning method

1. A cleaning device for selectively bombarding a surface with a first medium, the cleaning device comprising:

an accumulator valve module, comprising:

a high-pressure accumulator configured to store the first medium at a high-pressure accumulator pressure,

an impulse nozzle configured to bombard the surface with the first medium,

a changeover valve configured as a solenoid valve having a nozzle connector configured to connect to the impulse nozzle and a high-pressure accumulator connector configured to connect to the high-pressure accumulator, wherein the changeover valve is configured to:

connect, in a release position, the high-pressure accumulator and the impulse nozzle via the high-pressure accumulator connector and the nozzle connector,

interrupt, in a charge position, a flow path from the high-pressure accumulator to the impulse nozzle, and

switch between the release position and the charge position; and

a high-pressure accumulator holding valve connecting the high-pressure accumulator to the first medium source, the high-pressure accumulator holding valve being configured to block a flow of the first medium in a direction from the high-pressure accumulator to the first medium source.

2. The cleaning device as claimed in claim 1 , wherein the solenoid valve is a 2/2-way valve.

3. The cleaning device as claimed in claim 1 , wherein:

the changeover valve is configured to form, in the release position, a first connection between the high-pressure accumulator and the impulse nozzle, the first connection including the high-pressure accumulator connector, the nozzle connector, and a nozzle supply line.

4. The cleaning device as claimed in claim 1 , further comprising a second nozzle configured to bombard the surface with a second medium;

wherein the cleaning device is configured to bombard the surface with a media sequence of the first medium and the second medium,

wherein the first medium is a gaseous medium and the second medium is a liquid medium.

5. The cleaning device as claimed in claim 1 , wherein the solenoid valve includes a magnetic coil unit configured to switch the solenoid valve from the charge position to the release position.

6. The cleaning device as claimed in claim 1 , wherein the accumulator valve module further comprises a supply line check valve, the supply line check valve being configured to block a flow of the first medium in a direction from the high-pressure accumulator to a first medium supply line.

7. The cleaning device as claimed in claim 1 , wherein the high-pressure accumulator has a holding capacity between 2 ml and 10 ml.

8. A compressed-air system, comprising:

at least one cleaning device as claimed in claim 1 ,

wherein the first medium source is a medium source of the compressed-air system and, wherein the first medium source is, by way of a first medium supply line, configured to be connected to the at least one cleaning device.

9. The compressed-air system as claimed in claim 8 , further comprising:

a second medium source, wherein the second medium source is, by way of a second medium supply line, configured to be connected to the at least one cleaning device.

10. The compressed-air system as claimed in claim 8 , wherein the compressed-air system has a supply line check valve,

wherein the supply line check valve is disposed in the first medium supply line,

wherein the supply line check valve is configured to block a flow of the first medium in a direction opposite a conveying direction of the first medium source and/or is configured to maintain a supply pressure in a line connected to the high-pressure accumulator.

11. A vehicle having a compressed-air system as claimed in claim 8 .

12. The vehicle as claimed in claim 11 , wherein, in the compressed-air system, the first medium source is configured to supply an air suspension system of the vehicle.

13. The vehicle as claimed in claim 11 , wherein, in the compressed-air system, the second medium source is configured to supply a cleaning system of the vehicle.

14. The vehicle as claimed in claim 11 , wherein, in the compressed-air system, the first medium source has a compressor assembly and/or a compressed air accumulator.
