Can someone explain me the function of following armature in a kitchen?
The valve is probably for the dish washer, but what is the purpose
for the metal thing below? It does not seem modifiable and has small
slides near the front cap.
The armature is at a height of about 1.2m in the middle of the kitchen wall.
At a height of about 30cm there are different connections
(water for dish washer and regular kitchen water / wastewater connections).
To do this right, you'll likely have to install a whole drain system for the washer. You'll install a new vent (according to local codes), and a new drain line that attaches to the existing drainage system (in a code compliant way). Then you'll install a standpipe with a trap, that the washer can discharge to.
I can only think of three options here...
The first (less optimal) option, is to raise the discharge up and allow it to flow down to the drain connection. In this scenario, you'll want to have the discharge tube go up to an air admittance device (AAV) or air gap. From there it should flow downhill (1/4" per foot), until it reaches the garburator connection.
The other option, is to discharge the dishwasher to its own drain. Install a properly vented standpipe near the dishwasher, and connect the discharge tubing to that (follow local plumbing codes).
The last option is to run a drain line under the floor, and attach to the sink drain below the floor. Install a trap near the dishwasher, and run a proper drain that tees into the sink drain (follow local plumbing codes).

I highly doubt this is a valve for the dishwasher. Since this is above the countertop (which I'm assuming since there's tile on the wall), it may be a pot filler with the end capped off.
