Headlamp Washer Spray Nozzle: Description and Operation

Arrangement
The telescopic nozzles are in the center, below the head lamps.

Design
The telescopic nozzle is a hydraulically operated telescope with an integrated return spring. It is not connected to the electricity.

Task
Cleaning the headlamp lenses.

Function
After the SRA pump (M5/2) has started, pressure builds up for approx. 1 second in the washing water pipe. Driven by the water pressure, the nozzles move telescope-like into the cleaning position.

Then another increase in pressure at each telescopic nozzle opens a valve and an exactly measured amount of water is sprayed onto the headlamp lenses. After use, the nozzle; are returned to their starting position with the aid of return springs.
