Function of headlamp cleaning system
telescopic nozzles

n

After the HCS pump (M5/2) has started to operate, pressure builds
up in the washing water line for approx. 1 second. Driven by the
water pressure, the nozzles first move telescopically into the cleaning
position. Then as a result of a further pressure rise, a valve at each
telescopic nozzle opens and an exactly metered quantity of washing
water is sprayed onto the headlamp lenses.

Swirl chambers are provided at the tips of the telescoping sections
and these ensure controlled propagation of the water jet, even when
traveling fast. After the cleaning process, the telescoping sections
are retracted back into the starting position with the aid of return
springs.
