Pressure accumulator

The pressure accumulator allows the vehicle

level to be raised more rapidly with minimal

noise as the pressure accumulator is only

ﬁlled while the vehicle is in driving operation

and the compressor noise is less noticeable

(see air supply strategy).

Provided that there is sufﬁcient pressure in

the pressure accumulator, vehicle level

raising can be performed without the

compressor.

Sufﬁcient pressure means that before the

vehicle is raised there must be a pressure

difference of at least 3 bar between the

pressure accumulator and the air springs.

The pressure accumulator is made of

aluminium and has a storage volume of

approx. 6.5 l. The maximum operating

pressure is approx. 16 bar.

Air supply strategy

At driving speeds of < 36 km/h air supply is

effected primarily by the pressure

accumulator (provided sufﬁcient pressure is

available).

The pressure accumulator is only ﬁlled when

driving at speeds of 36 km/h and above.

At a driving speed of > 36 km/h the air supply

is primarily from the compressor.

This supply strategy ensures virtually

noiseless system operation and reduces the

current consumption.
