Membrane Air Springs (BiAir) by Bilz Vibration Technology AG

The Air Spring Insulator BiAir® consists of a cast steel or aluminum housing, within which the air space is contained by thin-walled flexible and pressure-resistant rolling membrane. A piston sits on top of the membrane and is pressed into the air space. This design allows a highly-effective isolation of vibration. In order to simultaneously achieve a high degree of damping, the air space is divided into two chambers connected with an air tube. (load/damping volume) A choke valve can be used to adjust from outside the cross-section of air flowing into the connecting tube from outside according to the degree of damping required. The friction on the flow of air caused by the choke valve can create a damping effect of up to 20%. Damage to the rolling membrane caused by overpressure is prevented by additional safety valves.
