Beschreibung
Zusammenfassung:	An air spring apparatus has quick pressure release, and rapid air exhaust, capability by means of a relatively large diameter exhaust port in a larger, primary air spring which is controlled by the action of a smaller, secondary air spring. The secondary air spring is equipped with a check valve which controls the flow of air into the primary air spring. The rapid exhaust of the primary air spring is effected by triggering the removal of air pressure from the secondary air spring through a plurality of orifices in a centrally disposed guide tube which permits the collapse of the smaller air spring and the accompanying removal of a valve plate from a relatively large diameter exhaust port of the primary air spring. Once the exhaust port in the primary air spring has been opened, the air pressure in the primary air spring is immediately lowered, and the load on the larger air spring causes rapid expulsion of the volume of air in the primary air spring to permit its quick deflation and collapse to a predetermined minimum height.
