(EN) AIR SUSPENSION DEVICE
(FR) DISPOSITIF DE SUSPENSION PNEUMATIQUE
(JA) エアサスペンション装置
Abstract
(EN)
This air suspension device is provided with: a compressor for compressing air; a tank for storing air; a tank-side intake pipeline for supplying compressed air in the tank to an intake side of the compressor; a tank pipeline connecting a discharge side of the compressor and the tank; an air suspension connected to to the discharge side of the compressor by way of an air dryer; an intake solenoid valve provided in the tank-side intake pipeline; a return solenoid valve provided in the tank pipeline; and a vent pipeline which is provided branching from between the discharge side of the compressor and the air dryer, and which is connected to the atmosphere by opening the venting solenoid valve.
(FR)
L'invention concerne un dispositif de suspension pneumatique comprenant : un compresseur pour comprimer de l'air; un réservoir pour stocker de l'air; une conduite d'admission côté réservoir pour fournir de l'air comprimé dans le réservoir à un côté d'admission du compresseur; une conduite de réservoir reliant un côté refoulement du compresseur et le réservoir; une suspension pneumatique reliée au côté refoulement du compresseur au moyen d'un dessiccateur d'air; une électrovanne d'admission disposée dans la conduite d'admission côté réservoir; une électrovanne de retour disposée dans la conduite de réservoir; et une conduite de mise à l'air libre qui se ramifie depuis un emplacement entre le côté refoulement du compresseur et le dessiccateur d'air et qui est reliée à l'atmosphère par ouverture de l'électrovanne de mise à l'air libre.
(JA)
空気を圧縮するコンプレッサと、空気を貯留するタンクと、タンク内の圧縮空気をコンプレッサの吸気側に供給するタンク側吸込管路と、コンプレッサの吐出側とタンクとを繋ぐタンク用管路と、コンプレッサの吐出側にエアドライヤを介して接続されるエアサスペンションと、タンク側吸込管路に設けられる吸気電磁弁と、タンク用管路に設けられる戻し電磁弁と、コンプレッサの吐出側とエアドライヤとの間から分岐して設けられ、排気電磁弁を開弁することにより大気に接続される排気管路とを備えている。
