Title
(EN) DAMPER WITH SINGLE EXTERNAL CONTROL VALVE
(FR) AMORTISSEUR À SOUPAPE DE COMMANDE EXTERNE UNIQUE
Abstract
(EN)
A damper with inner and outer tubes and a piston slidably disposed within the inner tube to define first and second working chambers. A collector chamber is positioned outside the outer tube. An external control valve is positioned in fluid communication with the collector chamber. An intake valve assembly, mounted to one end of the inner tube, includes an intake valve body, intake passages, and intake valve. The intake valve body abuts the outer tube to define an accumulation chamber positioned between the intake valve assembly and a closed end of the outer tube. The accumulation chamber is arranged in fluid communication with the collector chamber. The intake valve body forms a fluid-tight partition between the accumulation chamber and a fluid transport chamber is positioned between the inner and outer tubes. The intake valve controls fluid flow between the accumulation chamber and the second working chamber through the intake passages.

Un amortisseur comprend des tubes interieur et exterieur et un piston disposé de façon coulissante à l'intérieur du tube interne pour définir des première et seconde chambres de travail. Une chambre collectrice est positionnée sous le tube extérieur Une soupape de commande exterieure est positionnée en communication fluidique avec la chambre collectrice. Un ensemble soupape d'admission, monté sur une extrémité du tube intérieur, comprend un corps de soupape d'admission, des passages d'admission et une soupape d'admission. Le corps de soupape d'admission vient en butée contre le tube extérieur pour définir une chambre d'accumulation positionnée entre l'ensemble soupape d'admission et une extrémité fermée du tube extérieur. La chambre d'accumulation est disposée en communication fluidique avec la chambre collectrice. Le corps de soupape d'admission formaant une cloison étanche aux fluides entre la chambre d'accumulation et une chambre de transport de fluide est positionnée entre les tubes interieur et exterieur. La soupape d'admission commande l'écoulement de fluide entre la chambre intermédiaire et la seconde chambre de travail.
