A suspension damper includes a housing bounding a main chamber. A piston rod is slideably disposed within the main chamber of the housing. A main piston is mounted on the first end of the piston rod within the main chamber of the housing so as to slideably engage against the housing in sealed engagement, the main piston having a first side and an opposing second side with a compression port extending therebetween. A secondary piston is also disposed within the main chamber and has a compression port extending therethrough. A control valve assembly is disposed within the main chamber and bounds a sealed valve compartment. The control valve assembly is movable between a first position wherein the valve compartment is compressed to a first volume and a second position wherein the valve compartment is expanded to an enlarged second volume, the control valve assembly being movable under pressure so as to provide variable compression damping properties.
L'invention concerne un amortisseur de suspension comprenant un amortisseur de suspension comprenant un logement relié à une chambre principale. Une tige de piston est placée coulissante dans la chambre principale du logement. Un piston principal est monté sur la première extrémité de la tige de piston se trouvant dans la chambre principale de logement de manière à se coupler coulissant contre le logement de manière à former un contact étanche, le piston principal possédant un premier côté et un second côté opposé avec un orifice de compression s'étendant entre ceux-ci. Le piston secondaire est également placé dans la chambre principale et comporte un orifice de compression s'étendant à travers celle-ci. L'ensemble soupape de commande est placé dans la chambre principale et relie un compartiment de soupape étanche. L'ensemble soupape de commande peut être déplacé entre une première position dans laquelle le compartiment de soupape est comprimé à un premier volume, et une seconde position dans laquelle le compartiment de soupape est étendu à un second volume élargi, cet ensemble soupape de commande pouvant être déplacé sous pression de manière à offrir des propriétés d'amortissement à compression variable.
