Abstract

L'invention concerne un amortisseur coaxial (1) pour un système hydraulique, amortisseur dans lequel un insert (3) est inséré dans un boîtier (2). Un premier raccord hydraulique (21) est formé sur le boîtier (2), un deuxième raccord hydraulique (31) est formé sur l'insert (3). Une structure de guidage d'écoulement (32), à travers laquelle un milieu hydraulique peut être guidé dans une chambre d'amortissement (4) de l'amortisseur coaxial (1), est formée sur l'insert (3).The invention relates to a coaxial damper (1) for a hydraulic system, in which an insert (3) is inserted in a housing (2). A first hydraulic connection (21) is formed on the housing (2), a second hydraulic connection (31) is formed on the insert (3). A flow guide structure (32), through which a hydraulic medium can be guided into a damping chamber (4) of the coaxial damper (1), is formed on the insert (3).
