Abstract

Un dispositivo a cilindro - pistone con un gruppo costruttivo a pistone (7) alternativamente mobile coopera, in almeno una delle posizioni finali, con uno smorzamento (9) di posizione finale, questo presentando un disco di battuta non metallico (11) assorbente l'energia cinetica del gruppo costruttivo a pistone (7) e una guarnizione di smorzamento (15) disposta scorrevolmente in uno spazio interno (12) del disco di battuta (11) su un pistone smorzante (14) del gruppo costruttivo a pistone.Per migliorare l'effetto smorzante accanto allo smorzamento d'urto con uno smorzamento a compressione, viene proposto che sia prevista una bussola ad inserto (10) che è chiusa a tenuta e fissata assialmente nel tubo cilindrico (2) e porta, rivolta al gruppo costruttivo di pistone (7), su una sporgenza a mozzo (22) il disco di battuta elastica (11), e che nella bussola ad inserto (10) è formato uno spazio interno (10b), dal quale è asportabile, attraverso canali di disaerazione (20), il fluido compresso con smorzamento.
