Abstract

Si tratta di un azionatore lineare, il quale è dotato di un corpo (1), in cui è accolta una parte di azionamento (2) alternativamente mobile in modo assiale fra posizioni terminali. Al corpo è contrapposta su almeno un lato assiale una parete (4, 5) collegata con il corpo (1). Sono previsti mezzi per ridurre l'urto nelle posizioni terminali della parte di azionamento (2), i quali presentano un labbro anulare (12). Esso è disposto o sulla parte di azionamento (2) o sulla parete contrapposta (4, 5) e delimita uno spazio di smorzamento (15), il quale è aperto in corrispondenza del lato di urto (17). Se la parte di azionamento (2) si avvicina a una posizione terminale, allora lo spazio di smorzamento viene chiuso e ridotto nel volume. Così il fluido racchiuso fuoriesce attraverso un'apertura di scarico (18) in modo che si regoli un movimento di corsa frenato. Con un basso onere costruttivo si ottiene così uno smorzamento fluidodinamico estremamente efficace nelle posizioni terminali.
