Abstract
Un attuatore idraulico, particolarmente per servosterzi di autoveicoli, comprende un corpo tubolare cilindrico dotato di elementi di chiusura alle rispettive estremità, ed alloggiante un pistone portante uno stelo di comando che attraversa scorrevolmente a tenuta gli elementi di chiusura. Il corpo tubolare presenta un'anima tubolare in forma di profilato estruso, avente le rispettive estremità ermeticamente impegnate dagli elementi di chiusura, e portante sedi di attacco per l'impegno a tenuta di elementi di raccordo idraulico, confluenti in rispettive camere di pressurizzazione delimitate, all'interno del corpo tubolare cilindrico, dal pistone. Il profilato tubolare risulta rivestito da un mantello pressofuso, portante appendici di attacco per il fissaggio dell'attuatore ad una struttura di supporto.
