Abstract

Martinetto idraulico autobloccante a doppio effetto, ad asta (2) e pistone (3) immobilizzato in un cilindro (4), caratterizzato del fatto che il suo pistone (3) è montato serrato in un cilindro esterno (4) e liberato nei suoi movimenti rispetto a questo cilindro (4) mediante una dilatazione di questo cilindro nei confronti del pistone, apportata dalla pressione di un fluido, il pistone essendo azionato da un fluido motore.L'asta (2) del martinetto comprende, secondo una variante, un dispositivo idromeccanico di azionamento in rotazione (31) nella sua estremità posteriore.Questa invenzione ha interesse per i costruttori ed i fabbricanti di materiale idromeccanico.
