Abstract

Ammortizzatore regolabile per autoveicoli con un cilindro contenente un liquido ammortizzatore, un'asta di pistone, che penetra in esso ermeticamente ed è disposta scorrevole assialmente, e con un pistone ammortizzatore che è fissato ad essa e suddivide il cilindro in due spazi di lavoro, laddove la valvola ammortizzatrice, dotata di un corpo valvolare movibile assialmente e di una sede valvolare, comanda la sezione trasversale attiva di un canale ammortizzatore. Il corpo valvolare a tale scopo, partendo dalla sua superficie frontale sollecitata a pressione presenta almeno un foro di strozzatura costante, estendentesi verso il lato posteriore contrapposto, ed un foro di strozzatura, che si estende dal lato posteriore in direzione di deflusso del canale ammortizzatore viene comandato da un elemento di. precomando scorrevole continuamente assialmente, laddove l'elemento di precomando
