Abstract

Viene descritta una valvola a più vie, in particolare una valvola a 4/2 vie, la cui scatola è provvista di un foro assiale, realizzato a più gradini per la formazione di quattro elementi di contatto disposti in successione, il quale comprende due camere terminali nonché almeno due vani intermedi, disposti tra queste, in cui sbocca di volta in volta uno degli attacchi. Nel foro assiale è disposto un trascinatore a saracinesca che porta almeno due elementi di chiusura, il quale, da un lato, è condotto a tenuta stagna e, dall'altro lato, è sostenuto radialmente tramite nervature radiali nel foro assiale. Questo trascinatore presenta un canale longitudinale che, ad una estremità, è collegato tramite fori radiali con la prima camera e, all'altra estremità, è collegato, tramite la sua imboccatura prevista sul relativo lato frontale del trascinatore, con la seconda camera. Gli elementi di chiusura che cooperano, almeno parzialmente in modo elasticamente cedevole, con gli elementi di contatto, sono strutturati a forma di manicotto o di anello e presentano di volta in volta due superfici di tenute opposte, appoggiabili, a seconda della posizione di commutazione, all'uno o all'altro elemento di contatto della coppia di elementi di associata.
