Abstract

L'invenzione concerne una valvola a cassetto, costituita da un corpo con un foro di guida e almeno da un'entrata del fluido sotto pressione come pure da più condotti del fluido sotto pressione, sporgenti lateralmente attraverso il corpo nel foro di guida, da un elemento valvolare, collegato con un mezzo di azionamento, in particolare un pistone, assialmente spostabile nel foro di guide. Per potere rinunciare nel caso di una valvola a cassetto di questo genere ad elementi di tenuta separati e assicurare una chiusura a tenuto lungo un lasso di tempo prolungato nel funzionamento, secondo l'invenzione viene proposto che almeno l'elemento valvolare (3) è costituito da un materiale deformabile elasticamente sotto l'alimentazione con pressione ed è dotato di un foro cieco (5), il quale si estende in direzione assiale ed è aperto verso il lato opposto al mezzo di azionamento (4), e che l'entrata (P) del fluido sotto pressione sporge nel foro di guida (6) in modo che in ogni posizione dell'elemento valvolare (3) esiste un collegamento ad accoppiamento di fluido sotto pressione verso il foro cieco (5).
