Abstract

Valvola dosatrice in cui un involucro esterno (48) delimita una prima (100a) ed una seconda camera (100b) comunicanti tra di loro attraverso un foro (105) e comunicanti con l'esterno dell'involucro attraverso un rispettivo condotto di alimentazione fluido (107) ed un rispettivo condotto di ricircolo (108). La prima camera comunica inoltre con l'esterno con un condotto erogatore (98) ed alloggia un otturatore (111) che è assialmente mobile all'interno della camera stessa tra una prima posizione in cui una prima porzione (130) dell'otturatore chiude il foro (105) ed una seconda posizione in cui una seconda porzione (135) dell'otturatore chiude il condotto erogatore (89). Per qualsiasi posizione intermedia tra la prima e la seconda posizione, la somma delle aree delle luci comprese tra il condotto (98) e la seconda porzione (135) e rispettivamente il foro (105) e la prima porzione (130) è sensibilmente costante. Per tale motivo, per qualsiasi posizione dell'otturatore, la valvola dosatrice presenta una sezione totale di passaggio fluido costante.[Fig. 4].
