Abstract

Un dispositivo (10) di intercettazione e movimentazione di fluido comprende un primo (12) ed un secondo blocco (11) fra loro affrontati con interposizione di una membrana (13) impermeabile elastica e flessibile. Nel primo blocco (12) è realizzata almeno una concavità (16) con bocca prossima alla membrana (13) e in cui sbocca in modo sostanzialmente assiale un condotto (17) di adduzione di fluido di comando. Nel secondo blocco (11) sono realizzati condotti (14, 15) di circolazione del fluido intercettato sboccanti nella faccia di contatto con la membrana (13), in corrispondenza della concavità (16) nel primo blocco (12).
