Abstract

Limitatore di portata di fluido costituito da un corpo (1) comportante un alesaggio di cui una estremità (2) è chiusa e l'altra (4) aperta è collegata ad un apparecchio idraulico, all'interno del quale è montato un cassetto tubolare (5) guidato in traslazione nell'alesaggio e mobile sotto l'influenza di una differenza di pressione che agisce contro sollecitazioni esercitate dal fluido, il cassetto (5) comporta nella sua parte centrale un incavo anulare (7) nel quale sboccano due serie di orifici (8, 9) praticati nel corpo (1) sfalsati assialmente e presenta due scompartimenti (10, 11) separati da una spalla centrale (12) in modo che quello (10) situato dal lato chiuso (2) del corpo (1) comunica con l'incavo anulare (7) tramite almeno un alesaggio (13) e contenente un otturatore (14) sottoposto all'azione di mezzi elastici che lo applicano contro la spalla nel senso del flusso del fluido regolato, dei mezzi elastici (17) esercitando sul cassetto una forza in direzione dell'estremità chiusa del corpo.
