Abstract

Si intende realizzare un sistema idraulico con un corpo di strozzatura, di semplice esecuzione, altamente sollecitabile ed assumente sicuramente la sua posizione di montaggio.Il sistema idraulico possiede un generatore di pressione convogliante a impulsi, specialmente una pompa (13) a pistone, che pompa fluido sotto alta pressione in una camera di ammortizzatore (12) di una cassa (11). La camera (12) di ammortizzatore è collegata con un foro (15) che almeno approssimativamente è intersecato perpendicolarmente da un secondo foro (14) della cassa. Nel foro(14) della cassa è alloggiato un corpo di strozzatura (18), che è chiuso a tenuta perifericamente, è eseguito come manicotto e scavalca la zona di attraversamento del foro. In tal caso il foro di strozzatura (22), che attraversa la parete (23) del corpo di strozzatura (18), è situato nella sezione trasversale del foro di collegamento (15).L'esecuzione precedentemente descritta è impiegabile vantaggiosamente in sistemi idraulici, in cui fluido in pressione viene convogliato a impulsi con alte pressioni.
