Abstract
Il blocco di distribuzione per freno idraulico è costituito da un blocco (1) vero e proprio, dotato di due condotti (2, 3) ciascuno dei quali è previsto per fungere indifferentemente da condotto d'entrata o uscita di fluido pressurizzato che proviene dal o va ai motori di frenatura, ciascuno dei quali è unito a due valvole unidirezionali (4, 5 e 6, 7) rispettivamente delle quali le valvole (5 e 7) fanno passare il fluido che proviene dal condotto corrispondente (2, 3) e lo inviano ad una valvola di pressione (10), che viene pilotata tramite la valvola (11), da cui esce attraverso il condotto (12) per dirigere, dopo essere passato attraverso un raffreddatore esterno (13), mediante il condotto (14) che comunica con la valvola (15), la pressione d'alimentazione che comunica alla sua uscita con un condotto (8) unente le valvole unidirezionali (4, 6) che non devono far passare il fluido che giunge dai condotti (2, 3) rispettivamente.
