Hydraulic switching for vehicle multicircuit brakes - has central reservoir incorporated in main supply line in front of branches to individual brake circuits

摘要

The hydraulic switch for a multicircuit braking system for a vehicle such as a heavy transporter having a main supply pipe (1,2) branching into circuits each with a pressure reservoir (5.1, 5.2, 5.3). A central reservoir is interposed (4) in the delivery pipe (1,2) before the branching arrangement, and each of the branch circuits has a switching valve (10,20) which in the event of a pressure drop throttles or interrupts the fluid connection with the main pipe. ADVANTAGE - Braking system which remains functional in the event of the failure of one of the circuits.
