munirabbasi Posted December 21, 2018 Share Posted December 21, 2018 Hello Hydraulic Expertise In normal brake Pressure line near to Normal brake selector valve (100CU IN Accumulator),one way restrictor is installed but in Emergency brake pressure line the restrictor is not installed (50 CU IN Accumulator) both hydraulic lines pressure are same (3000 PSI) what is the reason behind it?

Munir Abbasi Normal brake accumulator has a restrictor because of anti-skid system. Emergency does not have anti-skid Anti-skid plus normal demand of brake application can deplete the accumulator rapidly. The restrictor ensures the utility system pressure goes to the brakes instead of filling the accumulator. The restrictor is free flow OUT of accumulator but restricted flow IN to accumulator. Acts like a priority valve for normal brakes. Quote Link to comment Share on other sites More sharing options...
