Pressure limiter valve
Figure 8
158450
It is a safety valve mounted on the hydraulic accumulator which prevents the pressure of the fuel in the rail from exceeding the
threshold 2400 bar.
It consists of a shutter and a spring, calibrated so that when the pressure in the rail reaches too high a value, the valve regulates
it by releasing part of the fuel to the tank.
Furthermore, in case of failure of the injection pressure control system, it allows the engine to function with limited performance.
