Pressure regulation process for liquid fuel injection device, involving regulating pressure in store cavity by controllable pressure holding valve

摘要

The pressure regulation process involves regulating the pressure in the pressure store (3) by means of a controllable pressure holding valve (8). The amount of fuel flowing into the high pressure pump (4) is regulated depending on the throughput of the pressure holding valve, so that if the throughput through the outflow line (9) rises, the inflow to the high pressure pump is reduced.
