The invention relates to a method for controlling an electromagnetic pressure control valve for pressure regulation in a high-pressure accumulator of a fuel injection system of an internal combustion engine, in particular in a common-rail injection system....

A valve arrangement (28) for use in limiting the pressure of fuel within an accumulator volume of an accumulator fuel system to a predetermined threshold level, the valve arrangement (28) comprising: a valve outlet (64, 66) for communication with a low pre...

A pressure-reduction valve (11) that returns fuel in a common rail (1) to a low-pressure system (9) is configured so that that an actuator (28) changes a valve-opening pressure of the valve device (21) into a target common rail pressure (PC0). Thus, when t...

The injection system (1) includes a storage volume (6) of pressurized fuel supplied by a high-pressure pump (7) along a delivery pipe (8); and a control unit (16) for defining the required fuel pressure of the storage volume (6) as a function of the operat...
