Servohydraulic device i.e. internal pressure pulsating device, for injection line of internal combustion engine, has adjusting device adjusting time-variant fluid pressure and/or adding fluid pressure to another time-variant fluid pressure
The device (1) has a time-variant fluid pressure producing device (2) and a time-variant fluid pressure adding device (3), which have pistons (4, 6) that are movably guided in respective cylinders (5, 7). The devices (2, 3) produce time-variant fluid pressure (P1, P2) in respective pressure chambers (V1, V2). The adding device has an adjusting device for adjusting or regulating the time-variant fluid pressure (P1) and/or adding the time-variant fluid pressure (P1) to the time-variant fluid pressure (P2), where the pressure (P2) is larger than the pressure (P1) at a time period. An independent claim is also included for a method for producing a time-variant fluid pressure.
