Abstract (en)

The arrangement has at least two pumps (2) for delivering fluid into a pressure reservoir (10) and an intermediate reservoir (3) for damping dynamic pressure components, whereby each pump is connected via a separate pump line (4) to the intermediate reservoir. Three pumps and lines can be used and the lines have non-return valves (9) at the ends connected to the intermediate reservoir. Independent claims are also included for the following: a large diesel engine with a pump device.
