Abstract

The water conduit system (1) is connected to at least two water cylinders (3, 4), each of which uses its piston (11, 12) to deliver high-pressure water into the system. The pistons are connected to a drive unit (19, 20) for moving the pistons in and out of the cylinders in order to maintain the desired water pressure. The drive unit comprises a hydraulic device with a drive cylinder for each water cylinder.
