Abstract (en)
[origin: WO2006019341A1] The present invention relates to an apparatus for generating and maintaining a desired pressure/flow in a water conduit system (1) with a number of take-off points for the connection of closable and openable high pressure water nozzles for use in high pressure water spraying, e.g. cleaning, the water conduit system (1) being connected to at least two water cylinders (3, 4) each with its piston (11, 12) for the infeed of high pressure water into the water conduit system (1), and the pistons (11, 12) are connected to a drive unit (19, 20) for driving the pistons (11, 12) in the cylinders (3, 4) for generating and maintaining a predetermined water pressure in the the water conduit system (1).
