Abstract
The invention relates to a fluid flow arrangement (1, 15) with an adjustable fluid pumping device (2) and a fluid working machine (12). The fluid working machine (12) is connected to the fluid pumping device (2) and a re-circulating loop is provided for the fluid working machine (12). The re-circulating loop is fluidly connecting a first fluid port (A) and a second fluid port (B) of the fluid working machine (12), where the first (A) and the second fluid port (B) are at times at a different pressure level. The re-circulating loop comprises a controllable fluid throttling device (21, 22), and a switchable fluid conduit device (23, 24), so that a defined decelerating force can be generated for the fluid working machine (12).
