Abstract
The disclosure relates to a volume flow supply, in particular for closed center LS systems, comprising a pressure supply device and a pressure balance as components of a supply system for supplying fluid of a load which can be hydraulically connected to the supply system. The pressure supply device provides a volume flow when required in order to supply the hydraulic load in that the pressure balance is made of a circulation pressure balance which discharges a possible surplus volume flow out of the supply flow. The volume flow supply also comprises a controller which reduces the surplus volume flow to a minimum by actuating the pressure supply device.
