Abstract
An apparatus comprising: a series of units, each being capable of producing a volume flow; a first channel for supplying hydraulic fluid into the apparatus; a second channel for supplying hydraulic fluid from the apparatus; a first series of valves comprising at least one controlled valve for each unit; a third channel for supplying hydraulic fluid from the apparatus; and several controlled auxiliary valves, each being provided for one unit. The control circuit also comprises: at least one actuator for converting hydraulic energy to mechanical energy, wherein said actuator is at least connected to either the second channel or the third channel; and a control device configured to synchronize the operation of the valves of the first series of valves and said auxiliary valves with the operation of said units, and to control the actuator by means of pressure and volume flow. In the method, the operation of the first series of valves and said auxiliary valves is synchronized with the operation of said units, and controlling the pressure and the volume flow in a predetermined manner, for controlling one or more actuators by means of a control device.
