摘要： The invention relates to an arrangement (1) for operating a gas exchange valve (2) of a piston engine. The arrangement comprises a hydraulic actuator (3) for moving the gas exchange valve (2) toward an open position by pressure of hydraulic fluid acting in a pressure chamber (7) of the hydraulic actuator (3), a hydraulic fluid source, (11) and a drain line(15). The arrangement (1) further comprises a proportional control valve (17) having a valve member (19) and an electrical actuator (18) arranged to directly move the valve member(19). The valve member(19) is movable to a first main position, in which the control valve (17) is arranged to connect the hydraulic fluid source (11) to the pressure chamber (7), and a second main position, in which the control valve (17) is arranged to connect the pressure chamber (7) to the drain line (15).

摘要： The inventive control arrangement comprises a feedback controller, in an iterative learning controller (1 ), and a delay controller (16). The feedback controller drives EHVA system. The EHVA systems means in this context the system needed to drive one valve or the system driving several valves. For simplicity, it is easier and more understandable to think about the driving of one valve. It is clear that the drive of one valve is expandable to the system driving several valves

摘要： An apparatus comprising: a series of units, each being capable of producing a volume flow; a first channel (T) for supplying hydraulic fluid into the apparatus; a second channel (A) for supplying hydraulic fluid from the apparatus; a first series of valves comprising at least one controlled valve (12, 34) for each unit; a third channel (B) for supplying hydraulic fluid from the apparatus; and several controlled auxiliary valves (18, 30), each being provided for one unit. The control circuit also comprises: at least one actuator (13, 28, 29) for converting hydraulic energy to mechanical energy, wherein said actuator is at least connected to either the second channel (A) or the third channel (B); and a control device (25) 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 (p1, Q1). 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.
