Zusammenfassung:The valve actuator arrangement of an engine comprises a cam-driven piston device (3), which divides a pressurizing chamber (4) into at least two sections (4a, 4b, 4c, 4d) and pressurizes hydraulic fluid in the chamber (4) for opening gas exchange valves (1, 1'). The piston device (3) is used for driving at least one additional valve (9, 10) other than a gas exchange valve (1, 1').
