| 摘要 |
The present invention relates to an arrangement for controlling at least one engine valve (25) of a combustion engine. The arrangement incorporates a hydraulic circuit with a pump (1), a control valve (2) which is designed to control a flow of medium in the circuit, and a power device (3) which is designed to move the engine valve (25) between open and closed positions. The pump (1) is designed to circulate a flow of medium continuously in at least part of the circuit during an operating state of the combustion engine, and the control valve (2) is designed to direct as necessary the flow of medium circulated by the pump (1) to the power device (3) so that the latter moves the motor valve (25) in a desired direction.
