Abstract

The present invention relates to a wave power device for extracting energy from water waves. The waver power device comprise a reference structure and effectors moving relative to the reference structure. The effectors are connected to two hydraulic rams, symmetrically positioned around each effector. The hydraulic rams have an effective hydraulic area which is stepwise increased as the length of the hydraulic rams are compressed and stepwise increased as the length of the hydraulic rams are increased.
