Title: CHECK VALVE FOR WAVE ENERGY HARVESTING DEVICE
Abstract:
Check valve for a wave energy harvesting device, which allows the passage of air in a single direction and comprises a bonnet (2) articulated to a support (7), the bonnet (2) being configured to close against a valve seat (3) blocking the passage of air, and said bonnet (2) being pivotable with respect to the support (7) about a geometric pivot axis. The valve comprises at least one articulation (9) attaching the bonnet (2) to the support (7), where each articulation (9) comprises elastic and/or magnetic attachment means (10) which allow the geometric pivot axis to swing with respect to the support (7) during opening and closing of the bonnet (2), the geometric pivot axis of the bonnet (2) being arranged coplanar with respect to the valve seat (3) in a closed position of the check valve (1).
