A hydraulic apparatus (200) for converting wave energy is disclosed. Apparatus (200) includes a pump (200) for pumping hydraulic fluid around a closed loop hydraulic circuit of the apparatus (200). An outlet check valve (215) and an inlet check valve (221) assist with regulating the direction of flow of the fluid around the circuit. Apparatus (200) also includes accumulators (2212, 214, 222, 223, 226), and pressure relief valves (224, 225). L'invention concerne un appareil hydraulique (200) destiné à convertir l'énergie de la houle. L'appareil (200) comprend une pompe (200) servant à pomper du fluide hydraulique dans un circuit hydraulique en boucle fermée de l'appareil (200). Un clapet anti-retour (215) de sortie et un clapet anti-retour (221) d'entrée contribuent à réguler la direction d'écoulement du fluide le long du circuit. L'appareil (200) comprend également des accumulateurs (2212, 214, 222, 223, 226) et des soupapes (224, 225) de décharge.
