A pressure-regulating buoyant hydrodynamic pump is disclosed that floats adjacent to a surface of a body of water over which waves tend to pass. In response to wave-induced movements of the device, water is drawn into a mouth at a lower end of an injection tube, and water is ejected from a mouth at an upper end of the injection tube. The ejected water is deposited into an interior of the hollow buoy thereby augmenting a water reservoir therein. And water flows from the water reservoir to and through a water turbine, thereby energizing a generator, power electronics, and an electrical load. A novel water-turbine effluent buffering tube, or chamber, smooths pressure variations felt across the water turbine.
