Pressure-regulating hydrodynamic pump and wave engine

A hydrodynamic-pump, comprising:

• a hollow buoyant reservoir;
• an injection tube fluidly coupled to the hollow buoyant reservoir, the injection tube configured to impel water into the hollow buoyant reservoir when the injection tube oscillates vertically beneath a waterline;
• a fluid path having an inlet fluidly coupled to the hollow buoyant reservoir, the fluid path having an outlet, and the fluid path configured to remove water from the hollow buoyant reservoir;
• an air ingestion pipe coupled to the hollow buoyant reservoir;
• a separation gallery coupled to the air ingestion pipe and fluidly coupled to the hollow buoyant reservoir;
• and
• an air inlet conduit coupled to the air ingestion pipe.

• a fluid path having an inlet fluidly coupled to the hollow buoyant reservoir, the fluid path having an outlet, and the fluid path configured to remove water from the hollow buoyant reservoir;
• an effluent buffer chamber coupled to the hollow buoyant reservoir and to the fluid path, the effluent buffer chamber configured to stabilize short-term or transient swings in net pressure of water flowing from the hollow buoyant reservoir and into the fluid path;
• and
• a reservoir pressure-stabilizing trompe coupled to the hollow buoyant reservoir and coupled to the effluent buffer chamber and coupled to ambient air, the reservoir pressure-stabilizing trompe configured to continuously adjust an average pressure of an air pocket in the hollow buoyant reservoir so as to maintain an elevated rate of water effluence from the fluid path, and to maintain an elevated rate of water addition to the hollow buoyant reservoir from the injection tube.
