ABSTRACT:
A wave-actuated bilge pump for pumping foul bilge gases from a boat. The pump includes a generally inverted U-shaped section of hollow tubing with generally downwardly directed legs having open ends. One of the ends is positioned to receive bilge gases from within the boat, and the other end is immersed below the surface of the water outside the boat. A freely-opening check valve permits bilge gases to flow within the tubing only away from the fume-receiving end. A gas-escape port opened to the atmosphere is provided in the tubing above the lower, open tubing end immersed in the water, and a second, freely-opening check valve is provided to permit flow of bilge fumes through the port only outwardly of the tubing of the atmosphere. Wave-action causes the level of water in the exterior leg of the tubing to rise and to fall such that bilge gases are drawn into the tubing as the water level falls, and the gases are exhausted from the tubing as the water level rises.
