Abstract

A wave actuated pump comprises an outer cylinder 4 and a piston rod 3, 7 with a piston head 6, defining a primary pump chamber 5 between the cylinder 4 and the piston rod 7 and a secondary pump chamber 8 within the connecting rod 7. The secondary chamber 8 is permanently connected to the pressurised fluid via inner tube 12 without a non-return valve, so the piston 6 is biased to the retracted position. There may also be an additional chamber 9, which draws water in via inlet filter 20 on the upstroke, and returns water to the primary chamber on the downstroke. Because the additional chamber 9 has a greater volume than the primary chamber (because of the connecting rod) some of the water will flow out to back flush the filter.
