Abstract

A pump, e.g. for wave energy conversion, comprises a length of hose 16 reinforced by at least one inextensible multi-filament strand, or parallel multi-filament strands, wound helically about it which during the application of torsion or tension to the hose is wound up, or has its helix angle reduced, so as to constrict the hose. In the embodiment shown, hose length 16 is subjected to torsion as two rafts 10 and 11 pivot about an axis x due to wave movements, but in an alternative embodiment a hose length transverse to axis x is subject to tension. In another embodiment one end of the pump 16 is moored to the sea bed or a submerged platform while its top end is secured to a buoy which moves up and down with the waves. <IMAGE>
