ABSTRACT:
The invention provides a pump in the form of a length of hose reinforced by at least one extensible 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 a torsion pump the reinforcement is unbalanced, meaning that there is no opposite helix, but in a tension pump reinforcement strands are wound about the hose in opposite senses providing a balanced structure.
Preferably means is provided whereby relative movement between two members 10 and 11 caused by waves is used to distort and relax the length of hose 16, the resulting changes in its internal volume serving to pump water between inlet and outlet lines controlled by non-return valves 20 and 22. The hose length 16 is subjected to torsion as two rafts 10 and 11 pivot about an axis x, but in an alternative embodiment a hose length transverse to axis x is subject to tension.
