Abstract
First and second structures are connected by helical fibers. The orientation between the first and second structures are changed, and by doing so, the positions of the helical fibers are correspondingly changed. The position of change of the helical fibers can be used for a pumping effect, or to change some other fluidic characteristics. One other fluidic characteristics, for example, may use the movement of the helical fibers as a valve.
Claims24
A fluid-characteristic changing structure, comprising:
- first and second structures, at least one of which is movable relative to the other;
- and
- a plurality of spring-biased connecting parts, connecting said first and second structures, moving to change a fluidic characteristic of a chamber defined between said connecting parts.
A method, comprising:
- connecting first and second structures using a plurality of spring biased connecting parts;
- and
- moving at least one of said first and second structures relative to the other to change a fluidic characteristic of a chamber defined between said connection parts.
An apparatus, comprising:
- first and second substantially ring-shaped structures;
- a plurality of helical connecting parts, connecting between said first and second substantially ring shaped structures;
- and
- an actuating part, which is actuated to change an orientation of said first and second ring-shaped structures to cause a change in fluidic characteristic.
