Abstract
This invention generally relates to a pump system, particularly to a vapor-pressure driven micro pump system. This vapor-pressure driven pump system is useful for various situations, especially in a gravity-free environment in space exploration.
Claims20
A vapor pressure driven pump system comprising
- a) an enclosure of supporting structure;
- b) a first chamber inside of said enclosure having a first volatile material;
- c) a second chamber having a second volatile material as a propellant, and a plurality of exit nozzles;
- and
- d) a flexible collapsible diaphragm separating and interconnecting the first and the second chambers within said enclosure, wherein a vacuum at the exit nozzle leads to vaporization of said propellant and displaced by vapor of said first volatile material at nearly constant pressure by moving of said collapsible diaphragm.

A method of a micro propelling system in a gravity free environment comprising
- a) an enclosure of supporting structure;
- b) a first chamber inside of said enclosure having a first volatile material;
- c) a second chamber having a second volatile material as a propellant, and a plurality of exit nozzles;
- and
- d) a flexible collapsible diaphragm separating and interconnecting the first and the second chambers within said enclosure, wherein a vacuum at the exit nozzle leads to vaporization of said propellant (second volatile material) and displaced by vapor of said first volatile material at nearly constant pressure by moving of said collapsible diaphragm.
