Abstract
An apparatus and method are provided for expelling a fluid, including vapor and liquid sprays. A spray is expelled at high velocities from a heated chamber via an exit valve. The chamber includes a flow member or structure that directs and controls the flow of the fluid from an inlet orifice to an outlet orifice along a non-linear path. This prevents the liquid from moving in a wave motion within the chamber if the apparatus is moved.
Claims28
Apparatus for expelling a fluid comprising;
- a reservoir for storing the fluid;
- a chamber;
- an inlet orifice to the chamber;
- an inlet valve;
- an outlet orifice from the chamber;
- an outlet valve;
- at least one heater to heat the fluid within the chamber, such that a temperature and a pressure of the fluid are raised when the inlet valve and outlet valve are closed, causing at least a portion of the fluid within the chamber to change state;
- a flow member to direct and control a flow of fluid from the inlet orifice to the outlet orifice along a non-linear path;
- and
- whereby in use, fluid is expelled from the outlet orifice of the chamber by a vapor explosion process.

A method for expulsion of a fluid from a chamber, comprising:
- supplying fluid from a reservoir to the chamber via an inlet orifice by opening an inlet valve to the chamber;
- directing the fluid inside the chamber to flow via a non-linear path to an outlet orifice via an outlet valve;
- whilst the fluid is inside the chamber and the inlet and outlet valves are closed, heating the fluid to a temperature which is equal to or greater than a saturation point of the fluid at atmospheric pressure, such that at least a portion of the fluid changes state;
- and
- opening the outlet valve such that fluid is expelled from the outlet orifice by a vapor explosion process.
