Abstract
A miniature pump including a first chamber, a second chamber, a deformable membrane provided within the second chamber that divides the second chamber into first and second sub-chambers, the second sub-chamber defining a reservoir configured to contain liquid to be dispensed, a passage that connects the first chamber to the first sub-chamber, and an outlet in fluid communication with the reservoir, wherein pressurized fluid within the first internal chamber flows through the passage and into the first sub-chamber to compress the deformable membrane and cause liquid contained within the reservoir to flow out from the reservoir through the outlet and wherein the deformable membrane does not generate significant restoring forces when it is deformed and, therefore, will not return to its initial undeformed shape unless the reservoir is refilled.
