Abstract

See full text

A pump with an outer housing defining an enclosure, an inlet for admitting fluid into the outer housing and an outlet for expelling fluid from the outer housing, a piston for selectively modulating a first fluid pressure, such that the first fluid pressure is associated with a location proximate the inlet, and a member that selectively isolates a second pressure associated with a location proximate the outlet from the first fluid pressure. The pump may also include a first chamber within the outer housing for receiving fluid admitted into the pump from an ambient environment and through an inlet to the pump, a second chamber within the outer housing for receiving fluid from the first chamber, and a piston that both (i) selectively controls the flow of fluid from the first chamber to the second chamber and (ii) selectively expels the fluid from the second chamber into the ambient environment.
