Abstract

Embodiments of the invention provide dry gaseous fluid pump apparatus comprising: a fluid inlet and a fluid outlet; at least one pump body having an internal wall defining an internal pump chamber thereof; a compression member provided within the pump chamber; and valve means being operable selectively to allow fluid to be drawn from the fluid inlet and into the pump chamber when at least a portion of the compression member is translated in a first direction and to be exhausted from the pump chamber through the fluid outlet when said at least a portion of the compression member Is translated in a second direction opposite the first.
