    • 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, the valve means being arranged to be actuated by actuator means under the control of control means to perform at least one selected from amongst the functions of allowing fluid to be drawn from the fluid inlet into the pump chamber and allowing fluid to be exhausted from the pump chamber through the fluid outlet, the apparatus comprising a linear drive assembly operable to drive the at least a portion of the compression member to and fro within the pump chamber.
    • 本发明的实施例提供了一种干式气态流体泵装置,包括:流体入口和流体出口; 至少一个泵体,其具有限定其内部泵室的内壁; 设置在所述泵室内的压缩构件; 以及当所述压缩构件的至少一部分沿着第一方向平移并且当所述压缩构件的至少一部分在所述第一方向上从所述泵室排出时,所述阀装置选择性地可操作地允许流体从所述流体入口被抽出并进入所述泵室, 所述压缩构件的至少一部分在与第一方向相反的第二方向上平移,所述阀装置被布置成在控制装置的控制下由致动器装置致动,以执行从允许流体成为的功能中选择的至少一种 从流体入口抽出到泵室中并允许流体通过流体出口从泵室排出,该装置包括线性驱动组件,其可操作以在泵室内来回驱动压缩构件的至少一部分 。
