摘要： A pump having a body including at least two axially aligned pumping chambers each of which contains an actuator having a main central rigid portion and a peripheral sealing ring retained in a clearance space and under radial compression in non-sliding fluid-tight relation between the main central portion and a lateral wall of the pumping chamber, such main central portions of the actuators being joined by a rigid connecting rod having further sealing rings embracing it and engaged with the side walls of respective pumping chambers to form a resiliently supported unit which is reciprocable axially of the pumping chambers and is driven by provision of contact faces on the connecting member spaced apart along said axis and facing in opposite directions, and between which is received the outer race of an anti-friction bearing carried on an eccentric of a drive spindle mounted for rotation in the pump body at right angles to the pumping chamber axis.

摘要： A pump comprising a body having at least one chamber and preferably two axially spaced and aligned pumping chambers, each such pumping chamber communicating at opposite ends respectively with a pump inlet and a pump outlet and containing an actuator reciprocable longitudinally of the pumping chamber by drive means, the actuator having a rigid main central portion and a peripherally extending elastic sealing ring in non-sliding fluid-tight engagement with a lateral wall of the pumping chamber and having mounted thereon actuator valve means controlling the flow of fluid from the inlet to the outlet of the pump, the pumping chambers communicating at their outlet ends with manifold passageways in the body of the pump which in turn communicate with respective passageways in an outlet duct situated on opposite sides of a longitudinally extending web therein terminating at a position spaced from the downstream end of the outlet duct to provide for cyclic flow of the pump fluid out of one pumping chamber and into the other around the downstream end of said web when shut off occurs at the pump outlet, fluid inductance means and fluid capacitance means with the latter operative throughout the pumping cycle being provided to limit the internal pressure to a safe value under shut off conditions.
摘要翻译：一种泵，包括具有至少一个室的主体，并且优选地具有两个轴向间隔开和对准的泵送室，每个这样的泵送室分别在相对的端部处连通泵入口和泵出口，并且包含通过驱动装置沿泵送室纵向往复运动的致动器致动器具有刚性的主中心部分和周向延伸的弹性密封环，其与泵送室的侧壁非滑动流体密封接合并且安装在其上的致动器阀装置，其控制流体从入口到出口泵的泵室在泵的出口端与泵的主体中的歧管通道连通，泵的主体又与位于纵向延伸的纤维网的相对侧上的出口管道中相应的通道连通，其终止于与下游出口管道的端部，以提供泵流体从一个泵的循环流动当在泵出口处发生切断时，流体电感装置和流体电容装置在整个泵送循环期间被运行，以在关闭时将内部压力限制到安全值关闭条件。
