    • A pump assembly for dispensing fluent material from within a container includes a tank and a piston defining therebetween a pump chamber and movable relative to each other to pump fluid from the container into and out of the pump chamber. A poppet interposed between the tank and the piston extends at one end thereof into the inlet conduit for the pump chamber and at the opposite end into the exhaust conduit. When the tank and piston are moving relative to each other to draw fluid from the container into the pump chamber, the end of the poppet extending to within the exhaust conduit engages against a valve seat defined in the exhaust conduit to close the exhaust conduit. The other end of the poppet extending to within the inlet conduit is frictionally engaged within the inlet conduit and the drag forces thus effected upon this end of the poppet operate to enhance the sealing effect of the opposite end of the poppet to close the exhaust conduit thereby permitting fluid to be drawn into the pump chamber. The minimum cross sectional area through which fluid flows from the container into the pump chamber through the inlet conduit is determined by the dimensions of the inlet conduit and the end of the poppet extending thereinto. By maintaining, during the exhaust stroke of the piston, the minimum cross sectional area of the inlet conduit substantially less than the flow area of the exhaust conduit, fluid within the chamber will tend to follow the path of least resistance and flow out of the exhaust conduit rather than back into the container despite the fact that the inlet conduit is maintained open during this exhaust stroke and despite the fact that no valve means tending to close the inlet conduit at the beginning of the exhaust stroke are provided.
    • 用于从容器内分配流体材料的泵组件包括容器和在其间限定泵室的活塞,并且可相对于彼此移动以将流体从容器泵入和流出泵室。 插入在罐和活塞之间的提升阀在其一端处延伸到用于泵室的入口管道中,并且在相对端延伸到排气管道中。 当罐和活塞相对于彼此移动以将流体从容器吸入泵室时,延伸到排气管道内的提升阀的端部与限定在排气管道中的阀座接合以关闭排气管道。 提升阀延伸到入口管道内的另一端在入口管道内摩擦接合,并且由此在提升阀的该端部处实现的阻力作用,以提高提升阀的相对端的密封效应,从而关闭排气管道 允许流体被吸入泵室。 流体通过入口导管从容器流入泵室的最小横截面积由入口导管的尺寸和延伸到其中的提升阀的端部确定。 通过在活塞的排气冲程期间保持入口导管的最小横截面面积基本上小于排气管道的流动面积,腔室内的流体将倾向于沿着最小阻力的路径并流出排气 导管,而不是回到容器中,尽管在该排气冲程期间入口管道保持打开,并且尽管事实上提供了在排气冲程开始时趋向于关闭入口导管的阀门。
