Abstract

在一个往复式活塞泵中，活塞（34）具有第一或者上端（48）以及第二或者底端50，其中进口52和出口54分别位于这两个端中。进口单向阀（32）位于孔径52内，而出口单向阀42位于孔径54内。如图3中可见，孔径52和孔径54各自分出三个（在优选的实施方案中）流动路径，这些流动路径交错排列并且相互交缠。本发明的关键特征正是在这种活塞中结合了进口单向阀和出口单向阀二者的这些独特的流动路径。

Description

内部波纹管泵的流体路径
技术领域
本申请要求2010年4月30日提交的美国申请序号61/329,663的权益，其内容通过引用结合在此。
背景技术
在一个典型的往复式活塞泵中有一个密封件，该密封件将高压工作流体同泵周围的大气分离开。即使在理想状态下，每次循环时这些密封件可能渗出少量的流体，并且这可能损害密封件的寿命。这种流体可能会固化或结晶并且会被吸回到密封件之中，从而缩短密封件的寿命。历史上处理这种少量渗漏的一种方式就是用一个柔性波纹管密封件12，这创造了一种泵10，它没有暴露的滑动密封件。在这种设计中，泵10的进口14被通路连接穿过这个高压密封件，并且所产生的低压进入室16被波纹管12密封，这产生了一种气密的密封，见图1。这种流体于是必须被通路连接至该泵10的底部，以便在活塞下方经过进口阻塞球而被吸入。历史上的做法是通过在泵上安装一个外部歧管来将该液体通路连接至该主要压油室周围送入泵的进口。
发明的披露
本发明通过创造穿过泵的活塞杆以及活塞的一个通道而不再需要一个外部歧管，见图2。以往的各种设计曾经结合了一个空的活塞杆，但仍然要求用于出口单向阀的一个分开的歧管或者流动路径。本发明将这两个单向阀都结合到活塞之中。这是通过将三个进口和出口流动路径分开60度角交错排列而做到的，见图3。本发明的关键特征正是在这种活塞中结合了进口单向阀和出口单向阀二者的这些独特的流动路径。
从以下结合附图的说明中将会更加全面地展示本发明的这些及其他的目的和优点，在附图中，遍及几个视图中的类似参考符号指代相同或者类似的部件。
附图简要说明
图1示出一个现有技术的波纹管泵。
图2示出本发明的泵的一个截面图。
图3示出活塞及其多个流动路径。
实施本发明的最佳方式
在图2和图3中示出本发明的泵，总体上表示为20。泵20有一个泵进口22，该进口通向进入室24。室24被波纹管密封件26从外部密封住。在中空的活塞杆30中设有多个进入端口28，这些进入端口通向活塞34中的进口单向阀32，该活塞在圆柱状体36中滑动，而该圆柱状体是壳体38的一部分。一个泵出口40被定位于壳体38内。出口单向阀42也位于活塞34内。
本发明通过创造了穿过泵20的活塞杆30以及活塞34的一个通道，不再需要一个外部歧管，如图2中可见。本发明将这两个单向阀32和42都结合在活塞34之中。这是通过将三个进口44和出口46的流动路径分开60度角交错排列而做到的，如图3中所示。
活塞34具有第一或者上端48以及第二或者底端50，其中进口52孔径和出口54孔径分别位于这两个端中。进口单向阀32是位于孔径52内，而出口单向阀42是位于孔径54内。从图3中可见，孔径52和54各自分出三个（在优选的实施方案中）流动路径（进口44和出口46），它们交错排列并且相互交缠。本发明的关键特征正是在这种活塞中结合了进口单向阀和出口单向阀二者的这些独特的流动路径。
在此考虑到对于波纹管泵的流体路径可做不同的改变和调整而不偏离如以下项权利要求所限定的本发明的精神和范围。
