Description

簧片阀组件
技术领域
本发明涉及引擎零件领域。具体地说，本发明涉及簧片阀组件领域。更具体地说，本发明涉及2-冲程引擎中用的簧片阀组件。
背景技术
图1是一传统2-冲程引擎簧片阀的实施例。簧片阀10包括一V-形的底座12，可弯曲的簧片瓣14，和限制件16。底座大体上是空心的，并且有许多由簧片瓣14盖住的孔。运作中，空气流入底座12的中心，并通过在底座12上的孔，将簧片瓣14向后推向限制件16。当空气流向相反时，簧片瓣14稳固地靠在底座上，盖住孔，因而大大地阻碍空气流动。
传统2-冲程引擎簧片阀有一个问题是簧片瓣14的磨损。每分钟8,000转时，一个簧片瓣14每秒开合133次。簧片瓣14的疲劳需要簧片瓣14作定期的替换。所以需要一种能减少簧片瓣14磨损的簧片阀组件。
图2是一种较近期的簧片阀组件图。簧片阀20包括一W-形的底座22，可弯曲的簧片瓣24，防护件26，和一内限制件28。这种簧片阀20的设计形成一较宽的孔以使空气流过和改善引擎性能。另外，从为了使簧片阀20能够流过比传统簧片阀10更多的气流来看，靠在防护件26上的簧片瓣24不必弯曲更多，因为气流可流过靠在内限制件28上的簧片瓣24。簧片瓣24运动半径的减少，令簧片瓣24的磨损也减少。靠在防护件26上的簧片瓣24用螺丝30固定于防护件26和底座22之间。靠在内限制件28上的簧片瓣24由底座22和内限制件28中的簧片保持架固定在应有的位置。最后，簧片阀20用由螺丝30固定在底座22上的凸缘32固定在引擎内。
较近期的簧片阀20设计有几个问题。一个问题是使底座22与凸缘32，以及使底座22与防护件26固定的螺丝30。所要求的螺丝30必需特别订购，故而增加组件的成本。并且，在正常使用和维修中，螺丝30需要反复拆装，螺丝30和螺丝孔易磨损。螺丝30的磨损情况可能导致螺丝30脱离簧片阀20，并落入引擎中，严重地损坏引擎。所以，需要一种没有可落入引擎中心螺丝30的簧片阀组件。
簧片阀20设计的另一个问题是安装的时间。用各类工具来安装许多零件及螺丝，令制作簧片阀20的组装时间增多。劳工成本导致簧片阀20变得十分昂贵。理想的是不需要使用任何工具，而簧片阀组件能扣合一起。
发明内容
本发明是这样实现的：本发明设计了一种簧片阀，其能迅速和容易地组装而没有可能滑入引擎的外来的紧固件。在本发明的设计中，凸缘与簧片阀底座作机械式联锁，以及簧片瓣固定在凸缘与底座之间的应有位置而不用任何紧固件。
所以，本发明的一目的是避免使用单个紧固件来组装簧片阀。
本发明的另一目的是避免使用工具来组装簧片阀。
本发明的再一目的是令簧片瓣的使用寿命达至最长。
本发明的又一目的是令通过簧片阀的要求气流量达至最大。

具体实施方式
如图3所示，本发明的簧片阀组件40包括：一簧片保持架42、一承座44和簧片瓣46。承座44可单独地与簧片保持架42联锁。按本文中的定义，可单独地联锁是指，不必使用单个零件使承座44与簧片保持架42连接。正如”可联锁”一词所含意思那样，承座44和簧片保持架42是可分开的。簧片瓣46可拆卸地固定在簧片保持架42上。
在一实施例中，簧片瓣46以承座44固定在簧片保持架42上。如图3中所示，这是承座44的几个可能的实施例中之一。承座44是一个凸缘44a，小凸片48在簧片保持架42中形成。在其中形成孔50的簧片瓣46装配在小凸片48上。凸缘44a有凹槽52，以接纳小凸片48，由此使承座44与簧片保持架42联锁，并使簧片瓣46固定在应有的位置。
在一实施例中，如图4所示，簧片保持架42呈W-形。所述簧片阀组件40是这样设计的，簧片瓣46以簧片保持架42的底座54为枢轴而转动，以打开簧片保持架42的末端56，以使气流从底座54流向末端56。当簧片瓣46打开，末端56的开口约与底座54一样宽，跟传统簧片阀10情况一样。W-形簧片保持架42的好处是无一簧片瓣46需要较传统簧片阀10上的簧片瓣14多转动，便可在末端56产生相同大小的开口。枢轴转动的减少令簧片瓣46磨损减少，并且加快簧片瓣46可能对气流方向变化起作用的速度。当簧片瓣46每秒开和关超过100次时，这种速度是特别重要的。
在另一实施例中，簧片瓣46被固定在不同的高度上。簧片阀组件40的外围从底座54侧向末端56侧逐渐收窄。簧片瓣46的不同固定高度使组件40与外围环境一致。为进一步改善这一实施例与环境的一致性，可将簧片限制件58加在承座44上，该簧片限制件局部地沿簧片瓣46侧向上延伸，但不延伸到末端56。
在再一实施例中，簧片保持架42还包括至少一翼尖60，以改进组件的空气动力学。
在又一实施例中，承座44还包括至少一簧片限制件58。簧片限制件58用来防止簧片瓣46转动太多。簧片限制件58应该至少部份地垂直地从凸缘44并至少部份地沿簧片瓣46向上延伸。簧片限制件58可略呈弧形，以与簧片瓣46的自然弯曲一致。
在再又一实施例中，簧片瓣46包括用一插入件64可拆卸地与簧片保持架42固定的内簧片瓣62和以凸缘44a可拆卸地与簧片保持架42固定的外簧片瓣66。这一实施例要求簧片保持架42呈W-形或其它多个V-形(其中W-形状是等同相邻的V-形状)。理想的是插入件64可独立地与簧片保持架42联锁，以便簧片瓣46固定在应有的位置。在这一实施例中，内簧片瓣62和外簧片瓣66之间唯一的区别在固定方法。使这一实施例进一步收窄，其中内簧片瓣62的顶部设置在外簧片瓣66顶部之上。
一实施例的簧片阀组件40包括可用人手使承座44与簧片保持架42联锁。可人手联锁应理解为不用任何工具，譬如螺丝刀，可用人手使承座44与簧片保持架42联锁。
如图6所示，另一实施例的承座44是一槽式接纳件44b。槽式接纳件44b通常安装在引擎、马达或机器里，其中，簧片阀组件40得以使用。簧片瓣46安装在簧片保持架42后，簧片保持架42牢固地滑入槽式接纳件44b中。通过把簧片瓣46设计成在槽式接纳件44b内向下延伸，槽式接纳件44b则可使簧片瓣46与簧片保持架42固定。
