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。
本发明提供了一种簧片阀组件，其包括：一簧片保持架；一能独立地与所述簧片保持架联锁的承座；和多片可拆卸地与簧片保持架固定的簧片瓣；所述簧片瓣保持在所述承座和所述簧片保持架之间而不采用任何单独的紧固件。

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。
