Abstract

在图2中示出的无气喷头组件100中，缸112包括喷头114且位于死区116的一端。关闭阀118由球120和阀座122构成。针阀座122已经被配合至每一个喷头组件100(参见图2)。通过将喷头114和阀座组件(关闭阀)118配合为一体，密封件124可以从“死区”116移出，因此减小了喷射容积和能量储存。

Description

无气喷头
技术领域
本申请要求于2010年1月27日提交的、美国申请序列No.61/298,775的利益，其内容通过参考并入本文。
背景技术
在美国专利No.4,165,836和No.6,702,198中公开了典型的无气喷头，上述专利的内容通过参考并入本文。在当前可反转喷头应用中，普遍的做法是将势能储存在O形环中，O形环位于致动喷枪的机械流体密封件之前并位于喷头之后。高势能储存材料的示例是O形环。其以下述方式储存能量：当喷枪关闭时，密封件能量降低并向油漆工的机件上喷射。
发明内容
本发明的目标是将无气喷头中的能量储存最小化从而将喷射容积最小化。该喷头组件的构造不同于现有技术的装置。针阀座已经被配合至每一个喷头组件。通过将喷头和阀座组件配合为一体，密封件可以从“死区”移出，因此减小了喷射容积。本发明消除了机械流体关闭阀之前的所有O形环，因此将喷射最小化。
本发明的这些和其它目标、优点将从结合附图进行的以下描述充分展示出来，其中在整个数幅附图中，相似的附图标记涉及相同或类似的部件。
附图说明
图1示出现有技术的喷头组件。
图2示出本发明的喷头组件。
具体实施方式
在诸如图1中示出的现有技术的可反转喷头组件10中，缸12包括已知设计的喷头14。死区16位于喷头14和关闭阀18之间，该关闭阀18由球20和阀座22构成。O形环密封件24位于死区16中并且可以储存能量和释放能量。当密封件24暴露于典型的无气喷涂压力、典型地是2000psi至3000psi时，密封件24是可压缩的。虽然任何材料理论上都是可压缩的，但是当在此处使用时，该术语指示了当暴露于这样的压力时可以被大致压缩和释放的材料。金属和类似的材料在它们的通常形式下不被认为是可压缩的。
在图2中示出的本发明的喷头组件100中，缸112包括喷头114且位于死区116的一端。关闭阀118由球120和阀座122构成。针阀座122已经被配合至每一个喷头组件100(参见图2)。通过将喷头114和阀座组件(关闭阀)118紧密配合为一体，密封件124可以从“死区”116移出，因此减小了喷射容积和能量储存量。
在当前可反转喷头应用中，普遍的做法是将势能储存在O形环中，O形环位于致动喷枪的机械流体密封件之前并位于喷头之后。高势能储存材料的示例是O形环。它们储存能量从而当喷枪关闭时，密封件能量降低并向油漆工的机件上喷射(spit)。本发明消除了机械流体关闭阀之前的所有O形环，因此将喷射最小化。
可以预期的是，在不脱离由下述权利要求限定的本发明的精神和范围的情况下，可以做出多种变化或修改。
