Abstract

具有低/高流速的两组分喷枪，其允许操作者以低流动在限制区域喷射而不需要改变混合模块。低流动降低了不需要的“喷射回流”且有助于减少材料浪费。气动活塞(12)的行程决定开启/关闭流体流动，该行程可在行进时选择成：关闭流体口(14)，停止流体流动；部分开启流体口(14)，限制流体流动；或完全开启流体口(14)以允许最大流动。可借助于简单的多位置的机械式停止柱塞(16)限制气动活塞(12)的行程。停止棒(22)可连接到旋钮(18)或其他操作者输入端且被旋转或被调节到期望的位置。

Description

气动的两组分喷枪中的可变流体流动
技术领域
本申请要求2007年9月11日递交的美国申请60/971,300的优先权，其整体内容被结合在此，作为参考。
背景技术
用于喷涂例如快速固化泡沫的多组分材料的喷枪是已公知的。
发明内容
本发明允许操作者以可变流速喷射两组分材料。气动活塞行程决定开启/关闭流体流动，该行程可在行进时(on the fly)选择成：阻止流体流动的关闭流体口，部分开启流体口，限制流体流动，或全部开启流体口以允许最大流动。可借助于简单的多位置的机械式停止件来限制气动活塞的行程。该停止件连接到旋钮或其他操作者输入端且被旋转或被调节到用于相对应的关闭，部分的流动，或完全流动的期望位置。此外，可选择的活塞行程的设计结合了用于部分开启位置的微调调节。这一特征允许操作者决定在部分开启位置上限制流动到什么程度。
从以下结合附图作出的说明，本发明的这些和其他目标和优点将更加充分的显而易见，其中在所有的几个视图中相同的附图标记表示相同或相似的部分。
附图说明
图1表示处于关闭位置的活塞行程停止机构。
图2表示处于部分开启位置的活塞行程停止机构。
图3表示处于全部开启位置的活塞行程停止机构。
图4表示空气气缸盖上的可变停止位置。
图5表示处于关闭位置的喷枪。
图6表示处于部分开启位置的喷枪。
图7表示处于全部开启位置的喷枪。
具体实施方式
本发明10允许操作者以可变流速喷射两组分材料。气动活塞12行程决定开启/关闭流体流动，该行程可在行进时选择成：关闭流体口14(见图1和5)，阻止流体流动，部分开启流体口14(见图2和6)，限制流体流动，或全部开启流体口14(见图3和7)，以允许最大流动。可借助于简单的多位置的机械式停止柱塞16限制气动活塞12的行程。停止棒22可连接到旋钮18或其他操作者输入端且被旋转或被调节到用于相对应的关闭，部分的流动，或全部流动的期望位置，由此安置停止棒柱塞16。
此外，选择活塞行程的设计结合了用于部分开启位置的微调调节。空气气缸盖20通过螺纹可调节进出，以改变部分地开启/低流动位置。这一特征允许操作者决定在部分开启位置上限制流动到什么程度。图4表示具有可变深度凹槽20a，20b和20c的气缸盖20，所述凹槽用于将停止棒柱塞22分别安置在关闭，部分开启和完全开启位置。
在不偏离由所附权利要求限定的本发明的精神和范围的情况下，可以考虑对于可变流动多组分喷枪进行各种改变和改进。
