Description

可逆無氣噴灑尖端總成
本發明是關於一種無氣噴灑尖端(airless spray tip)。
典型之無氣噴灑尖端被顯示於美國專利第4,165,836及6,702,198號中，其內容被納入參考。於目前之可逆的噴灑尖端應用中；其常見的是具有儲存於O型環中之位能，該等O型環位在致動該噴槍之機械式流體密封件的前面及在該噴灑尖端之後方。高位能儲存材料之範例將為O型環。它們以此一使得當該噴槍被關閉時將該等密封件失能及吐出至該畫家之作品的方式儲存能量。
本發明之目的係使無氣噴灑尖端中之能量儲存減至最小，以使吐出量減至最小。此尖端總成之結構係與先前技術裝置不同。該針閥座已與每一尖端總成匹配。藉由使該尖端及該閥座總成匹配成一體，該密封件可從該‘死區’被移出，如此減少吐出量。本發明消除在該機械式流體關閉閥的前面之所有O型環，如此使該吐出量減至最小。
本發明之這些及其他目的與優點將由以下會同所附圖面作成之敘述更充分地顯現，其中遍及該數個視圖之相像的參考字母意指相同或類似的零件。
於諸如圖1所示先前技術之可逆的尖端總成10中，可旋轉圓柱體12包含習知設計之噴灑尖端14。死區16係位於尖端14及由滾珠20及閥座22所組成的關閉閥18之間。O型環密封件24係位在該死區16中，並可儲存能量及釋放該能量。當暴露至典型的無氣噴灑壓力、典型為2000-3000磅/平方英吋時，密封件24係可壓縮的。雖然任何材料係在理論上可壓縮的，如在此中所使用者，該名詞指示當暴露至此等壓力時大體上可被壓縮及釋放的材料。金屬及類似材料於其普通形式中不被考慮為可壓縮的。
於圖2所示本發明之尖端總成100中，可旋轉圓柱體112包含尖端114並位在死區116的一末端。關閉閥118係由滾珠120及閥座122所組成。該針閥座122已與每一尖端總成100匹配(見圖2)。藉由使該尖端114及該閥座總成(關閉閥)118匹配成一體，該密封件124可從該‘死區’116被移出，如此減少吐出量及能量儲存。
圖2中，尖端總成100包含帽蓋102和可旋轉圓柱體112。帽蓋102包含第一徑向孔104、環狀槽106和肩部108。在圖2所示的尖端總成100中，可旋轉圓柱體112包含第一軸向孔113。圓柱體112另包括尖端114和套筒115，且圓柱體112位於死區116之一端。圓柱體112另包括肩部117，其伸入第一軸向孔113。關閉閥118包括滾珠120，附著於致動機構121、閥座122，和座支撐件 123。閥座122與尖端總成100匹配(見圖2)。噴灑尖端114包含尖端126、環狀突出部128，和噴灑噴口130。噴灑噴口130通過噴灑尖端114從環狀突出部128延伸至尖端126。套筒115包含通過自身的第二軸向孔132。座支撐件123包含上游端134、下游端136，和第三軸向孔138。凸緣140從上游端134伸出並界定出位於座支撐件123之上游端134的環狀凹陷142。閥座122包含第四軸向孔144。死區116包含第二軸向孔132、第三軸向孔142，和第四軸向孔144。藉由使尖端114和閥座總成(關閉閥)118匹配成一體，密封件124可從’死區’116被移出，如此降低吐出量及能量儲存。
可旋轉圓柱體112置於帽蓋102的第一徑向孔104之內。噴灑尖端114設置於第一軸向孔113之內而尖端126面向上游。藉由使環狀突出部128嚙合肩部117，噴灑尖端114被維持於第一軸向孔113之內。套筒115以類似方式設置於第一軸向孔113之內，而第一軸向孔113鄰近尖端114並位於尖端114的上游。第二軸向孔132對齊噴口130。座支撐件123設置於帽蓋102之內。座支撐件123的下游端內136鄰近可旋轉圓柱體112和套筒115。凸緣140的自由端抵靠肩部108以維持座支撐件123的環狀凹陷142。第三軸向孔138和第四軸向孔144對齊以界定出通過關閉閥118的流動路徑。第三軸向孔138和第四軸向孔144也和第二軸向132對齊，第二軸向132與噴灑噴口130對齊以界定出死區116。密封件124位於座支撐件 123徑向向外處並被容納於帽蓋102的環狀槽106之內。
於目前之可逆的噴灑尖端應用中；其常見的是具有儲存於O型環中之位能，該等O型環位在致動該噴槍之機械式流體密封件的前面及在該噴灑尖端之後方。高位能儲存材料之範例將為O型環。它們以此一使得當該噴槍被關閉時將該等密封件失能及吐出至該畫家之作品的方式儲存能量。本發明消除在該機械式流體關閉閥的前面之所有O型環，如此使該吐出量減至最小。
