AT B7 五、發明説明(1 發明範疇 本發明有關於控制流體流量所用的裝置的一般範•,而 更明確言之,有關一種自行清潔之計量裝置。 早先技藝 大家都知道,在作調節用的諸閥巾,操作上的 會引起摩ί察’摩擦於是產生一磁滯現象,該類摩擦全都是 比較大的·,因為存在於任何流體中的污染物,會在接觸引 導表面上衍生”膠質"的產物。 +就以在膽噴射或满輪螺聚發動⑽稱為渴輪機)的燃油 噴射系統中所使用的計量裝置的特別案例來說,這個磁滯 現象導致該噴射流量的不均勾性,極可能傷害到該渦輪機 的正當運作’尤其是在將其起動的時候。 這項問題的解決辦法,傳統上,在於降低摩擦的表面面 積。可是,這個解決辦法,會有增加其餘操作表面接觸的 磨耗的主要缺點,從而限制了該計量裝置的壽命。另一解 決辦法,在於降低該接觸表面的摩擦係數。可是,這個解 決辦法,當膠質或/及污染物積聚到太大的時候,事實證明 其有所不足。 本發明之目的及定義 因此,本發明的一目的,在於消除這些缺點,藉提出一 種流體計量裝置’其因經過該裝置的流體的運動,使顯著 降低、或甚至消除任何積聚的污染物,成為可能。 這些目的的達成,係藉助-用以計量-流體從-供應源 到一使用此流體的裝置的流體計量裝置,此裝置包括一针 -4-

件就令人滿足了。 田。亥槽溝的深度的值應加計算,以使適應所需流體 、I·•里並避免在5玄使用裝置中有過分大的壓頭損失。 須加強調的,在圖示範例中,雖然該溝係製作在該閥10 上,十分明顯地,它也可以製作在套筒12上,這是完全可 以想見的。在這兩種可替換的型態中,或者有一個型態, 其槽溝還.藉確有對該接觸表面的括除,而使其有可能去除 積聚在接觸表面上的污染物。此外,流體的沖掃效果,其 在這些由該螺旋形槽溝所構成的引導裝置的水平上,使得 要將這些污染物排放到使用該流體的裝置20中,成為可炉 ’並因此達成該計量闊的自行清潔的目的。
