摘要： In a self-cleaning filter assembly (10), a filter element (31) is fixed within a housing (17) and spaced from the peripheral wall (21) thereof by an annular solids collection space (34) in turn communicating with a solids outlet (63). An inlet (56) introduces pressurized liquid to be filtered circumferentially into the solids collection space. A shower assembly (81) rotates and includes an eccentric portion (83) having jets (91) aimed outward close to the inner surface of the filter element. Backwash liquid enters the rotating shower assembly under pressure for continuously pushing solids off the outer surface of the filter element as the shower assembly circumferentially advances. Filtrate from inside the filter element passes through a filtrate outlet from the housing. A solids outlet valve (163) responds to a preselected increase in liquid pressure differential between the inlet and filtrate outlet to increase venting of the annular solids collection space. A filtrate outlet valve (181) may simultaneously close to direct all liquid flow out the solids outlet.

摘要翻译： 在自清洁过滤器组件（10）中，过滤器元件（31）固定在壳体（17）内并且通过环形固体收集空间（34）与其周壁（21）间隔开，所述环形固体收集空间（34）又与固体 出口（63）。 入口（56）将要被过滤的加压液体周向引入固体收集空间。 淋浴器组件81旋转并且包括具有向外靠近过滤元件的内表面的射流（91）的偏心部分（83）。 反冲洗液体在压力下进入旋转淋浴组件，以在淋浴器组件周向前进时将固体从过滤元件的外表面上持续推出。 过滤元件内部的滤液从壳体通过滤液出口。 固体出口阀（163）响应入口和滤液出口之间的液压差的预选增加，以增加环形固体收集空间的排放。 滤液出口阀（181）可以同时接近以将所有液体流出固体出口。
