    • Disclosed is a unique filter assembly for ensuring replacement cartridge compatibility in filtration systems having replaceable filter cartridges with lugged mounting systems. One representative filter assembly includes a representative cartridge member having a body portion for enclosing filter media and a neck portion depending therefrom. The representative neck portion of the representative cartridge includes at least one axial inlet port for directing unfiltered fluid into the body portion and at least one axial outlet port for directing filtered fluid out of the body portion. The representative neck portion also has at least two representative lugs depending radially outwardly therefrom, wherein at least one lug defines a keyed engagement surface, a leading inclined cam surface and a trailing inclined cam surface. The at least two representative lugs wherein at least one lug defines a keyed engagement surface, a leading inclined cam surface and a trailing inclined cam surface could be operatively positioned on other components of the representative filter assembly as well.
    • 公开了一种独特的过滤器组件,用于确保具有带有安装系统的可更换滤芯的过滤系统中更换墨盒的兼容性。 一个代表性的过滤器组件包括具有用于封闭过滤介质的主体部分和从其悬挂的颈部的代表性的盒构件。 代表性墨盒的代表性颈部包括至少一个轴向入口端口,用于将未过滤的流体引导到主体部分中,以及至少一个轴向出口端口,用于将过滤的流体引导出主体部分。 代表性的颈部还具有从其径向向外的至少两个代表性凸耳,其中至少一个凸耳限定了键合的接合表面,前倾斜凸轮表面和后倾斜凸轮表面。 至少两个代表性的凸耳,其中至少一个凸耳限定了键合的接合表面,前导倾斜凸轮表面和后倾斜凸轮表面也可操作地定位在代表性过滤器组件的其他部件上。

    • A filtering device (10) includes a head (12) intended to be permanently installed in a fluid dispensing machine and a disposable canister (14) therefor. A central chamber (34) is formed in the head which chamber is in communication with an inlet port (36) and an outlet port (38) for receiving an unfiltered liquid and supplying a filtered liquid, respectively. The disposable canister (14) has a flask shaped main body (54) with a flat top (56) and a neck (64) of substantially uniform diameter on the top. The neck (64) fits in the central chamber. A tube (72) extending through the neck (64) defines an annular clearance (82) between the tube (72) and the interior of the neck (64) which annular clearance (82) is in fluid communication with the inlet port (36). The opening into the tube (72) located at the top of the neck (64) is in fluid communication with the outlet port (38) in the head (12). A pair of tab receptacles (22, 24) on the head and a complementary pair of tabs (58, 60) on the canister are engageable with one another by 1/4 rotation of the canister to lock the canister to the head.
    • 过滤装置(10)包括旨在永久地安装在流体分配机器中的头部(12)和用于其的一次性罐(14)。 中心室(34)形成在头部中,该室与入口端口(36)和出口端口(38)连通,用于接收未过滤的液体并分别供应过滤液体。 一次性罐(14)具有在顶部具有平坦顶部(56)和基本均匀直径的颈部(64)的烧瓶形主体(54)。 颈部(64)装配在中央室中。 延伸穿过颈部(64)的管(72)在管(72)和颈部(64)的内部之间限定环形间隙(82),环形间隙(82)与入口端口(36)流体连通 )。 位于颈部(64)顶部的管(72)的开口与头部(12)中的出口(38)流体连通。 头部上的一对突片插座(22,24)和罐上的互补的一对突片(58,60)可通过罐的1/4转而彼此接合,以将罐锁定到头部。
