摘要： A fuel delivery system for a combustion engine has a fuel tank which defines an access hole preferably communicating through either the top wall or bottom wall of the tank. An associated top or bottom flange, both having a fuel channel for flowing fuel out of the tank, sealably covers the access hole. A fuel pump module is located in the fuel chamber of the tank and has a universal, structural, pod which engages either the top or bottom flange while preferably maintaining an axial upright position. The pod defines an axially extending first bore for housing a fuel pump and preferably an electric pump motor and a second bore defined by a cylindrical inner face and spaced radially outward from the first chamber for housing a reversible filter cartridge of the module. The pod also has a fuel discharge nozzle which generally defines a counter bore that communicates axially with the second bore. Fuel flows into the pump through an inlet defined by the pod and pressurized fuel flows from the pump and into the second bore via a fuel passage preferably defined by the pod. The filter cartridge preferably has a filter element generally spaced from the pod within the second bore for filtration efficiency by a primary end retainer and an opposite secondary end retainer. The end retainers generally seal to the pod within the second bore thus flowing all of the pressurized fuel from the fuel passage and through the filter element before being discharged from the second bore as supply fuel and/or bypass fuel. Preferably, filtered fuel flows through the primary end retainer as system supply fuel to a combustion engine and the remaining filtered fuel flows through the secondary end retainer as bypass fuel back into the fuel tank chamber.
摘要翻译：用于内燃机的燃料输送系统具有一个燃料箱，该燃料箱限定了优选通过罐的顶壁或底壁连通的进入孔。具有用于将燃料从罐中流出的燃料通道的相关联的顶部或底部凸缘可密封地覆盖进入孔。燃料泵模块位于燃料箱的燃料室中并且具有通用结构的荚，其接合顶部或底部凸缘，同时优选地保持轴向直立位置。舱体限定轴向延伸的第一孔，用于容纳燃料泵，优选地包括电动泵电动机和由圆柱形内表面限定并与第一室径向向外隔开的第二孔，用于容纳模块的可逆滤筒。荚壳还具有燃料排出喷嘴，其通常限定与第二孔轴向连通的反向孔。燃料通过由容器限定的入口流入泵中，并且加压的燃料经由燃料通道优选地由容器限定，从泵流入第二孔。过滤器滤芯优选地具有过滤器元件，该过滤器元件在第二孔内通常与容器间隔开，以便通过主端保持器和相对的次端保持器进行过滤效率。端部保持器通常在第二孔内密封到容器，从而在从第二孔作为供应燃料和/或旁路燃料排放之前将所有加压的燃料从燃料通道流过并通过过滤元件。优选地，过滤的燃料流过主端保持器，因为系统向燃烧发动机供应燃料，并且剩余的过滤燃料作为旁路燃料流回到燃料箱室中。
