摘要： A fuel filter assembly employs a hand primer and a disposable filter cartridge mounted to a header. The filter cartridge has a filter element which defines an interior chamber for receiving the filtered fuel. The hand primer includes a diaphragm which cooperates with the header to define a reservoir and a valve plate having a plurality of orifices and an axial opening for providing fluid communication between an exit passage of the header and the reservoir and between the chamber and the reservoir, respectively. A first check valve is mounted in the opening and a second check valve is mounted in an axial bore in the first check valve. The first and second check valves are moveable between an open position for allowing flow through the orifices of the valve plate and orifices in the first check valve, respectively, and a closed position for preventing such flow. The filter assembly is primed by pushing the diaphragm downwards, creating a high pressure which moves the first check valve to the open position and the second check valve to the closed position, causing trapped air to be expelled through the orifices and the exit passage. Removing the downwards force allows a spring to return to bias the diaphragm upwards, creating a low pressure which moves the first check valve to the closed position and the second check valve to the open position, and drawing fuel from the interior chamber.
摘要翻译： 燃料过滤器组件使用手动底漆和安装到头部的一次性过滤器滤芯。 过滤器滤芯具有限定用于接收经过滤的燃料的内部室的过滤元件。 手底漆包括隔膜，其与头部配合以限定储存器和具有多个孔的阀板和用于在集管的出口通道和储存器之间以及在室和储存器之间提供流体连通的轴向开口， 分别。 第一止回阀安装在开口中，第二止回阀安装在第一止回阀的轴向孔中。 第一和第二止回阀分别在允许流过阀板的孔和第一止回阀中的孔的打开位置之间移动，以及用于防止这种流动的关闭位置。 过滤器组件通过向下推动隔膜来启动，产生使第一止回阀移动到打开位置的高压力，将第二止回阀移动到关闭位置，从而使被截留的空气通过孔口和出口通道排出。 卸下向下的力允许弹簧返回以向上偏置膜片，产生低压力，其将第一止回阀移动到关闭位置，并且将第二止回阀移动到打开位置，并且从内部室抽取燃料。

摘要： An improved fuel filter cartridge comprises a housing which defines an opening, a filter element enclosed within the housing, and a flow-reversing insert disposed within the housing between the opening and the filter element. The improved filter cartridge is preferably used with a conventional header of the type having a fuel entry port, a fuel exit port, a central first conduit for interiorly defining a first axial fuel passage which is in fluid communication with the entry port of the header. Headers used with the improved filter cartridge also include a second conduit surrounding and cooperating with the first conduit to define a second axial fuel passage therebetween, the second fuel passage being in fluid communication with the exit port of the header, and a base for mounting the filter cartridge thereto. When the filter cartridge is mounted to the base of the header, the insert, filter element and housing cooperate to define a first chamber in communication with the first conduit of the header and to define a second chamber in communication with the second conduit of the header. Fuel delivered to the exit port of the header progressively flows through the second conduit, is guided radially outwardly by the insert, flows through the filter element, flows through the first conduit and, finally, flows into the entry port of the header. Methods of using the improved filter cartridge are also disclosed.

摘要： A display provides an indication of the remaining useful life of a filter element by providing a visible level of fluid in the display corresponding to the remaining useful life. The fluid level is adjusted by a valve responsive to a pressure differential across the filter element. An increasing pressure differential produces an increased fluid level in the display. The display may be provided with markings indicating that a particular fluid level in the display corresponds to the need to change a filter cartridge containing the filter element.

摘要： A filter assembly employs radially inwardly and outwardly displaced portions of a peripheral roll seam on the cartridge as components of a cartridge compatibility matrix. A base defines an axial entrance to a fixed retainer that is complementary to the compatibility matrix of the cartridge roll seam. Axial slots accommodate the outwardly displaced portions of the roll seam while inward protrusions correspond to the location and inward displacement of the inwardly displaced segments of the roll seam. Incompatible filter cartridges are prevented from axial reception into the base. The number, configuration and location of inwardly and outwardly displaced portions of the roll seam may be varied to provide a variety of unique compatibility matrices.

摘要： A molded base module for a filter assembly includes a header portion that defines a receiving cavity for a replaceable cartridge and may include integral inlet and outlet structures for communicating with the received filtered cartridge. The header portion includes an integrally formed retainer having a retaining channel for receiving tabs projecting from the cartridge, thereby retaining the cartridge to the module. The retaining channel is defined by a retaining lip and axially spaced shoulder connected by a side wall. In an illustrated embodiment, the retaining lip includes a plurality of angularly spaced axial slots and the side wall includes ramp-like projections which mate with correspondingly shaped tabs projecting from the cartridge.

摘要： A fuel filter assembly employs a hand primer and a disposable filter cartridge mounted to a filter base. The filter cartridge and filter base define a fuel flow path through the filter assembly. The filter base includes a sump for receiving fuel that has traversed the filter element. The hand primer includes a deformable member composed of an elastomeric material that cooperates with a base plate to define a cavity. The base plate is disposed intermediate the deformable member and the base sump to separate the cavity from the fuel flow path. The base plate has a plurality of orifices to selectively provide fluid communication between the cavity and the sump. A discharge passage in fluid communication with cavity provides means for discharging air from the fuel filter assembly.
