Abstract: A fuel filter assembly (10) includes a housing (12) with an internal chamber (14) and inlet and outlet (18, 22). The chamber is bounded by an annular wall (16) and has an opening (30) at an upper end thereof. An element (26) is accepted in the chamber. The element includes a manually engagable cap portion (28) for closing the opening, and a disk shaped member (46). The disk shaped member has a deformable lip portion (50) for engaging the annular wall, and for fluidly separating an aperture (24) in connection with the outlet fitting, from an aperture (20) in fluid communication with the inlet fitting. A media body (54) of filter media (56) removes impurities from liquid flowing therethrough. Fuel flows from the inlet to the chamber and then through the media. From an interior area (60) of the media body, the fuel passes through a passage (62) into an intermediate area (52) and out the outlet. An element change may be accomplished without spilling or contacting the fuel, and without contaminants in the chamber reaching the aperture in fluid communication with outlet.

Abstract: A fuel filter comprises a head (10, 96) having an inlet (14, 100) and an outlet (16,102). The head has a pumping portion (18, 104) which includes a vertically extending stepped bore (46, 120) having movable bodies (86, 88; 132, 140) therein. The fluid area between the bodies (54, 126) is connected to a variable volume area (77, 160). The head is connected to an element (98, 266) by a nipple portion (186) which has a valve element (196) therein. An actuating projection (222, 272) is engagable with said valve element to open flow through said nipple portion when the correct element is attached thereto. The failure of the nipple portion to sufficiently extend in the element, which occurs when an improper element is attached, prevents flow through the nipple portion and renders the filter inoperable. The actuating projection is further supported on a central portion (220, 276) which prevents connection to a nipple portion that extends too far into the element. As a result, only the proper element may be mounted to the head.

Abstract translation: 燃料过滤器包括具有入口（14,100）和出口（16,102）的头部（10,96）。 头部具有泵送部分（18,104），该部分包括其中具有可移动体（86,88; 132,140）的垂直延伸的阶梯孔（46,120）。 主体（54,126）之间的流体区域连接到可变容积区域（77,160）。 头部通过其中具有阀元件（196）的接头部分（186）连接到元件（98,266）。 当正确的元件附接到其上时，致动突起（222,272）可与所述阀元件接合以打开通过所述接头部分的流动。 乳头部分在不适当的元件附接时发生的元件中充分延伸的故障防止流过奶嘴部分并使过滤器不可操作。 致动凸起进一步支撑在中心部分（220,276）上，该中心部分防止连接到延伸到元件太远的接头部分。 结果，只有适当的元件可以安装到头部。

Abstract: A filter system comprising a tank and a filter assembly removably mounted therein. The filter assembly includes a plurality of filter tubes in fluid communication with a plenum chamber on the bottom thereof. The plenum chamber is open on its bottom, and rests on the bottom of the filter tank. Suitable seals maintain the fluid integrity of the plenum chamber against the bottom of the tank. The filtrate leaves the plenum chamber through an outlet port in the bottom of the tank.The inlet port is also in the bottom of the tank, and the fluid to be filtered passes upwardly through a channel formed in the center of the plenum chamber. The top of the tank is sealed by a U-shaped gasket, with the cover of the tank resting on the gasket. No auxiliary flanges are needed to provide a top seal. The cover of the tank is raised by a lifting mechanism, and is rotatable away from the top of the tank to permit access to the tank. When the cover is to be returned to its closing position, a keying mechanism automatically seats the cover in the proper position.

Abstract: Base and cover members of a vacuum filter having walls each terminating with an annular bead are sealably joined together by a flexible annular joint. The joint has a median part defining, with an inner flange and a first rounded outer lip, an annular cavity in which the bead of the base member is tightly gripped. A second thinner and more flexible rounded outer lip fits over the bead of the cover member and has a terminal skirt portion which resiliently bears against its wall. The cover member can be removed by outwardly bending the second lip while the joint remains fitted on the base member.
