摘要： A fluid filter for assembly onto a filter head includes a combination of features such that the assembly of the fluid filter onto the filter head establishes radial flow paths within the fluid filter. The filter head includes an externally threaded outer wall and includes an annular inner wall which defines a flow opening. The inner wall is shaped with a protruding portion and a substantially horizontal bearing surface. The fluid filter includes an enclosing outer shell and a filtering element positioned within the outer shell. A support spring is positioned in the base of the outer shell so that it is axially positioned between the outer shell and the filtering element. An internally threaded nutplate is assembled to the outer shell and threadedly engages the externally-threaded outer wall of the filter head. An inner seal is positioned between the nutplate and the primary filtering element and is designed so as to define a hollow interior. Threaded engagement between the filter head and the nutplate begins the installation procedure. As threaded engagement continues, the protruding portion is inserted into the hollow interior and the bearing surface abuts up against the upper surface of the inner seal. With continued threaded engagement, the bearing surface pushes the inner seal and filtering element axially downward in the direction of the support spring, causing the inner seal to move axially away from the nutplate creating a radial flow path between the inner seal and the nutplate.

摘要： An apparatus for detecting a vehicle having a vapor recovery system having a fuel dispenser configured to deliver fuel to a fuel tank of a vehicle, a vapor recovery system operatively associated with the fuel dispenser having a vapor path for removing fuel vapor expelled from the fuel tank of the vehicle during a fueling operation, and a hydrocarbon vapor sensor associated with the vapor path for sensing the fuel vapors in the vapor path, wherein when the vapor sensor does not sense fuel vapor during the fueling operation, the fuel dispenser determines the vehicle contains an onboard vapor recovery system. Once a vehicle having an onboard vapor recovery system is detected, the vapor recovery system is either shut off or adjusted during the fueling operation to minimize fugitive emissions.

摘要： A seal arrangement for a fluid filter assembly which is constructed and arranged to threadedly mount onto an engine block mounting base includes an inner seal and an outer seal. The fluid filter assembly includes an outer shell, a filtering element located within the outer shell and defining therewith an annular clearance space. The fluid filter assembly further includes a nutplate which is anchored to the outer shell and which includes an internally-threaded center aperture for threaded engagement onto the engine block mounting base. The inner seal is positioned between the nutplate and the filtering element and cooperates with the nutplate in order to provide a plurality of flow paths between the inner seal and the nutplate from the engine mounting base to the annular clearance space. The outer seal is positioned between the engine block mounting base and the nutplate and includes a pair of spaced-apart ribs which provide a sealing interface against the engine block mounting base.

摘要： A threaded fastener which is constructed to be turned in one direction by a square socket drive includes a threaded stem and an integral modified head arranged with four raised projections which are circumferentially spaced. Each of the four raised projections includes a substantially flat wall portion and a curved and inclined ramp portion. The four flat wall portions effectively define a square center region which is compatibly sized to receive a one-half inch square socket drive. Rotation of the square socket drive in a counterclockwise direction causes the sides of the square socket drive to engage the flat wall portions so as to turn the threaded fastener in a counterclockwise direction. Any attempt to rotate the square socket drive in a clockwise direction causes the sides of the square socket drive to ride up along the ramp portions and ride out of engagement with the modified head of the threaded fastener. In a related embodiment of the present invention, the four raised projections have their orientation reversed so that the square socket drive is effective to threadedly advance the fastener when the drive is turned in a clockwise direction. Likewise, in this alternate embodiment, when the square socket drive is turned in a counterclockwise direction, it rides up along the ramp portions and come out of engagement with the modified head. As described, the present invention includes a one directional threaded fastener which is manipulated by a square socket drive.
摘要翻译： 构造成通过方形插座驱动器在一个方向上转动的螺纹紧固件包括螺纹杆和整体改进的头部，该头部布置有四个凸出的凸起，其周向间隔开。 四个凸起突起中的每一个包括基本上平坦的壁部分和弯曲和倾斜的斜坡部分。 四个平壁部分有效地限定了一个正方形的中心区域，该中心区域的尺寸适合接收一个半英寸的方形插座驱动器。 方形插座驱动器沿逆时针方向的旋转使得方形插座驱动器的侧面与平坦的壁部分接合，以沿着逆时针方向转动螺纹紧固件。 任何使方形插座驱动器沿顺时针方向旋转的尝试使得方形插座驱动器的侧面沿着斜坡部分上升，并且与螺纹紧固件的改进的头部脱离接合。 在本发明的一个相关实施例中，四个凸起突起的方向相反，使得当驱动器沿顺时针方向转动时，方形插座驱动器有效地使紧固件螺纹前进。 同样，在该替代实施例中，当方形插座驱动器沿逆时针方向转动时，它沿着斜坡部分上升并与修改的头部脱离接合。 如上所述，本发明包括由方形插座驱动器操纵的单向螺纹紧固件。
