    摘要： A releasable electrical connector having a receptacle component and a plugomponent which can be mated and disconnected by relative rotation between components and can be separated by a straight breakaway force. The receptacle component is provided with bayonet pins that engage semicircular holes in a spring-biased sleeve positioned in the plug component. One end of the spring-biased sleeve is divided into sections and two opposed sections are permanently bent outwardly at an angle sufficiently large so as to clear the bayonet pins on the receptacle component. The semi-circular holes used for locking the bayonet pins are provided in the bent sections and a boss on the interior surface of the plug component compresses the bent sections to lock the bayonet pins in the semi-circular holes. A breakaway force moves the sleeve outwardly from the boss and, when the bent sections clear the boss, the resilient bent sections spring outwardly to release the bayonet pins.

    摘要： A filter cartridge 38 includes a first endcap 41 defining a first open aperture and having at least first and second protrusions extending from a wall along the aperture and into the first open aperture. The first protrusion is spaced from the second protrusion in both a vertical direction and a circumferential direction. The filter cartridge also includes filter media 44 and a second endcap 42. The filter cartridge is mountable in a filter bowl 36 having an inner liner assembly, and the bowl and the inner liner assembly is connectable to a filter head to form a filter system. The filter system can have any one or combination of the following features: a filter lock-out mechanism to ensure that the filter head and the filter bowl are not connectable unless there is a proper filter cartridge installed therein; an automatic drain mechanism to drain the filter bowl of liquid before the filter cartridge is removed from the bowl; and a cartridge retention mechanism, to ensure that the filter cartridge remains with the filter bowl after the filter bowl has been removed from the filter head. Adaptor rings can be utilized in order to test other types of filter elements in the system, when those other types of filter elements do not have the protrusion arrangement. Assemblies, methods of servicing, methods of installing, methods of use, and methods of retaining can be practiced.

    摘要翻译： 过滤筒38包括限定第一开口孔的第一端盖41，并且具有至少第一和第二突出部，该第一和第二突出部沿着孔从壁延伸并进入第一开口孔。 第一突起在垂直方向和圆周方向上与第二突起分隔开。 过滤器滤芯还包括过滤介质44和第二端盖42.滤筒可安装在具有内衬组件的过滤碗36中，并且碗和内衬组件可连接到过滤头以形成过滤系统。 过滤系统可以具有以下特征中的任何一种或组合：过滤器锁定机构，用于确保过滤器头和过滤器碗不可连接，除非其中安装有适当的过滤器滤芯; 一个自动排水机构，在滤筒从碗中取出之前，排出液体滤筒; 以及墨盒保持机构，以确保在过滤器滤芯从过滤器头部移除之后滤芯保持在滤筒上。 当这些其他类型的过滤元件不具有突出布置时，可以使用适配器环​​来测试系统中的其它类型的过滤器元件。 可以实施组装，维修方法，安装方法，使用方法和保持方法。

    摘要： A filter element includes filter media, first and second end caps, a latch arrangement projecting from the first end cap, a tubular neck extending from the first end cap and a valve head oriented within the first end cap aperture constructed and arranged to move between a position sealing the first end cap aperture and exposing the first end cap aperture. A filter assembly includes a filter element, as characterized herein, and including a filter base and a service cover. A method of servicing includes removing an old filter element, operably mounting a new filter element in a filter base including engaging a valve head against a spring member in the filter base, and operably mounting the service cover over the new filter element and filter base.
