    摘要： A filter having improved means of positive shutoff employs a rigid tubular fuel pervious core surrounded by flexible filter media that intercepts and resists the passage of particulate matter and water. A tubular retention sleeve is positioned within and in dosed communication with the tubular core at one end thereof, the retention sleeve having an integral ball retention portion of reduced internal diameter. An end cap is sacred to the other end of the tubular core member and has an annular sealing surface surrounding a flow passageway opening therethrough. A ball is normally positioned within the retention sleeve and in the engagement with the circumferential ball retention seat. When the flexible filter media has absorbed a sufficient quantity of water the pressure differential across the ball forces it to pass through the retention seat and to lodge against the sealing surface of the end cap, thereby closing further flow through the filter.

    摘要翻译： 具有改进的积极关闭装置的过滤器采用刚性的管状燃料透过芯，其被柔性过滤介质包围，该过滤介质拦截并抵抗颗粒状物质和水的通过。 管状保持套筒位于管状芯部的一端内并与其一体地连通，保持套筒具有内径减小的整体球保持部分。 端盖对于管状芯构件的另一端是神圣的，并且具有围绕通过其的流动通道开口的环形密封表面。 球通常定位在保持套筒内并与圆周球保持座接合。 当柔性过滤介质已经吸收了足够量的水时，跨越球的压力迫使其通过保持座并且抵靠端帽的密封表面，从而进一步流过过滤器。

    摘要： A fuel filter with improved means of preventing water and particulate contaminant from passing therethrough includes a cannister 10, a plate 16 secured to the cannister open end 12 having a central fluid outlet 18 and fluid inlet openings 20 spaced from the fluid outlet, a rigid tubular fluid pervious member 22 within the cannister having one end in sealed communication with the plate fluid outlet opening, a flexible filter medium 36 surrounding the outer surface of the tubular member through which fuel readily passes but which resists the passage of particulate matter and water, a first deformable washer 30 having an opening 30A therethrough secured to the end of the tubular member opposite that attached to the plate, a ball 40 within the cannister and normally in engagement with the first washer, the ball having a diameter slightly greather than the internal diameter of the washer, and an annular seal 26 between the plate fluid outlet opening and the first end of the tubular member, a second deformable washer member 38 supported concentrically of and adjacent to the annular seal, the first washer being deformable to permit the ball to pass through when a predetermined fluid pressure drop develops across the flexible filter media, the ball thereby engaging and passing, the second washer to engage the seal to block further fluid flow through the filter, the second washer serving to retain the ball adjacent the seal even in absence of fluid pressure.

A tubular retention sleeve is positioned within and in dosed communication with the tubular core at one end thereof, the retention sleeve having an integral ball retention portion of reduced internal diameter.
