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.
