Abstract
A fluid filtering device includes a housing having an interior chamber with an open top and an inlet and outlet open to the chamber. An annular seat is secured to the housing within the chamber in a position spaced downwardly from the open top so that the seat protrudes inwardly into the chamber. A filter element is removably insertable into the chamber through its open top and to a filtering postion in which the filter element is positioned between the housing inlet and outlet. The filter element includes an outwardly flanged portion which abuts against the seat when the filter element is in its filtering position. A cover is detachably secured over the open top of a housing and a spring member is secured at one end to the filter element to extend upwardly to abut against the cover and secure the filter element in position against any loss of seal with respect to the housing during operation of the filtering device. A handle is mounted to the filter element to facilitate removal and insertion of the filter element.
