Abstract: A filter assembly includes housing enclosing a replaceable filter element. A support core is provided in the housing, and includes an extension and locking assembly. The element includes a ring of filtration media with a pair of end caps. The first end cap includes a central opening to receive the support core. The extension and locking assembly prevents the cover of the housing from being attached to the housing body without a proper filter element installed. The extension and locking assembly includes a bypass member and a locking member, which are in locking engagement when an element is absent in the housing. The second end cap includes internal protrusions which engage the locking member when the filter element is installed to disengage the bypass member from the support core, and allow the element to be inserted and the cover to be installed.

Abstract: A filter element removably located in a housing having a central valve structure. The element has an end cap with a valve actuating portion. The valve actuating portion includes a cylindrical portion and an annular base projecting radially inward from the cylindrical portion. The valve actuating portion includes a plurality of thin, flat keys spaced around the annular base and projecting radially inward from the cylindrical portion and axially outward from the base. The keys engage the valve structure in the housing when the element is installed, and open up a flow passage through the housing.

Abstract: A fuel filter includes mating housing portions defining an interior cavity. A pipe in the housing includes a central flow passage with an opening along the length of the pipe, and an exterior groove. A latch device with discrete fingers closely surrounds the pipe and is engageable with the groove to prevent the latch device (68) from moving axially along the pipe. The latch device has an annular sleeve, radially-outwardly spaced from the fingers. A moveable valve device surrounds the pipe and has a valve sleeve normally covering the opening in the pipe. An annular base on the sleeve includes radially projecting tabs defining a plurality of slots. A filter element is removeably located in the housing and has an end cap with a valve actuating portion. The valve actuating portion includes a cylindrical portion and an annular base projecting radially inward from the cylindrical portion. The valve actuating portion includes a plurality of thin, flat keys spaced around the annular base and projecting radially inward from the cylindrical portion and axially outward from the base. The keys have first portions which project through the slots in the valve device and engage the sleeve of the latch device to unlock the latch device from the pipe, and second portions which engage the base of the valve device and move the valve device to uncover the opening in the pipe, when the filter element is inserted into the housing.
