Abstract: A filter assembly includes a housing with a central standpipe, and cover for enclosing a filter element. The filter element includes a ring of filtration media and first and second end caps. A vent orifice is formed in the first end cap into the central cavity of the media ring. A support core is disposed centrally in the media ring and extends between the first and second end caps. The core includes a separate and independent fluid channel extending from the first end cap that is fluidly connected with the vent orifice, to the second end cap. The second end cap has a central opening, and an annular sealing device bounding the opening which receives and seals to the standpipe and includes through-passages fluidly interconnecting the fluid channel in the core with flow opening(s) along the standpipe or in the lower end of the housing to a drain port.

Abstract: A valve (20) has a valve housing (22) with a central passage (28) extending axially through the valve housing (22). Aperture (40) in the valve housing connect a second passage (38) to the central passage (28) to extend through the valve housing. A poppet valve member (24) is configured for sealing engagement of the central passage (28). The valve member (24) is urged into sealing engagement with the central passage (28) by internal pressure in a container (36) on which the valve (20) is provided. The valve member (24) and the valve housing (22) are configured so that the valve member (24) will drop away from sealing the central passage (28) when the pressure in the container (36) is insufficient to hold the valve member (24) in sealing position against the central passage (28) to leave the valve (20) in a permanently open state. An annular valve member (26) seals the second passage (38 ) in the same manner.
