  • Patent number: 4969994
    Abstract: A filter arrangement is provided which includes preferred fluid sealing between a top plate thereof and a housing. Generally, the filter arrangement includes a housing, a top plate and an internal filter. The top plate encloses an end of the housing, retaining the filter therein and directing fluid flow appropriately across the filter. Engagement between the housing and the top plate is such that a gasket may be used to provide sealing of an operable combination of the filter arrangement with an associated filter head, with respect to flow space between the housing and top plate by means of a simple gasket position externally of the filter arrangement. Several embodiments have shown, and in at least one the housing edge terminates in a groove in the top plate, in which a sealing gasket may be positioned. Positive engagement between the top plate and the housing is provided by a variety of projection arrangements.
