End cap relief valve mechanism for a filter |
摘要 |
An oil filter includes a housing 14 having an end plate 20 attached to the open end thereof. The end plate 20 includes an outlet opening and inlet openings 22. An anti-drainback valve 49 is provided adjacent the end plate. A filter element having an end cap at each end is positioned within the housing. The end cap 50 remote from the end plate includes a plurality of openings 52 spaced from a closed central portion 51. A spring valve 60 cooperates with the end cap 50 and the interior wall of the housing to alternately allow and disallow oil flow through the end cap openings depending upon the differential pressure across the end cap 50. The spring valve 60 and the end cap 50 can be operationally interengage to provide a relatively flat profile. Depressions 72 (FIG. 5) may be included between the arms 62 of the spring valve to provide a flow path should the spring valve be flattened against the housing during operation of the filter.
