<p>A twist-on renewable filter for attachment to a distribution head assembly (200). The filter housing is fabricated from components (150, 160) that are made of a polymeric material that are fused together to form the one-piece hollow housing. A filter media (140) assembly is rigidly bonded at both ends within the housing. The renewable filter can be removed and cleaned, for example, by reverse flushing the filter with a cleaning solution. A bypass valve (250) is provided within the filter and functions to allow sufficient fluid to bypass the filter media when the filter media (140) has become contaminated and will not permit the full volume of the normal oil stream to be filtered. The bypass valve (250) has the capacity to permit full volume of the normal oil stream to bypass the filter media when necessary, for example, during a cold start.</p> |
