Renewable filter
摘要:
A twist-on renewable filter comprising a one-piece hollow housing, made of polymeric material having a threaded adapter for attachment to a distribution head assembly. The filter housing is fabricated from components that are made of a polymeric material that are fused together to form the one-piece hollow housing. A filter media assembly is rigidly bonded at both ends within the housing. The renewable filter has an infinite life and 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 that is designed to provide full closure for an infinite life. The bypass valve 250 is fully located within the one-piece hollow housing such that it cannot be disabled or tampered with. The bypass valve 250 functions to allow sufficient fluid to bypass the filter media when the filter media 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 the full volume of the normal oil stream to bypass the filter media when necessary, for example, during a cold start.
