Filter with Inner-Sealed Pulsation Dampener

摘要

A filter and replacement filter cartridge is provided with a pulsation dampener mounted and sealed to the filter cartridge basket at an inner diameter thereof. The pulsation dampener is captive to the basket such that removal of the basket from the filter housing canister removes all of the basket, filter media, and pulsation dampener as a single unit without separate, loose parts thereof. An axial extension section of the basket facilitates gripping and removal, and maintains a fully seated installed filter position. Sealing is provided without a section of the pulsation dampener interposed between the filter housing canister and lid.
