Abstract
A filter end cap interference fit structure between the internal wall of a closed end pressure vessel and the outer circumference of an end cap for centering and maintaining a filter element in position internally of the pressure vessel. The structure is arranged so as to take up and account for any differences in manufacturing tolerances of the internal parts which could destroy the proper working relationship thereof. The internal parts are solidly secured between the closed dome end of the pressure vessel and the support mounting plate of the vessel to securely hold a filter element therebetween while assuring take-up of manufacturing tolerances.
