ADDITIVE DISPERSING FILTER AND METHOD

摘要

A method for dispersing an additive from an additive cartridge disposed in a housing of an oil filter is provided herein, the method includes using stagnation pressure to disperse the additive from the additive cartridge; and regulating a flow rate of the additive from the additive cartridge by restricting an inlet opening of an outlet tube of the additive cartridge. Also provide herein is an additive cartridge for dispersing an additive within a filter housing, the additive cartridge having a housing defining a receiving area for receipt of the additive; a fluid inlet path through a wall of the housing, the fluid inlet path providing a means for increasing a pressure within the receiving area, the fluid inlet path having an inlet opening disposed adjacent to an outer wall portion of the housing; and a fluid outlet path through the wall of the housing, the fluid outlet path providing a means for dispersing the additive from the receiving area when the pressure within the receiving area exceeds a predetermined value, the fluid outlet path having an outlet opening disposed adjacent to the outer wall portion of the housing, the outlet opening being covered by a shroud configured to deflect fluid flowing in a first direction away from the outlet opening and the inlet opening of the fluid inlet path is positioned to receive fluid flowing in the first direction; and fluid flow of the additive through the fluid outlet path is controlled by varying an inlet opening of the fluid outlet path.
