Abstract: A filter assembly includes housing and a filter device disposed within the housing to define a circumferential cavity therebetween. The filter assembly further includes a bypass valve having a housing wall, multiple inlets and an outlet formed on the housing wall, and a valve member. A first end of the valve member is coupled to a valve seat and a second end of the valve member engages with the outlet of the bypass valve. The valve member is displaced from a first position to a second position when pressure of fluid in the circumferential cavity is greater than a biasing force of a spring, and wherein the valve member engages with the outlet port of the bypass valve against the biasing force of the spring in the first position and the valve member allows the fluid to flow into the hollow center tube in the second position.
