Abstract
A filter assembly includes a manifold having a fluid inlet and a fluid outlet, a filter housing having a filter medium provided therein, the filter medium defining an inner filter chamber and defining an outer filter chamber between the filter medium and the filter housing, the filter housing being removably attached to the manifold so as to provide a fluid flow path from the inlet into the inner filter chamber, through the filter medium into the outer chamber and out of the outlet. The filter assembly further includes a valve assembly mounted inside the manifold that includes a valve piston and a valve spring arranged in engagement with the valve piston to bias the valve piston into a first position and to compress, in response to a pressure differential across the valve piston exceeding the spring force, to move the valve piston to a second position.
