A valve arrangement has a valve housing with an inlet and an outlet and a flow regulator including a porous body that is displaceable in the valve housing between the inlet and the outlet. The porous body blocks flow between the inlet and the outlet except for flow through the porous body. The displacement of the porous body between the inlet and the outlet proportionally varies a size of an outer surface of the porous body that is exposed to the outlet, thereby regulating fluid flow between the inlet and the outlet.
