Abstract
An oil system, has: a pump driving an oil flow in an oil conduit, the pump having an outlet pump pressure; a heat exchanger providing heat exchange between the oil flow and one or more fluid; a component downstream of the heat exchanger, the component having a maximum oil pressure requirement and a minimum oil pressure requirement; and a flow restrictor in fluid flow communication with the oil conduit, the flow restrictor having an orifice sized to provide a restrictor pressure differential across the flow restrictor, the restrictor pressure differential being equal to at least the outlet pump pressure minus pressure differentials through the heat exchanger and the oil conduit from an outlet of the pump to the component minus the maximum oil pressure requirement, and at most the outlet pump pressure minus the pressure differentials through the heat exchanger and the oil conduit minus the minimum oil pressure requirement.
