ABSTRACT:
A fluid supply system provides hydraulic fluid to a series combination of an automotive fan motor and a power steering unit. There is a bypass line around the fan motor for prioritizing the operation of the power steering unit. A normally closed pressure sequencing valve opens the bypass line when the pressure across the overall series combination exceeds a predetermined limit. Optional second and third bypass lines are disclosed for respectively bypassing either the power steering unit or the fan motor in case of abnormal conditions therein.
