ABSTRACT:
A flow prioritizing system includes a regulating valve and a flow prioritizing valve. The regulating valve receives a first portion of the fluid supplied from a fuel supply pump, and is responsive to a control pressure to selectively allow or prohibit flow to secondary loads. The flow prioritizing control valve is responsive to fluid pressure representative of delivery pump discharge pressure to control the control pressure to which the regulating valve is responsive.
