ABSTRACT:
A valve for dividing a fluid flow at an inlet port subject to variable flow volume into two fluid flows at first and second outlet ports having a substantially constant ratio of flow volumes, including first and second flow passages from the inlet port to the first and second outlet ports. Each flow passage includes a variable orifice the openings of which are varied by fluid pressures proportional to the fluid pressure acting on opposite ends of a spool valve. A normally closed valve is provided for permitting an increase in fluid flow through the first outlet port when the inlet fluid flow exceeds a predetermined pressure.
