Abstract
A flow divider (20) is located between a first fuel return line (18), leading from an engine to the flow divider (20), a second fuel return line (22) leading from a first flow divider outlet (46) to a first tank (A), and a third fuel return conduit (24) leading from a second flow divider outlet (48) to a second tank (B). Returned fuel enters the flow divider inlet (34) and flows into an inlet chamber (54). The fuel flows from the inlet chamber (54) through first and second orifices (50, 52). The first orifice (50) is in flow alignment with a first outlet (42). The second orifice (52) is in flow alignment with a second outlet (44). A first closure member (86) is located in a first outlet opening (104) and a second closure member (88) is located in a second outlet opening (106). The closure members (86, 88) are connected to a common member (90). A spring (82) normally biases the closure members (86, 88) towards the orifices (50, 52). Fuel pressure in the inlet chamber (54) exerts forces on the closure members (86, 88), moving them away from the orifices (50, 52) against the force of the spring (82). The closure members (86, 88) will move substantially equal amounts even if forces act…
