Abstract
A dual outlet fluid valve capable of obtaining a closed state operation mode for both outlet ports, a low flow operation mode for either operating port either individually or combined, or a high flow operation mode for either outlet port individually or combined such that at least five distinct operating conditions can be obtained. The fluid valve is not charged with fuel when in a closed position.
Claims19
A fluid valve assembly, comprising:
- a valve body (12) including a main cavity (20), said valve body having:
- an inlet passage (26, 26a) in communication with said main cavity, a pair of outlet passages (28, 30) in communication with said main cavity, a primary outlet port (16) in communication with said main cavity, and a secondary outlet port (18) in communication with each of said pair of outlet passages (28, 30);
- a plug member (22) rotatably disposed in said main cavity, said plug member having:
- a wall (52) defining a bore (54) extending axially from a first end (56) of said plug member, said wall having a thickness extending radially from an interior surface (52b) to an exterior surface (52a), a dual flow aperture (78) extending radially from said bore through said wall and operable for selectively providing fluid communication between said primary outlet port (16) and said secondary outlet port (18), and a slot (74) extending partially inward from said exterior surface (52a) of said wall (52), said slot axially aligned to provide selective fluid communication between said inlet (26a) and one of said pair of outlet passages (28).
