Abstract
Abstract A valve body having an inlet opening and two outlet openings and an intermediate chamber. Two spools are slidably disposed in the chamber and have fluid passageways which move relative to the valve body outlet openings for varying the flow through the outlet openings. The spools are spring-biased and the spring pressure is adjustable. Also, a spool control member is disposed in the body for adjustably setting the limit position of the spools relative to their sliding movement for limitly setting the amount of flow through the valve.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
236 words
A flow divider valve comprising a valve body having a fluid inlet and two fluid outlets and an intermediate chamber connected to said inlet and said outlets, two spools slidably disposed in said chamber and being movable over respective ones of said outlets, said spools each having a fluid passageway in fluid-flow communication with a respective one of said outlets for controlling flow of fluid from said inlet to said outlets, said spools being unconnected relative to each other and free of each other and in snug sliding engagement with said chamber and with each of said spools having its said fluid passageway disposed to register in direct flow with a respective one of said outlets and being slidable thereover for varying the size of the flow passageway through said fluid passageways and thereby alter the quantity of flow to said outlets, said spools being independently slidable in said chamber and directly over each respective said outlet according to the magnitude of the fluid pressure at each said outlet, means operative on said spools for influencing the respective position of registry of each of said fluid passageways of said spools relative to said outlets, and a member adjacent said inlet and in the path of flow through said inlet and movable toward and away from said inlet and in accordance with the sliding movement of said spools for altering the flow of fluid through said inlet.
Claim 2
Dependent Claim
236 words
A flow divider valve comprising a valve body having a fluid inlet and two fluid outlets and an intermediate chamber connected to said inlet and said outlets, two spools slidably disposed in said chamber and being movable over respective ones of said outlets, said spools each having a fluid passageway in fluid-flow communication with a respective one of said outlets for controlling flow of fluid from said inlet to said outlets, said spools being unconnected relative to each other and free of each other and in snug sliding engagement with said chamber and with each of said spools having its said fluid passageway disposed to register in direct flow with a respective one of said outlets and being slidable thereover for varying the size of the flow passageway through said fluid passageways and thereby alter the quantity of flow to said outlets, said spools being independently slidable in said chamber and directly over each respective said outlet according to the magnitude of the fluid pressure at each said outlet, means operative on said spools for influencing the respective position of registry of each of said fluid passageways of said spools relative to said outlets, and a member adjacent said inlet and in the path of flow through said inlet and movable toward and away from said inlet and in accordance with the sliding movement of said spools for altering the flow of fluid through said inlet.
Claim 3
Dependent Claim
48 words
The flow divider valve as claimed in claim 1, wherein said member is in contact with said spools, and an adjuster operable on said member for positioning said member relative to said spools for selectively spacing said spools apart to position said spool passageways relative to said outlets.
Claim 4
Dependent Claim
43 words
The flow divider valve as claimed in claim 1, wherein said spools each have a fluid-pressure surface faced in the direction of said fluid inlet, said means is spring means disposed to yieldingly urge said spools toward each other and toward said inlet.
Claim 5
Dependent Claim
27 words
The flow divider valve as claimed in claim 3, wherein said member is a sphere nestable with said inlet and is also in contact with said surfaces.
Claim 6
Dependent Claim
57 words
The flow divider valve as claimed in claim 4, including an adjustment member movably mounted on said valve body and in operative contact with said sphere for displacing said sphere across the path of movement of said spools and thereby determine the spacing between said spools and the positions of said spool passageways relative to said outlets.
Claim 7
Dependent Claim
28 words
The flow divider valve as claimed in claim 3, wherein said fluid-pressure surfaces are oblique relative to the path of sliding movement of said spools in said chamber.
Claim 8
Dependent Claim
33 words
The flow divider valve as claimed in claim 3, wherein said spring means includes two springs oppositely disposed in contact with respective ones of said spools for urging said spools toward each other.
Claim 9
Dependent Claim
31 words
The flow divider valve as claimed in claim 7, and including adjustment means operative on said spring means for urging said spools toward each other in accordance with selected adjusted forces.
