Abstract
Abstract A fluid metering system for assuring a substantially constant supply ratio of a plurality of components of a multi-component mixture during both steady-state and start-up conditions. The system includes a plurality of inlet valves, one for each of the fluids comprising a portion of the mixture, and also includes means for simultaneously actuating each of the inlet valves from a no-flow to a full-flow position. The system further includes means for adjusting the relative angular positions of the several valve members of each of the valves in order to permit variations in initial flow starting times between the valves and thereby compensate for pressure or viscosity differences between the several components of the mixture to maintain a substantially constant ratio of the components.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
107 words
A fluid metering system for assuring a substantially constant supply ratio of a plurality of components of a multi-component mixture during both steady-state and start-up conditions, said system comprising: a. a plurality of valves, one for each fluid constituting a substantial portion of the mixture; b. means for simultaneously actuating each of said valves from a no-flow to a full-flow position at the outlet of each of said valves; c. means for adjusting the relative angular positions of the valve members of each of said valves to permit variations in initial flow rates between said valves; and d. a receiver into which said valves discharge said components.
Claim 2
Dependent Claim
107 words
A fluid metering system for assuring a substantially constant supply ratio of a plurality of components of a multi-component mixture during both steady-state and start-up conditions, said system comprising: a. a plurality of valves, one for each fluid constituting a substantial portion of the mixture; b. means for simultaneously actuating each of said valves from a no-flow to a full-flow position at the outlet of each of said valves; c. means for adjusting the relative angular positions of the valve members of each of said valves to permit variations in initial flow rates between said valves; and d. a receiver into which said valves discharge said components.
Claim 3
Dependent Claim
13 words
The fluid metering system of claim 1 wherein said valves are three-way valves.
Claim 4
Dependent Claim
33 words
The fluid metering system of claim 1 wherein each of the valves is so arranged that all valve members rotate in the same direction in going from a no-flow to a full-flow condition.
Claim 5
Dependent Claim
21 words
The fluid metering system of claim 1 wherein orifices are positioned at the outlets of at least one of said valves.
Claim 6
Dependent Claim
37 words
The fluid metering system of claim 1 wherein the position of the valve members of each of said valves is actuated by means of a drive gear connected to a rotatable shaft attached to said valve members.
Claim 7
Dependent Claim
25 words
The fluid metering system of claim 5 wherein each of said drive gears is actuated by a pinion centrally positioned with respect to said valves.
Claim 8
Dependent Claim
15 words
The fluid metering system of claim 6 wherein said drive gears are of equal size.
Claim 9
Dependent Claim
32 words
The fluid metering system of claim 5 wherein each of said drive gears is releasably and adjustably connected to a cooperating drive member which is drivingly connected to its respective rotatable shaft.
Claim 10
Dependent Claim
28 words
The fluid metering system of claim 8 therein each of said drive gears can be circularly adjusted and fixed in position with respect to its cooperating drive member.
Claim 11
Dependent Claim
45 words
The fluid metering system of claim 9 wherein each of said drive gears is contiguous with a major portion of its cooperating drive member and includes a pair of spaced arcuate slots through which said drive gear can be bolted to its respective drive member.
Claim 12
Dependent Claim
29 words
The fluid metering system of claim 5 wherein a pair of said drive gears is actuated by unitary rack which intermeshes therewith and is carried by a supporting means.
