Abstract

A fluid composition dispensing system employs a pair of bulk supplies of fluid components which communicate through air-actuated pumps to measurement and dispensing reservoirs. Each of the reservoirs has an associated float switch which is operative to inhibit operation of the associated pump when the reservoir is filled with a desired quantity of fluid component. A dispensing valve assembly is interposed between the two reservoirs to allow for dispensing from the reservoir at predetermined dispensing rates. A mechanical valve assembly has a linkage which is configured to allow the slower flowing fluid to pass through a larger valve orifice such that the dispensing rates of the two fluids are the same.

Claims

1. A fluid composition dispensing system, comprising:

a plurality of bulk supplies of fluid components of a fluid composition;

a plurality of measuring and dispensing reservoirs in communication with said bulk supplies;

first means interposed between said bulk supplies and said measuring and dispensing reservoirs for controlling passage of measured volumes of said fluid components into said measuring and dispensing reservoirs;

second means interconnecting said plurality of measuring and dispensing reservoirs for commonly dispensing said fluid components;

wherein said second means comprises a dispensing conduit passing from each of said measuring and dispensing reservoirs to a dispensing nozzle, and a dispensing valve interposed in each said conduit, said dispensing valves are manually actuated by interconnection with a single handle, and a dispensing rate associated with each said dispensing valve is a function of a flow rate of an associated fluid component and the volume percentage of such component in said fluid consumption; and

a linkage interposed between said valves and said handle, said linkage having an actuating arm engaging each valve, each such actuating arm having a length determinative of an amount an associated valve is opened when said handle is moved to an open position, said lengths of said actuating arm being a function of said flow rate and volume of an associated fluid component being dispensed.

2. The fluid composition dispensing system according to claim 1, wherein said actuating arms connect to associated valves at fixed pivots and to a transverse link at moving pivots.

3. The fluid composition dispensing system according to claim 1, wherein said first means comprises a level sensing switch in each said measuring and dispensing reservoir, and a valve interposed between said bulk supplies and associated measuring and dispensing reservoirs.

4. The fluid composition dispensing system according to claim 3, wherein said first means further comprises a pump interposed between each said bulk supply and said measuring and dispensing reservoirs, said valves interconnecting said pumps and actuating and deactivating said pumps under control of said level sensing switches.

5. The fluid composition dispensing system according to claim 4, wherein said pumps are air driven pumps and wherein said valves are interposed between said pumps and a source of air pressure.

6. The fluid composition dispensing system according to claim 4, wherein said second means interconnects with said level sensing switches and disables said switches when said fluid components are being dispensed.
