Abstract
A manually actuated dispensing gun can deliver different fluids to be mixed. The gun has a body assembly with first and second valves. A lever arm manually actuates the valves. A cap has first and second fluid inlets that are coupled to respective controlled fluid outlets of the valves. The cap has a duct that opens into and runs from a first inlet to a first cap outlet, and another duct that opens into and runs from the second inlet to a second cap outlet without opening into the other duct. One of the ducts has a larger cross-section flow area along its entire length than the other. Other embodiments are also described and claimed.
Claims24
A fluid dispensing apparatus comprising:
- a cap with first and second inlets to receive separate, metered flows of fluid, the cap having a first duct that directs flow from the first inlet to a first outlet, and a second duct that directs flow from the second inlet to a second outlet without communicating with the first duct, wherein the first duct has a larger cross-section flow area than the second duct;
- a body assembly having first and second valves that feed first and second outlets positioned on a front face of the assembly and to which the first and second inlets of the cap, respectively, are coupled;
- and
- a removable plate to be positioned between the front face of the body assembly and the cap and on which first and second valve seats for the first and second valves, respectively, are formed.
A fluid metering and dispensing system, comprising:
- a metering mechanism to provide metered flows of first and second fluids through first and second outlets, respectively, the first fluid being more viscous than the second fluid;
- and
- a plurality of caps each with first and second inlets, each cap having a first duct that directs flow from the first inlet to a first outlet, and a second duct that directs flow from the second inlet to a second outlet without communicating with the first duct, wherein the first duct has a larger cross-section flow area than the second duct, wherein a cross-section flow area relationship between the first and second ducts of each cap is different, each cap being specified for use with different types of said first and second fluids having different viscosities, to obtain better mixing of said first and second fluids;
- and
- a fluid dispensing apparatus with a body assembly having first and second valves that are coupled to the first and second outlets of the metering mechanism and that feed first and second outlets positioned on a front face of the assembly to which first and second inlets of a selected one of the plurality of caps, respectively, are coupled and a removable plate to be positioned between the front face of the body assembly and the selected cap and on which first and second valve seats for the first and second valves, respectively, are formed.
