- a piston is mounted in a sleeve in the housing beyond the nozzle and is provided with a sealing means at one end thereof.
- Spring means normally bias the piston against the outlet end of the nozzle so that the sealing means normally closes the outlet end.
- a second outer conduit concentric with the first conduit is connected to the entrance end of the valve housing for supplying a second fluid under pressure thereto.
- a first fluid passageway is formed between the nozzle and the valve housing to permit the second fluid to initially pass through the valve housing past the nozzle.
- a second fluid passage is provided around the outside of the piston which is normally closed but which is opened when the piston moves away from the nozzle with the flow of the second fluid.
- the movement of the piston away opens the nozzle outlet and permits the first fluid to exit from the nozzle and mix with the second fluid whereby the mixture of the fluids then passes through the second passageway to be discharged through the exit end of the valve housing.
- the first fluid passing through the nozzle has a greater fluid pressure than that of the second fluid passing around the nozzle so that the first fluid upon leaving the nozzle outlet end flows outwardly in the valve housing to mix with the second fluid passing around the outside of the nozzle to facilitate mixing the two fluids.
- This invention relates generally to a fluid valve and mixing assembly adapted to dispense and mix at least two different fluids and more particularly to such an assembly employing a spring loaded piston movable in a guide sleeve to open and close a fluid nozzle to facilitate the mixing of a stream of air and a catalyst.
- Another feature of the present invention is to avoid the disadvantages of the known fluid mixing devices enumerated above.

- a second fluid under pressure such as air
- the second fluid under pressure is supplied to the chamber 25 through outer conduit 14.
- the second fluid which may be air under pressure, travels around the body of fluid nozzle 40 on the outside of chamber 25, through the passageways 50 formed between the webs 49 of the fluid'nozzle 40 and then through the passageways 69 formed between the rectangular portion 66 0f the piston 65 and the inside of the cylindrical-sleeve 60 as shown by arrows 57.
- the second fluid contacts the inner end of the circular end portion 67 of the piston 65, thus moving the piston towards the exit end 39 of chamber 25.
- the sealing circular end portion 67 travels beyond the point where the ports or slots 62 of the sleeve are positioned.
- the fluid passing around the outside of the rectangular portion 66 of the piston exits through the ports 62 into the end portion 37 of chamber 25 and then out through the central passageway 27 of the exit end 39.
- the orifice 53 of the fluid nozzle 40 is opened to permit the first fluid or catalyst supplied through inner conduit 13 to exit through the orifice 53 into the interior of the sleeve 60 as shown by arrows 58. If the first fluid or catalyst is supplied at a pressure greater than the second fluid flowing around the outside of the nozzle, the first fluid will flow outwardly to the periphery of the inside of the sleeve 60 and mix with the second fluid. From this point, the mixture is moved through the passageways 69, ports 62 and the exit end 39 of the assembly 10.
- the first fluid supplied to the inside of the nozzle 40 be at a greater pressure than the second fluid supplied to the chamber 25.
- the energy stored in the spring 73 due to the initial displacement of the piston 65 is released and the piston 65 returns to its normally closed position with the sealing member 71 biased against the orifice 53 of the nozzle 40, thus terminating fluid flow from the orifice.
- the fluid valve and mixing assembly permits two fluids, such as air and a catalyst, to be maintained separately and subsequently mixed for further usage.
- the spring loaded piston 65 provides a convenient means for preventing fluid flow through the assembly 10 until a second fluid under pressure is supplied to the chamber 25 of the valve and mixing assembly 10.
- the means of the present invention provides a convenient means for mixing two separate fluids. It is simply necessary to provide the first fluid supplied to the interior of the nozzle at a greater pressure than the second fluid supplied to the chamber so that upon opening the orifree 53 of the fluid nozzle 40, the first fluid flows outwardly to be mixed with the second fluid passing through the chamber of the means. The mixing of the two fluids thus can be accomplished with a minimum of air pressure.
- polyester resins including, but not limited .to, polyester resins, epoxy resins, urethane resins, silicone rubber and the like.
- the plural component material is converted, at ambient atmospheric temperature, from a liquid phase to a solid phase by the addition of an appropriate catalyst or curing agent.
