System, Method, and Apparatus for Mixing and Spraying Resin and Catalyst

1 . A dual input valve comprising:

a valve stem having a first end and a distal end;

a compressed air valve formed on the valve stem between the first end and the distal end, a captured o-ring is held in a circumferential groove on the compressed air valve;

a catalyst valve formed on the valve stem at the distal end of the valve stem;

a dual valve housing, the dual valve housing having a catalyst input port in fluid communication with a catalyst valve seat, a compressed air input port in fluid communication with a compressed air valve seat, a mixing area in fluid communication with the catalyst valve seat and the compressed air valve seat, and an output port in fluid connection with the mixing area; and

a spring, the spring urging the valve stem towards a closed position in which the compressed air valve and captured o-ring closes against the compressed air valve seat and in which the catalyst valve closes against the catalyst valve seat, thereby blocking flow of a catalyst from the catalyst input port into the mixing chamber and blocking flow of compressed air from the compressed air input port into the mixing chamber.

2 . The dual input valve of claim 1 , whereas force applied to the first end of the valve stem compresses the spring, thereby urging the valve stem away from the closed position such that the compressed air valve and captured o-ring separates from the compressed air valve seat and the catalyst valve separates from the catalyst valve seat, thereby allowing flow of a catalyst from the catalyst input port into the mixing chamber and compressed air from the compressed air input port into the mixing chamber.

3 . The dual input valve of claim 2 , whereas a mixture of the catalyst and the compressed air exit the mixing chamber through the output port.

4 . The dual input valve of claim 1 , further comprising an o-ring within the catalyst valve seat, the o-ring contacting the catalyst valve when the dual input valve is in the closed position, thereby improving sealing between the catalyst valve and the catalyst valve seat.

5 . The dual input valve of claim 1 , further comprising a seal at an end of the compressed air input port, the seal formed around the valve stem, substantially blocking compressed air from escaping from the dual input valve while allowing actuation of the dual input valve.

6 . A method of spraying comprising:

providing the dual input valve of claim 1 ;

providing a mono input valve comprising:

a mono valve stem having an first end and a distal end,

a mono valve housing, the mono valve housing having a resin input port in fluid communication with a resin valve seat, and a resin output port in fluid connection with the resin valve seat;

a ball in communication with the resin valve seat and the mono valve stem;

a mono valve spring, the mono valve spring urging the ball towards a mono valve closed position in which the ball closes against the resin valve seat, thereby blocking flow of a resin from the resin input port to the resin output port;

providing the catalyst under pressure into the catalyst input port, providing the compressed air into the compressed air input port, and the resin under pressure into the resin input port;

actuating a trigger, the trigger operatively coupled to both the valve stem of the dual input valve and the mono valve stem;

responsive to the actuating, the mono input valve moving to a mono valve open position and the dual input valve moving to the open position, thereby initiating flow of the resin from the resin input port to the resin output port, the catalyst from the catalyst input port and compressed air from the compressed air input port through the mixing chamber and out the output port; and

emitting the catalyst, the resin, and the compressed air out of a nozzle for application on a target area.

7 . The method of claim 8 , further comprising the steps of:

releasing the trigger;

responsive to the releasing, the mono input valve moving to a mono valve closed position and the dual input valve moving to the closed position, thereby abating flow of the resin from the resin input port to the resin output port, the catalyst from the catalyst input port and compressed air from the compressed air input port through the mixing chamber and out the output port.

8 . The method of claim 6 , further comprising the step of mixing the catalyst and the compressed air in the mixing chamber.

9 . The method of claim 8 , further comprising the step of the catalyst mixed with the compressed air exiting the mixing chamber through the output port.

10 . A dual input valve comprising:

means for actuating;

a compressed air valve formed on the means for actuating, a captured o-ring is held in a circumferential groove on the compressed air valve;

a catalyst valve formed on the means for actuating;

means for housing, the means for housing having a catalyst input port in fluid communication with a catalyst valve seat, a compressed air input port in fluid communication with a compressed air valve seat, a mixing area in fluid communication with the catalyst valve seat and the compressed air valve seat, and an output port in fluid connection with the mixing area; and

means for urging the means for actuating towards a closed position in which the compressed air valve and captured o-ring closes against the compressed air valve seat and in which the catalyst valve closes against the catalyst valve seat, thereby blocking flow of a catalyst from the catalyst input port into the mixing chamber and blocking flow of compressed air from the compressed air input port into the mixing chamber.

11 . The dual input valve of claim 10 , whereas force applied to the means for actuating compresses the means for urging, thereby urging the valve stem away from the closed position such that the compressed air valve and captured o-ring separates from the compressed air valve seat and the catalyst valve separates from the catalyst valve seat, thereby allowing flow of a catalyst from the catalyst input port into the mixing chamber and compressed air from the compressed air input port into the mixing chamber.

12 . The dual input valve of claim 11 , whereas a mixture of the catalyst and the compressed air exit the mixing chamber through the output port.

13 . The dual input valve of claim 10 , further comprising an o-ring within the catalyst valve seat, the o-ring contacting the catalyst valve when the dual input valve is in the closed position, thereby improving sealing between the catalyst valve and the catalyst valve seat.

14 . The dual input valve of claim 10 , further comprising a seal at an end of the compressed air input port, the seal formed around the valve stem, substantially blocking compressed air from escaping from the dual input valve while allowing actuation of the dual input valve.
