## Abstract

A plural component spray gun system for use with a reactor having a chemical supply, a heater, a pump and a compressor, includes a trigger module with a spool valve having an air inlet and an activating outlet and an deactivating outlet; and an air body connected to the trigger module by an intermediate extending portion and having a mixing chamber to combine pressurized chemical components upon activation of a piston by pressure from the activating outlet.

## Claims

### Claim 1

A plural component spray gun system for use with a reactor having a chemical supply, a heater, a pump and a compressor, comprising:
a) a trigger module comprising a spool valve having an air inlet and an activating outlet and an deactivating outlet;
b) an air body comprising a mixing chamber to combine pressurized chemical components upon activation of a piston by pressure from the activating outlet; and
c) an elongate intermediate extending portion, wherein the trigger module and air body are connected to different ends of the intermediate extending portion such that the trigger module and air body are separate from each other.

### Claim 2 (depends on 1)

The system of claim 1 wherein the intermediate extending portion comprises a plurality of interconnecting extensions which may be adjusted in angle relative to each other and locked together at a desired angle relative to each other.

### Claim 3 (depends on 1)

The system of claim 1 wherein the air body may be adjusted in angle relative to the intermediate extending portion, and locked at a desired angle relative to the intermediate extending portion.

### Claim 4 (depends on 1)

The system of claim 1 further comprising a first line connecting the activating outlet to the air body to activate the piston, and a second line connecting the deactivating outlet to the air body to deactivate the piston.
