This is American Pneumatic Tool part number 1280582947, which replaced the older number 17676 throttle valve, stocked at Crowder Supply as APT17676. This is control gear it meters air to the rock drill. A worn control gives creep, hard starting, or a tool that will not shut off cleanly.
It is called out in the parts diagram for the 109 Mini Rock Drill. The tool itself is the APT 109 Pneumatic Rock Drill. Compare it to the reference callout on the diagram to be sure it is the position you need.
Work through the rest of the assembly on the same breakdown, or start over from the parts diagram hub. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
