| Abstract: |
The invention is an attachment for airguns and/or similar devices powered by compressed gas. The unit is multi functional in that it facilitates rapid refilling of a connected gas supply vessel from a bulk supply source, without the necessity of removing the supply vessel from the airgun. The adaptor also provides the basic benefits of a simple expansion chamber, effectively providing compensation for periodic introduction of any liquid gas propellant from the gas supply vessel caused by handling or orientation of the airgun and/or aerosol supercharging.

What is claimed is:
1. A multi function adaptor for use with a gas operated airgun facilitating use of a compressed gas propellant and the refilling of a gas supply vessel connected to said airgun from an external bulk gas supply source, said adaptor comprising:
- a strut comprising a hollow cylinder including external and internal walls;
- a threaded section at one end of said strut adapted to be connected to said airgun;
- a first sleeve comprising a hollow cylinder positioned over an upper section of said strut;
- a first sump;
- said first sleeve including a first orifice connected to said first sump, said orifice adapted to be connected to said gas supply vessel;
- a second sump;
- a second orifice connecting said first sump to said second sump;
- a reverse check valve internal to said strut;
- a third sump;
- a third orifice connecting said third sump to said strut external walls;
- a second sleeve positioned over the lower portion of said strut, sealing said third orifice facilitating the flow of gas from said gas supply vessel through said adaptor to said airgun;
- and as a replacement for said second sleeve, a third sleeve, positioned over the lower portion of said strut;
- said third sleeve including an orifice in connection with said strut third orifice extending to said third sump;
- facilitating the flow of gas from an external bulk supply source through said adaptor to said gas supply vessel.
