Abstract

An airgun has a high pressure reservoir for providing a pressurized motive gas to a breech to fire a projectile. A regulator is intermediate the high pressure reservoir and a downstream firing pressure reservoir for providing a consistent regulated pressure of the motive gas in the firing pressure reservoir. The airgun includes a bypass line for selectively connecting the high pressure reservoir to the firing pressure reservoir, independently of the regulator. Thus, an operator can select a firing of the airgun with either a regulated gas pressure in the firing reservoir or the pressure of the high pressure reservoir.

First claim

The invention claimed is:

1. An airgun comprising:
(a) a first regulator selected to receive a high pressure gas from an upstream high pressure reservoir and pass a first regulated pressure gas to a downstream firing pressure reservoir;
(b) a bypass line fluidly connecting the high pressure reservoir and the firing pressure reservoir; and
(c) a second regulator in the bypass line, the second regulator selected to receive a high pressure gas from the upstream high pressure reservoir and pass a second regulated pressure gas to the downstream firing pressure reservoir.

2. The airgun of claim 1 , wherein the first regulator is a single stage regulator.

3. The airgun of claim 1 , wherein the second regulated pressure gas is a greater pressure than the first regulated pressure gas.

4. The airgun of claim 1 , wherein a pressure of the second regulated pressure gas is different than a pressure of the first regulated pressure gas.

5. The airgun of claim 1 , further comprising a bypass valve selectively permitting flow of high pressure gas from the upstream high pressure reservoir to the bypass line.

6. The airgun of claim 1 , further comprising a bypass selector configured to selectively fluidly connect the high pressure reservoir to one of the first regulator and the bypass line.

7. The airgun of claim 1 , further comprising a breech downstream of the firing pressure reservoir.

8. The airgun of claim 1 , wherein a volume of the firing pressure reservoir is sized to provide only a single firing of the airgun from flow passed through the bypass line.

9. The airgun of claim 1 , wherein a volume of the firing pressure reservoir is sized to provide less than three firings of the airgun from flow passed through the bypass line.

10. The airgun of claim 1 , further comprising an adapter operably retaining the first regulator.

11. The airgun of claim 10 , wherein a portion of the bypass line is formed in the adapter.
