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. A method of operating a pressurized gas gun, the method comprising:
setting a bypass valve in one of a first configuration and a second configuration;
supplying a higher pressure gas from a high pressure gas reservoir to a first port of the bypass valve;
directing the higher pressure gas from the first port of the bypass valve toward a firing reservoir;
exposing, in response to actuation of a trigger assembly, a projectile to the pressure of the gas in the firing reservoir to cause the projectile to pass through and out of a barrel;
wherein directing the higher pressure gas from the first port of the bypass valve toward the firing reservoir in the first configuration of the bypass valve includes directing the higher pressure gas through a regulated path to supply the firing reservoir with a lower pressure regulated gas and wherein directing the higher pressure gas from the first port of the bypass valve toward the firing reservoir in the second configuration of the bypass valve includes directing the higher pressure gas to a bypass line to supply the firing reservoir with the higher pressure gas.

2. The method of claim 1 , wherein directing the higher pressure gas to the bypass line in the second configuration of the bypass valve includes directing the higher pressure gas through the bypass line fluidly connecting the first port of the bypass valve to the firing reservoir.

3. The method of claim 1 , wherein directing the higher pressure gas through the regulated path in the first configuration of the bypass valve includes directing the higher pressure gas from the first port of the bypass valve through a first regulator to transform the higher pressure gas to the lower pressure regulated gas of a predetermined pressure level and directing the lower pressure regulated gas to the firing reservoir.

4. The method of claim 1 , wherein directing the higher pressure gas through the regulated path in the first configuration of the bypass valve includes directing the higher pressure gas from the first port of the bypass valve through a first regulator and from the first regulator to a second regulator to transform the higher pressure gas to the lower pressure regulated gas of a predetermined pressure level and directing the lower pressure regulated gas to the firing reservoir.
