Abstract
An air compressed gun (210) is provided having a stock (211), multiple barrels (212), a trigger (213) and a manual air pump (214). A pressure chamber (216) and release valve (217) is coupled to each barrel which is controlled by the trigger.
Claims17
A compressed air gun for firing projectiles comprising:
- pump means for compressing air;
- a plurality of projectile launch tubes each configured to hold a projectile,
- a plurality of pressure chambers, each said pressure chamber being in fluid communication with one said launch tube and with said pump means,
- a plurality of release valves, each said release valve being associated with one said launch tube and one said pressure chamber so as to control the release of pressurized air from said pressure chamber to said launch tube;
- and
- a trigger coupled to said release valves for actuation thereof.

A compressed air gun for firing projectiles comprising:
- pump means for compressing air;
- a plurality of projectile launch tubes each configured to hold a projectile,
- a pressure chamber in fluid communication with said launch tubes,
- a conduit extending between said pressure chamber and said plurality of projectile launch tubes,
- a release valve associated with each said pressure chamber which controls the release of pressurized air from said pressure chamber to said launch tubes;
- and
- a trigger coupled to said release valves for actuation thereof,
- whereby actuation of the trigger causes compressed air within said pressure chamber to be directed into all projectile launch tubes for the simultaneous launching of projectiles therefrom.

A compressed air gun for firing projectiles comprising:
- pump means for compressing air;
- a plurality of projectile launch means, each said launch means having a launch tube configured to hold a projectile, a pressure chamber in fluid communication with said launch tube and with said pump means, and a pressure actuatable release valve means for controlling the release of pressurized air from said pressure chamber into said launch tube;
- and
- trigger means for sequentially actuating each of said release valve means, said triggering means comprising a manifold in fluid communication with said pump means having a vent adjacent one end of said manifold and a series of ports each of which is in fluid communication with one of said projectile launch means valve means, and a plunger having a seal in sealing engagement with said manifold and that extends into said manifold through said one end,
- whereby with the plunger seal positioned adjacent the manifold one end pressurized air from the pump means pressurizes the manifold and the pressure actuated release valves, and an inward stroke of the plunger seal past each port causes the port to be in fluid communication with the manifold vent so as to actuate the pressure actuated release valve coupled thereto.
