Abstract
A fluid gun (700) is disclosed having an electric pump (704) for conveying air to a pressure chamber (701) having a release valve (702) for controlling the release of fluid. The activation of the electric pump is controlled by a pressure sensitive actuation switch (713) which senses the pressure within the pressure chamber and activates the pump when the sensed pressure falls within a minimal range.
Claims6
A compressed air gun for firing projectiles comprising:
- an electric power source;
- an electrically motorized air pump coupled to said electric power source;
- a pressure chamber in fluid communication with said air pump;
- a launch tube in fluid communication with said pressure chamber;
- a release valve in fluid communication with said launch tube which controls the release of pressurized air from said pressure chamber to said launch tube;
- and
- trigger means for actuating said release valve;
- and
- pressure sensitive actuation means in fluid communication with said pressure chamber for sensing the air pressure associated with said pressure chamber and energizing said motorized air pump when the sensed air pressure is within a select pressure range.
