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 pressurized fluid gun comprising:
- an electric power source;
- an electrically motorized air pump coupled to said electric power source;
- a fluid pressure tank in fluid communication with said motorized air pump;
- a pressure chamber in fluid communication with said fluid pressure tank, said pressure chamber having an outlet;
- a release valve in fluid communication with said outlet which controls the release of pressurized fluid from said pressure chamber through said outlet;
- and
- trigger means for actuating said release valve;
- and
- pressure sensitive actuation means in fluid communication with said pressure chamber for sensing the fluid pressure associated with said pressure chamber and energizing said motorized air pump when the sensed fluid pressure is within a range below a desired threshold fluid pressure level.
