Cordless, self-contained, handheld spray gun

A self-contained, cordless, handheld spray gun, comprising:

• a gun shaped body having a barrel portion defined by a longitudinal first end and a longitudinal second end, said gun body having a central passage defined through said longitudinal first end to said longitudinal second end and having a first bore defined at the first longitudinal end, an inlet bore at the top of the gun body proximate the longitudinal first end:
• said gun shaped body also having a handle portion defined by a lateral first end and a lateral second end, said body having a central passage defined from the lateral first end to said lateral second end;
• the longitudinal first end and longitudinal second end being integral with, but generally orthogonal to, said lateral first end and lateral second end;
• the longitudinal first end being about 90 degrees away from said lateral first end;
• a nozzle assembly connected to said gun body at said first longitudinal end;
• at least one fluid nozzle orifice defined therethrough the nozzle assembly;
• a valve mechanism coupled to the fluid nozzle;
• said valve mechanism operable to adjust the aggregate size of the fluid orifice;
• at least one tubular member comprising air passages;
• at least one tubular member comprising fluid passages;
• a source of pressurized gas;
• an air reservoir coupled to said gun body;
• a pressure sensor coupled to the air reservoir;
• a fluid chamber;
• at least one gas nozzle orifice defined therethrough the nozzle assembly, said nozzle assembly able to regulate the gas flow and gas pressure at the gas nozzle orifice;
• the at least one tubular member comprising air passages commencing from the source of pressurized gas and terminating at the at least one gas nozzle orifice;
• a fluid container having a plurality of closed sides and an open top and a bottom;
• the bottom of the fluid container having a bore there-through and being adapted to attach securely to the top of the gun body proximate the longitudinal first end;
• the bottom of the fluid container being adapted to securely mate with the inlet bore in the top of the gun body;
• a fluid container covering, adapted to mate to the open top of the fluid container;
• the fluid container covering having a container covering bore through the top thereof;
• the at least one tubular member comprising fluid passages being coupled and in communication with the fluid container through the bottom bore of the container and the inlet bore in the top of the gun body;
• the at least one tubular member comprising fluid passages commencing from the fluid container and terminating at the fluid chamber and in communication with the fluid nozzle;
• the air passage tubular members being coupled to the container covering bore on the top of the fluid container covering;
• a trigger mechanism located proximate the handle portion of the gun body;
• and
• the trigger mechanism having a variable pull such that the at least one fluid nozzle orifice opens variably from closed to full open, depending on the force applied to the trigger mechanism.
