According to one embodiment of the invention, a system for mixing particles in fluid is provided. The system includes a container defining a chamber. The chamber has a narrowing region and is operable to be pressurized. The system also includes an agitator that has one or more flexible edges positioned in contact with the surface of the narrowing region. The agitator is operable to sweep the surface of narrowing region using the one or more flexible edges to agitate the particles. The system also includes an opening that is positioned at the narrowing region.

The invention is a system for mixing first and second components of a coating to be applied to a surface in a precise ratio. The system includes a mixer within which the first and second components are combined to form a mixture. A first supply transmits the first component at a first flow rate to the mixer, the first supply producing a first flow rate signal representative of the first flow rate. A second supply which transmits the second component at a second flow rate to the mixer, the second supply producing a second flow rate signal representative of the second flow rate. First and second flow control valves are connected between the first and second supplies, respectively, and the mixer for controlling the first and second flow rates from the first and supplies in accordance with a timed duty cycle. A controller controls the operation of the first and second control valves in response to received first and second flow rate signals, such that the first and second flow control valves are never opened simultaneously.

In accordance with the present invention, there is provided a high volume, low pressure paint spray gun connectable to a paint source, an atomization air source and a shaping air source. The paint spray gun is provided with a spray gun body which is in fluid communication with the paint source, the atomization air source for atomizing paint and the shaping air source for shaping paint spray patterns. The spray gun is further provided with a nozzle which defines a paint atomizing zone for discharging atomized paint and a paint spray pattern shaping zone shaping atomized paint spray patterns. The spray gun is further provided with a paint hose, atomization air hose, and shaping air hose each having an inlet end which is connected to the spray gun body and a discharge end which is connected to the nozzle. The spray gun is further provided with a bendable, shape-retaining paint conduit having an inlet port which is connectable to the spray gun body and an outlet port which is connectable to the nozzle. The hoses extend through and are contained within the paint conduit.

In accordance with the present invention, there is provided a balanced high volume, low pressure paint spray gun. The spray gun is provided with a spray gun body connectable to a paint source and an air source. The spray gun is provided with a head insert engaged with the spray gun body. The head insert has a paint atomization chamber formed therein, a paint passage formed therethrough extending into the paint atomization chamber for receiving paint from the paint source, an atomization air passage and a shaping air passage for receiving air flow from the air source therethrough, and a balancing air passage formed therein extending into the paint atomization chamber. The spray gun further has a shaping air chamber defined by the spray gun body. The shaping air chamber is disposed in fluid communication with the air source for receiving air flow therein, disposed in fluid communication with the shaping air passage for shaping spray patterns of atomized paint, and disposed in fluid communication with the balancing air passage. The paint atomization chamber defines a paint atomization zone, a paint spray pattern shaping zone, and an air pressure zone.
