Spray gun and associate parts washer and recycler

A cleaning system for cleaning paint from internal passages of a paint laden spray gun of the type having a pressure air inlet which in normal paint spraying operation receives pressurized air to create an action to draw paint through a paint inlet and thereafter force the paint out through a connecting paint outlet when a trigger mechanism of the paint gun is activated so to open communication between the paint inlet and outlet comprising:

• a work chamber;
• an unpressurized reservoir into which is received cleaning fluid, the reservoir being remote from the work chamber;
• fluid transport means for interconnecting the work chamber and the unpressurized reservoir including at least a first outlet through which pressurized cleaning fluid is forced therethrough;
• pump means, in communication with the fluid transport means, for providing the only source of pressurizing the cleaning fluid and causing same to flow from the reservoir to the first outlet;
• said first outlet including means for supporting the paint inlet of the spray gun wherein the inlet of the paint gun is loosely supported on the supporting means solely by virtue of the weight of the spray gun in a manner that the pressurized cleaning fluid flowing from the first outlet enters the paint inlet and flows through internal passages of the spray gun and then out through the paint outlet and wherein the pressure air inlet of the spray gun is exposed to atmosphere during the time that cleaning fluid is being forced into the paint inlet and wherein the trigger mechanism of the spray gun is activated prior to the activation of the pump means.
