摘要： PISTON ROD HAVING CAP RECESS [00124] A piston rod for pumping paint includes an elongated cylindrical stem and a piston rod cap connected to the cylindrical stem. The cylindrical stem is formed from metal and has an outer diameter that is uniform along most or all of a length of the cylindrical stem. The piston rod cap is cylindrical and formed from metal. The piston rod cap includes an annular top portion that has an outer diameter that is larger than the outer diameter of the cylindrical stem, an annular bottom portion that has an outer diameter that is larger than the outer diameter of the cylindrical stem, and an exterior recess located between the annular top and bottom portions. The recess has an outer diameter that is smaller than the outer diameters of the annular top and bottom portions. 24.\ 20-5V Fig. 1

摘要： SPRAY GUN FOR SPRAYING PAINTS AND OTHER COATINGS A spray gun includes a gun body and a handle removably connected to the gun body. A filter is disposed in the handle for filtering particulate from the spray fluid. A trigger guard is connected to the handle and gun body and includes a contour on a lower portion of the trigger guard for receiving one or more fingers of the user that are not interfacing with and contacting the trigger. The trigger guard can be disconnected from the gun body and rotated relative to the handle. The trigger guard can contact a portion of the handle and exert torque on the handle to connect the handle to and disconnect the handle from the gun body. The portion of the handle at least partially covers a fitting connecting to the handle to provide spray fluid to the spray gun.

The packing retainer includes one or more leakage ports forming passageways between an inner surface and an outer surface of the packing retainer. The one or more packing rings surround the piston rod, are adjacent the inner surface of the packing retainer, and are positioned between the one or more leakage ports and a bottom end of the packing retainer. The one or more leakage ports are positioned so that fluid that leaks past the one or more packing rings will flow through the one or more leakage ports. 20 22-- Fig. 1
