摘要： A saddle seal assembly for a high-pressure airless spray nozzle having a spray tip includes a metal sealing sleeve, a cylindrical elastic seal, and a metal sleeve insert. The metal sealing sleeve may include a first saddle-shaped semi-cylinder surface closely matching with an outer surface of the spray tip to form an outer hard sealing structure. The cylindrical elastic seal may include a second saddle-shaped semi-cylinder surface closely matching with the outer surface of the spray tip to form an inner flexible sealing structure. The metal sleeve includes a hollow cylinder shape that matches the inner surface of the cylindrical elastic seal. A first end portion of the cylindrical elastic seal is configured to be inserted into the metal sealing sleeve, and the first saddle-shaped semi-cylinder surface and the second saddle-shaped semi-cylinder surface are configured to be spliced to form a continuous saddle-shaped semi-cylinder surface, to thereby seal a stepped inlet hole of the high-pressure airless spray nozzle. The metal sleeve insert is attached onto the inner surface of the cylindrical elastic.

摘要： A paint container for use with a reusable dispensing apparatus, and the reusable dispensing apparatus are provided to dispense paint under pressure. The paint container includes a housing defining an interior space that is devoid of an internal valve, and a combination comprising a propellant combined with paint within the interior space. A container cap is installed on the housing to enclose the propellant combined with the paint within the interior space at an elevated pressure, and defines a channel that cooperates with a portion of the housing. A compressible gasket is disposed within the channel and compressed between the container cap and the portion of the housing to form a seal that interferes with an escape of the propellant combined with the paint between the container cap and the housing. A releasable fastener engages releasably couples the reusable dispensing apparatus to the container cap.

摘要： A paint spray gun includes a gun body formed as a unitary one piece structure composed of a tubular body portion, a valve connection portion, an air passageway portion and a feed connection portion. A spray cap is disposed on the tubular body portion and has a cap opening. The tubular body portion has an air chamber that is covered by the spray cap and that communicates with said cap opening, and a feed passage connected to the chamber. The valve connection portion, the air passageway portion and the feed connection portion are formed as one piece with the tubular body portion without welded joints.

摘要： An overspray protection device has a housing which is engageable directly to a paint spray gun or to a conduit extending from the paint gun. An interior cavity of the housing provides a pathway for a stream of paint emitted by a spray nozzle to a surface being painted, which is protected from wind by a sidewall defining the shape of the housing and the interior cavity.
