  • Patent number: 10337625
    Abstract: A slide flow distributor to direct and modulate a gaseous fluid, in inlet and outlet. This regulation is carried out by means of a spool, which conveys compressed air in a determined charging direction and puts in communication the other chamber with the environment at the same time. This is a servo-actuator which can be used in the field of pneumatic systems of valve actuation. It has a specific pneumatic servo-actuating system using compressed air. This distributor uses a linear motor using a new pneumatic servo-actuator which generates a force in the same direction of the axial force of the motor, with the result that the spool is accelerated in a predetermined direction. The pneumatic servo-actuator is made of a profiled body, a plurality of balls and corresponding elastic means which press the plurality of balls on the side surface of the profiled body.

    Abstract: An ergonomic handle assembly can allow an operator to comfortably support weight of a fluid filled reservoir connected to a fluid applicator sprayer. Any combination of first, second and third shoulders can be formed on the handle assembly to provide increased support surface area in three dimensions with respect to a hand of an operator supporting the fluid applicator spray gun for distributing weight across both the palm and fingers through a proximal support surface of the first support shoulder, the distal support surface of the second support shoulder, and the proximal support surface of the third support shoulder. The increased support surface area can allow an operator to support and handle the fluid applicator spray gun with reduced gripping force when compared to existing fluid applicator spray guns. The reduced gripping force can reduce the likelihood of repetitive stress syndrome injuries to the hand and arm of an operator.

  • Patent number: 8844840
    Abstract: A paint sprayer is configured for use with a paint container. The sprayer includes a housing having an air inlet and a nozzle located on the housing. Movable grip members are supported on the housing. The grip members are located in a circular array with an inner diameter that is greater than the outer diameter of the paint container. A ring extends circumferentially about the circular array of grip members, and is supported on the housing for rotation relative to the housing. When the ring rotates relative to the housing, it moves the grip members to a condition in which the inner diameter of the circular array is not greater than the outer diameter of the paint container.

  • Publication number: 20140263686
    Abstract: A spray gun has a spray gun body with at least one fluid input port. A nozzle is removably affixed to the spray gun body and valves are in fluid communication between each of the at least one fluid input ports and the nozzle. A trigger is movably attached to the spray gun body and is operatively coupled to the valves such that operation of the trigger opens each of the valves and fluid flows from the at least one fluid input port through the valves to the nozzle. Included are at least two pairs of handle grips. Each of the at least two pairs of handle grips are of a different size, each size corresponding to a hand size, and one of the at least two pairs of handle grips is removable affixed to the spray gun body.

  • Patent number: 8807464
    Abstract: A nozzle assembly for a material application device includes an expansion chamber for slowing down the velocity of powder fed to the nozzle from a dense phase pump. The nozzle assembly includes a nozzle insert that forms the expansion chamber and provides air assist function. The nozzle includes an integral deflector, and further includes a passageway for a charging electrode so that the electrical path is routed away from the powder path, while permitting the electrode tip to be centered in the powder spray pattern from the nozzle. The nozzle also includes air wash for the electrode. The nozzle outlet orifice has a cross-sectional area that is equal to or greater than the inlet cross-sectional area so that a slow moving dense phase powder cloud is produced by the nozzle.
