Abstract: A handheld fluid sprayer is configured to draw spray fluid from a reservoir mounted on the fluid sprayer and eject the spray fluid through a nozzle. The reservoir is removably mounted to the fluid sprayer. A filling apparatus can connect to the reservoir at the same interfaced that the reservoir connects to the fluid sprayer. The filling apparatus can be used to refill the reservoir. A priming pathway extends through the fluid sprayer and routes air out of the reservoir to prime the pump. The priming pathway extends from the reservoir and to a side of the pump opposite the reservoir. The nozzle includes a spray tip having a tip piece seated within a pre-orifice piece.

Abstract: Various embodiments concern a handheld paint sprayer for spraying a paint. The sprayer can comprise a shell body comprising a door that, when opened, exposes an opening into an interior of the shell body, the door configured to close over the opening. The sprayer can further comprise a trigger connected to a handle, a motor in the interior, and a paint reservoir connected to the shell body. The sprayer can further comprise a nozzle in fluid communication with the reservoir and a pump located in the interior of the shell body. The pump is operated by the motor, the pump configured to pump the paint from the reservoir out of the nozzle as a spray. The pump is removable from the interior of the shell body through the opening when the door is opened but is not removable through the opening when the door is closed.

Abstract: A fluid sprayer includes a spray gun that is configured to output a spray of fluid for application on a substrate. A trigger of the spray gun is operatively connected to a controller to control actuation of a pump that drives the spray fluid to the spray gun. A solenoid is connected to a spray valve of the spray gun to actuate the spray valve open to cause spraying by the fluid sprayer.

Abstract: A power tool attachment is configured to connect to a power tool at a static interface and a dynamic interface. The static interface statically fixes the power tool and power tool attachment together. The dynamic interface provides rotational motion generated by the power tool to the power tool attachment. The rotational motion is provided to a drive of the power tool attachment that converts the rotational motion to a linear reciprocating output.

Abstract: A tube dampener (12) for a fluid sprayer (10) is disposed downstream of the pump (18) to receive spray fluid output by the pump. The tube dampener includes a rigid body (24) and a flexible tube (26) disposed within the rigid body. The flexible tube is resilient to smooth pressure fluctuations in the spray fluid output by the pump, providing consistent pressure at a spray nozzle (28) downstream of the tube dampener (12).

Abstract: A spray gun adapter establishes fluid communication between a fluid pump of a handheld airless spray gun and an applicator accessory. The adapter comprises an adapter body, a head attached to the adapter body, and a protrusion. The adapter body comprises an upper portion, a lower portion, a radial inlet located in a sidewall of the adapter body between the upper and lower portions, and an adapter bore having a first diameter in fluid communication with the radial inlet. The head comprises a cavity in fluid communication with the adapter bore and having a second diameter larger than the first diameter, an adapter outlet located in the upper portion of the adapter body and in fluid communication with the cavity, and a handle extending radially from the head. The protrusion extends radially from the adapter body between the upper and lower portions of the adapter body.

Abstract: A spray tip includes a cylindrical body having a through hole oriented along a fluid flow axis, and a spray outlet piece and upstream chamber piece located in the through hole. The spray outlet piece includes an outlet aperture configured to atomize a spray fluid. The upstream chamber piece includes an internal aperture wall with an upstream surface and a downstream surface, and an aperture through the wall. The aperture includes an inlet orifice and an outlet orifice. The spray tip further includes a turbulation chamber defined by the spray outlet piece and the upstream chamber piece.

Abstract: Various embodiments concern a sprayer having a blower that outputs a HVLP flow of air into a hose, the hose connecting with a spray gun. A pressure sensor measures pressure of the HVLP air within the hose via a tube that branches from a fitting to which the hose connects. If the sensor indicates that the pressure level has increased above a threshold amount, indicating that the trigger of the spray gun is not being actuated, then power output to the blower is reduced (e.g., stopped). HVLP air is trapped within the hose by two valves when the trigger is not actuated. When the sensor indicates that the pressure level has decreased, corresponding to release of the trapped HVLP air into the gun for spraying by actuation of the trigger, power to the blower is increased (e.g., resumed).

Abstract: A fluid sprayer includes a pump and an electrostatic module configured to provide an electrostatic charge to spray fluid. The electrostatic module is electrically connected to a conductive component of the fluid sprayer, such as a fluid displacement member, fitting, cylinder, or spray tip, to charge the spray fluid via the conductive component. The fluid is electrostatically charged prior to exiting the fluid sprayer.
