Spray gun system

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 ().

Handheld fluid sprayer

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.

Airless handheld sprayer repair

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.

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 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.

A spray tip includes a body portion with an aperture extending through the body portion from an aperture inlet to an aperture outlet, and a handle portion attached to the body portion. The handle portion is configured to rotate the body portion. A retainer with an upstream end and a downstream end is positioned in the aperture of the body portion. A pre-orifice piece with an upstream end and a downstream end is positioned in the aperture of the body portion. A tip piece with an upstream end and a downstream end is positioned in the aperture of the body portion. The downstream end comprises an outlet nozzle.

Airless sprayer

A fluid sprayer comprises a fluid source, a spray nozzle, a pump, and a handle with a base. The spray nozzle is disposed to accept a spray tip with an outlet aperture. The pump is disposed to pump fluid from the fluid source out the outlet aperture of the spray tip. The base has a sealable storage slot sized to contain and form an air seal with the spray tip when not in use.
