A sprayer for spraying a fluid can include a sprayer body, a fluid reservoir, a trigger assembly, a flow adjustment mechanism and a flow rate indicator. The sprayer body can include a nozzle assembly that defines a fluid outlet and includes a needle arranged within a fluid conduit. The needle can be movable between a closed position and a fully opened position. The fluid reservoir can be coupled to the sprayer body and be in communication with the fluid outlet and fluid conduit. The trigger assembly can be coupled to the nozzle assembly and be configured to move the needle as the trigger assembly is depressed. The flow adjustment mechanism can be configured to adjust a flow rate of the sprayer by limiting movement of the trigger assembly and the needle. The flow rate indicator can provide an indication of the flow rate.

1. A sprayer for spraying a fluid comprising: a sprayer body including a handle portion and a nozzle portion, the nozzle portion including a nozzle assembly that defines a fluid outlet, the nozzle assembly including a fluid conduit and a needle arranged within the fluid conduit, the needle being movable to a plurality of positions between a closed position and a fully opened position, the needle closing the fluid outlet in the closed position and fully opening the fluid outlet in the fully opened position;a fluid reservoir coupled to the sprayer body and in communication with the fluid outlet and fluid conduit;a trigger assembly having a movable portion with a trigger, the movable portion being movably coupled to the sprayer body, wherein movement of the movable portion relative to the sprayer body is configured to move the needle;a flow adjustment mechanism coupled to the trigger assembly and configured to adjust a maximum flow rate of the sprayer by limiting movement of the movable portion of the trigger assembly to thereby limit movement of the needle toward the fully opened position; anda trigger plunger contacting a member of the movable portion of the trigger assembly, the trigger plunger being movable with the member of the movable portion relative to the sprayer body, the trigger plunger including a flow rate indicator that is movable relative to the sprayer body to provide an indication of an actual flow rate of the sprayer. 2. The sprayer of claim 1, wherein the member of the movable portion of the trigger assembly is the trigger. 3. The sprayer of claim 1, wherein the flow adjustment mechanism comprises a rotatable knob that acts as a mechanical stop for the movable portion of the trigger assembly, wherein rotation of the rotatable knob adjusts a maximum amount that the trigger can be moved to thereby limit the maximum flow rate. 4. The sprayer of claim 3, wherein contact between the rotatable knob and the handle portion limits movement of movable portion of the trigger assembly in a manner that moves the needle toward the fully open position. 5. The sprayer of claim 4, wherein the handle portion defines first and second apertures, the trigger plunger being movably received in the first aperture and the flow rate indicator being visible from an exterior surface of the sprayer body through the second aperture. 6. The sprayer of claim 5, wherein a position of the flow rate indicator within the second aperture when the rotatable knob is in contact with the handle portion corresponds to the maximum flow rate. 7. The sprayer of claim 1, wherein the trigger plunger is coupled to a power switch such that the power switch is turned ON when the trigger is moved toward the handle portion. 8. A sprayer for spraying a fluid comprising: a sprayer body including a handle portion and a nozzle portion, the nozzle portion including a nozzle assembly that defines a fluid outlet, the nozzle assembly including a fluid conduit and a needle arranged within the fluid conduit and extending in an axial direction, the needle being movable to a plurality of positions between a closed position and a fully opened position, the needle closing the fluid outlet in the closed position and fully opening the fluid outlet in the fully opened position;a fluid reservoir coupled to the sprayer body and in communication with the fluid outlet and fluid conduit;a trigger assembly coupled to the nozzle assembly, the trigger assembly having a trigger that is configured to coordinate movement of the needle;a flow adjustment mechanism coupled to the trigger assembly and configured to adjust a maximum flow rate setting of the sprayer by limiting movement of the trigger and the needle, the flow adjustment mechanism comprising a collar and a coupler, the collar being rotatably mounted on but axially fixed to the sprayer body, the coupler being threaded to the collar and non-rotatably coupled to the sprayer body such that rotation of the collar causes corresponding axial movement of the coupler; anda flow rate indicator coupled to the coupler for axial movement therewith, the flow rate indicator providing an indication of the maximum flow rate setting. 9. The sprayer of claim 8, wherein the coupler includes a first leg and a second leg, the first leg limiting movement of the trigger and the needle by acting as a mechanical stop for contacting a portion of the trigger assembly, and the flow rate indicator is fixed to the second leg. 10. The sprayer of claim 9, wherein the sprayer body includes an aperture, and wherein the flow rate indicator is movably disposed in the aperture, and wherein a position of the flow rate indicator within the aperture corresponds to an actual flow rate of the sprayer. 11. The sprayer of claim 10, wherein the collar includes a ridge that is arranged within a groove defined by the handle portion to inhibit movement of the collar in the axial direction. 12. The sprayer of claim 11, wherein the coupler is slidingly coupled to the nozzle portion. 13. The sprayer of claim 8, wherein the needle is biased to be in the closed position when the trigger assembly is not depressed. 14. A sprayer for spraying a fluid comprising: a sprayer body including a handle portion and a nozzle portion, the sprayer body having an exterior surface and defining a flow indicator aperture that extends through the exterior surface, the nozzle portion including a nozzle assembly that defines a fluid outlet, the nozzle assembly including a fluid conduit and a needle arranged within the fluid conduit, the needle being movable to a plurality of positions between a closed position and a fully opened position, the needle closing the fluid outlet in the closed position and fully opening the fluid outlet in the fully opened position;a fluid reservoir coupled to the sprayer body and in communication with the fluid outlet and fluid conduit;a trigger assembly coupled to the nozzle assembly, the trigger assembly comprising a trigger that is configured to move the needle as the trigger is depressed;a flow adjustment mechanism configured to limit movement of the needle in a needle opening direction; anda flow rate indicator arranged in the sprayer body and visible to a user of the sprayer through the flow indicator aperture such that a position of the flow rate indicator within the flow rate aperture corresponds to a flow rate of the sprayer. 15. The sprayer of claim 14, wherein the needle is biased to be in the closed position when the trigger is not depressed. 16. The sprayer of claim 14, further comprising a trigger plunger and a power switch for turning ON the sprayer, wherein the flow rate indicator is coupled to the trigger plunger and the trigger plunger is configured to turn the power switch ON when the trigger is depressed. 17. The sprayer of claim 16, wherein the flow adjustment mechanism comprises a rotatable knob that acts as a mechanical stop for the trigger assembly, wherein rotation of the rotatable knob adjusts the flow rate. 18. The sprayer of claim 14, wherein the flow adjustment mechanism includes a coupler coupled to a rotatable collar such that rotation of the collar moves the coupler in an axial direction, the flow rate indicator being coupled to the coupler. 19. The sprayer of claim 18, wherein the coupler includes a first leg and a second leg, the first leg limiting movement of the trigger assembly and the needle by acting as a mechanical stop for the trigger assembly and the second leg including the flow rate indicator.
