Paint sprayer

A paint sprayer comprising:

• a reservoir;
• a housing having an air supply chamber, an air passageway in fluid communication with the air passageway, a paint conduit, a reservoir coupler, a paint inlet conduit, a reservoir pressurization conduit, the reservoir being mounted to the reservoir coupler such that the paint inlet conduit couples the reservoir in fluid communication with the paint conduit and the reservoir pressurization conduit couples the reservoir in fluid communication with the air passageway, the paint inlet conduit and the reservoir pressurization conduit extending at least partly through the reservoir coupler;
• a nozzle coupled to the housing, the nozzle having a fluid outlet that is in fluid communication with the paint conduit;
• an air horn coupled to the housing and in fluid communication with the air passageway;
• a needle received in the paint conduit and being movable within the paint conduit between a first position and a second position, wherein the needle comprises a needle end that closes the fluid outlet in the nozzle when the needle is in the first position;
• a trigger assembly having a trigger and a trigger collar, the trigger being pivotally coupled to the housing, the trigger collar coupling the trigger and the needle such that pivoting of the trigger relative to the housing causes corresponding axial translation of the needle in the paint conduit;
• and
• an adjustment mechanism having a knob that is threadably mounted directly to the trigger, wherein the knob is configured to contact the housing to limit pivoting motion of the trigger relative to the housing in a direction that moves the needle toward the second position.
