Abstract:
A spray gun includes a valve cartridge configured to be axially installed and removed as a single piece. The valve cartridge includes the wear components of the spray gun. A trigger of the spray gun is configured to actuate a slider of the valve cartridge to control spraying by the spray gun. The trigger includes arms that are mounted to the spray gun by a pivot mechanism. The pivot mechanism can be disengaged from the arms to allow the trigger to slide between a spray position, where the trigger prevents forward axial movement of the valve cartridge, and a repair position, where the valve cartridge can move axially forward. The trigger also includes upper and lower portions that are movable relative to each other, such that the length of the trigger can be adjusted.

Claim (Index 1):
A valve cartridge for a paint spray gun, the valve cartridge comprising:\n a housing having:\n a first end, a second end, a housing body extending between the first end and the second end; \n a cartridge outlet extending through the first end; \n a chamber within the housing; \n at least one side port extending through the housing and in fluid communication with the chamber; and \n a first annular groove disposed about an exterior of the housing between the first end and the at least one side port, wherein a first annular seal is disposed in the first annular groove; \n a second annular groove disposed about the exterior of the housing, wherein a second annular seal is disposed in the second annular groove; \n a valve disposed within the housing and configured to control the flow of paint from the chamber through the cartridge outlet; a spring configured to bias a valve member of the valve towards a closed state; a slider disposed at least partially outside of the housing; and a stem extending along an axis between the valve member and the slider; wherein the valve member and the slider are fixed with respect to the stem such that the slider can actuate the valve member from the closed state to an open state via the stem; wherein the at least one side port is disposed axially between the first annular groove and the second annular groove; and wherein the housing, the valve, the spring, the slider, and the stem form a discrete assembly configured to control spraying of paint.
