Abstract:
A high-pressure low-volume spray system includes a hose disposed between a compressor and a spray gun. The hose acts as an accumulator when the spray gun is deactivated. A check valve is disposed in a fitting connecting the hose to the compressor. The check valve includes a spring that applies a nonlinear force to a downstream end of a valve member, such that the valve member tips open in response to the pressure differential, providing a variable flowpath opening through the check valve.

Claim (Index 1):
A high-volume low-pressure (HVLP) spray system for spraying a fluid, the spray system comprising:\n an air control unit configured to generate a flow of pressurized air; a spray gun configured to spray the fluid with the flow of pressurized air; a hose extending from the air control unit and configured to provide the flow of pressurized air from the air control unit to the spray gun; and a check valve including:\n a seat; \n a valve member movable between a closed position in which the valve member is engaged with a seat and a modulated position in which the valve member is tipped partially off of the seat while a portion of the valve member is still engaged with the seat; and \n a spring that pushes the valve member into the closed position, the spring configured to be overcome by the flow of the pressurized air such that the flow of the pressurized air moves the valve member to the modulated position.
