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 15):
A check valve comprising:\n a valve member movable between a closed position, a modulated position, and an open position; and a spring that provides a nonlinear force on a downstream face of the valve member to maintain the valve member in the closed position; wherein the valve member is configured to tilt to the modulated position prior to sliding to the open position when actuating from the closed position to the open position, and wherein a portion of an upstream face of the valve member maintains engagement with a seat when the valve member is in the modulated position and another portion of the upstream face is disengaged from the seat when in the modulated position.
