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 16):
The check valve of  claim 15 , further comprising:\n a cage; and a seat disposed at an upstream end of the cage; wherein the spring is disposed in the cage; and wherein the valve member is disposed within the cage between the spring and the seat, the upstream face of the valve member facing the seat and a downstream face of the valve member facing the spring.
