Patent ID: 7036756

Claim:
An anti-sputter fluid flow control apparatus, comprising: a valve body; said valve body having an intake port, a central channel and an output port; a chamber disposed in said central channel; a valve seat disposed within said chamber; a biased valve head; said valve head having a cylindrical body; said valve head having a generally rounded contact surface; wherein said valve seat has a seat surface adapted to mate with said rounded contact surface of said valve head; a bore in said valve seat fluidly connecting said intake port and said seat surface; and means for increasing and decreasing the bias on said valve head; said valve head configured to allow fluid to flow between said intake port and said output port when the pressure of said fluid is sufficient to overcome the bias on said valve head; said valve head configured to engage said valve seat when the pressure of the flow of fluid drops to a level insufficient to overcome the bias on said valve head.
