Patent ID: 8752371

Claim:
An independent metering valve (IMV) assembly comprising: a metering stem including an inlet, a hydro-mechanical control valve in communication with a fluid source and the metering stem inlet, the control valve including a biasing member that biases the control valve towards an open position thereby establishing communication between the fluid source and the metering stem inlet, the control valve also including a spool with a closed end and an open end, a load signal line fluidly communicating between an outlet of the control valve positioned upstream of the metering stem inlet and the closed end of the spool, a signal line fluidly communicating between the metering stem inlet and the open end of the spool, and an orifice disposed between the load signal line and the metering stem inlet; wherein pressure in the load signal line moves the control valve towards a closed position thereby overcoming bias of the biasing member and pressure in the signal line to reduce fluid flow to the metering stem inlet during a high pressure condition.
