Abstract
A control valve for an injector includes a spool valve assembly having a spool moveable between an open position and a closed position. The spool has a first hydraulic surface and a second hydraulic surface. A first chamber is in fluid communication with the first hydraulic surface of the spool and a second chamber is in fluid communication with the second hydraulic surface of the spool. An actuator is in fluid communication with the second hydraulic surface of the spool. The actuator, in an open position, provides a fluid path to ambient such that a hydraulic force acting on the first hydraulic surface of the spool becomes greater than a hydraulic force acting on second hydraulic surface of the spool. A flow path is in fluid communication with the second hydraulic surface to decrease a force acting on the second hydraulic surface of the spool during spool operation.
