<p>An actuation valve (90) for a hydraulically-operated fuel injector (10) includes an actuator (92) having a plunger (98) and a spool valve (104) coupled to the plunger (98). The spool valve (104) includes a high pressure port (122) and is operable by the actuator (92) to selectively place the high pressure port (122) or the low pressure port (120) in fluid communication with an injection mechanism (35) of the injector (10).</p> |
