Abstract

PURPOSE:To elevate output of engine, reduce the consumption of fuel and to improve responce of control system by providing a throttle flow passage in an oil pressure transfer valve between an oil pressure actuator for control of fuel injecting pump and the source of oil pressure. CONSTITUTION:An oil pressure actuator 2 controls a fuel injection pump 3 changing a relative rotating phase angle between input axle 1a and otput axle 1b. An oil pressure transfer valve 4 is internally equipped with a throttle flow passage 4j in the flow passage from the source of oil pressure 5 to a reservoir 5b in the neutral switching position 4B. When the switching is made to a switching position 4D, oil pressure from a hydrualic pump 5 is transmitted to the pushing-aside chamber 2b in a short time. Thus if the operational oil pressure of hydraulic control system is low, the time lag of responce may be sufficiently lessened.
