Abstract

PURPOSE:To improve quick response of a slider in an oil hydraulc timer for controlling fuel injection timing, by providing a pressure regulating device to the return side of an advance angle chamber provided to one side of the slider and performing a pressure rise in the advance angle chamber in a short time at idling operation. CONSTITUTION:An oil hydraulic timer 10 is constituted such that its input and output shafts are spline coupled in a casing (not shown) through a slider 13, and advance and delay angle chambers 11 and 12 are provided to both sides of the slider 13. Then the slider 13 selectively feeds pressure oil from an oil pump 15 to each chamber 11, 12 by a spool solenoid valve 14 to control fuel injection timing. In this case, a spool land at a side of the advance angle chamber 11 in the solenoid valve 14 is formed with a notch (not shown) as a communication passage to always feed the pressure oil of the pump 15 to the advance angle chamber 11. Further a pressure regulating device 22 is provided to the return side of the advance angle chamber 11 to limit a return amount at idling operation.
