Claims (1)
料噴射ポンプの駆動回転数に関係して油圧タイマのピス
トンに作用する油圧に抗してこのピストンに作用するば
ねのばね力を、特定の大気圧以下において弱くすること
を特徴とする、燃料噴射ポンプの噴射時期調整装置。In an injection timing adjustment device that has an advance hydraulic timer, the spring force of the spring that acts on the piston of the hydraulic timer against the hydraulic pressure that acts on the piston in relation to the driving rotation speed of the fuel injection pump is adjusted to a certain level. An injection timing adjustment device for a fuel injection pump, which is characterized by making the injection timing weaker below the atmospheric pressure.
