るデイーゼルエンジンの燃料噴射時期調整装置。[Claims for Utility Model Registration] It has a cylinder whose both ends are closed, and a piston that is slidably inserted into the cylinder, and the interior of the cylinder is opened by the piston. It is divided into a pressure chamber and a second pressure chamber, and a compression coil spring is arranged in the first pressure chamber to press the piston in a direction to increase the volume of the first pressure chamber, The suction side fuel pressure of the feed pump is introduced into the first pressure chamber, and the discharge side fuel pressure of the feed pump is introduced into the second pressure chamber, so that the suction side fuel pressure of the feed pump and the feed pump A fuel injection timing adjustment device that changes the fuel injection timing by using movement of the piston caused by a pressure difference between the first pressure chamber and the second pressure chamber. The pressure chamber is communicated with the pressure chamber by a communication passage, and a valve device is provided in the middle of the communication passage to vary the effective flow cross-sectional area of the communication passage. A fuel injection timing adjustment device for a diesel engine, characterized in that a filter is disposed between an opening in the second pressure chamber and the valve device.
