A solenoid valve is installed between a high-pressure side leading to a compressor of a fuel-injection pump and a low-pressure side to adjust the fluidic connection therebetween. This valve comprises a valve body, an armature, a solenoid which moves the armature, and a return spring. In the solenoid valve, a passage connecting an armature chamber and a balance chamber is formed around the edge of the opposite side of the armature, a rising-pressure preventing passage is provided to prevent an increase in pressure in the armature chamber, and compensation mechanism is provided in the junction area between the different members which accommodate the valve body, to thereby absorb a gap or misalignment between the sliding holes of the different members.
