The invention relates to an electromagnetic valve shock absorber. The shock absorber comprises an oil storage cylinder, a working cylinder, a piston rod, a middle cylinder, a compression valve and anelectromagnetic valve, wherein the compression valve is fixedly arranged at the lower end in the oil storage cylinder, the working cylinder is coaxially sleeved with the oil storage cylinder, the lower end of the working cylinder abuts against the compression valve, the upper end of the working cylinder is in sealed connection with the oil storage cylinder, the middle cylinder sleeves the outer side of the working cylinder in a sealing mode and located in the oil storage cylinder, the piston rod is arranged in the working cylinder in an axial sliding mode, a piston valve is arranged at the lower end of the piston rod, the upper end of the piston rod extends out of the working cylinder and the oil storage cylinder upwards, a circulation valve element is arranged at a second communication hole, an electromagnetic valve is arranged on the outer side of the oil storage cylinder, a valve rod of the electromagnetic valve corresponds to the end, close to a second flow guide cavity, of the circulation valve element. The electromagnetic valve shock absorber aims to solve or at least ease the problems that according to an existing passive shock absorber, changing cannot be conducted according to requirements after damping force adjustment is completed, and an intermediate cylinder is complex in structure and not easy to machine.
