The invention provides a novel internal and external double-electromagnetic-valve shock absorber which comprises an oil storage cylinder, a middle cylinder, a working cylinder and a piston rod and further comprises a recovery valve assembly, a compression valve assembly, a piston assembly, a recovery electromagnetic valve and a compression electromagnetic valve. The recovery solenoid valve is connected to the lower end of the piston rod, and the recovery valve assembly is connected to the lower end of the recovery solenoid valve and divides the working cylinder into an upper cavity and a lower cavity which are communicated with the recovery solenoid valve and the recovery valve; the compression valve assembly is arranged at the bottom end of the working cylinder and enables a lower cavity of the working cylinder to be communicated with the oil storage cylinder. The compression electromagnetic valve is connected to the outer wall of the oil storage cylinder and enables the lower cavity of the working cylinder to be communicated with the oil storage cavity. According to the novel internal and external double-electromagnetic-valve shock absorber, the space of a chassis can be reduced, and damping adjustment in a large range is achieved.

    本发明提供一种新型内外置双电磁阀减振器,包括贮油缸、中间缸、工作缸和活塞杆,还包括复原阀组件、压缩阀组件、活塞组件和复原电磁阀、压缩电磁阀;复原电磁阀连接在活塞杆的下端,复原阀组件连接在复原电磁阀的下端,并将工作缸分隔为由复原电磁阀和复原阀连通的上腔和下腔;压缩阀组件设置在工作缸的底端并将工作缸的下腔与贮油缸连通,压缩电磁阀连接在贮油缸的外壁上并将工作缸的下腔与贮油腔连通。该新型内外置双电磁阀减振器,能够减小底盘空间,并实现了较大范围的阻尼可调。
