PISTON VALVE ASSEMBLY AND CONTINUOUS DAMPING CONTROL DAMPER COMPRISING THE SAME

摘要

PURPOSE: A piston valve assembly and continuous damping control damper having the same are provided to precisely control the damping force of a vehicle by forming a slot according to the outer circumference of a flux ring of a piston valve assembly. CONSTITUTION: A piston valve assembly(100) is composed of a core assembly(110), an upper plate(120), a lower plate(130), and a flux ring(140). The core assembly comprises a solenoid coil. The upper plate is positioned on the top of the core assembly and has a first fluid passage hole connected to a first section. The lower plate is positioned in the lower part of the core assembly and has a second fluid passage hole connected to a second section. The flux ring surrounds the side of the core assembly. A first flow path connecting the first and second sections is formed between the flux ring and the core assembly. A second flow path connecting the first and second sections is formed on the outer side of the flux ring.
