The present invention provides a piston valve assembly of a shock absorber, comprising: a piston valve combined with and inserted by a piston rod in a central part, and repeating a pattern alternately arranging a compressive and a tensile flow path to radially arrange the compressive and the tensile flow path with respect to the piston rod; and an interlocking prevention unit mounted on an upper and a lower surface of the piston rod, blocking an outlet of the compressive flow path outlet formed on an upper surface of the piston valve and an outlet of the tensile flow path formed on a lower surface of the piston valve, and restricting that an operation fluid is supplied through the outlet of the tensile flow path in a compressive stroke and is supplied through the outlet of the compressive flow path in a tensile stroke. A tensile side is prevented from interlocking in the compressive stroke and a compressive side is prevented from interlocking in the tensile stroke, so independent tuning of the compressive and the tensile stroke can be realized. |
