PISTON VALVE ASSEMBLY OF A SHOCK ABSORBER, CAPABLE OF EASILY CONTROLLING A DAMPING FORCE ALTHOUGH A FLOW OF AN OPERATION FLUID IS INCREASED

摘要

PURPOSE: A piston valve assembly of a shock absorber is provided to offer a proper damping force property by considering for a driving condition because the tunability of the damping force is improved.;CONSTITUTION: A piston valve assembly of a shock absorber comprises a piston valve body(131), a multi-plate disc(138), a sliding valve(155), a disc plate(156), and a valve washer(157). The multi-plate disk comprises a disc-S(138a) installed in the lower part of the piston valve body and a plate disc(138b). The sliding valve forms a inclined plane to secure a first opening gap when a multi-plate disk is transformed. The sliding valve is installed in the lower part of the multi-plate disc. The disc spring is installed to pressurize the sliding valve toward the multi-plate disc in the lower part of the sliding valve. The valve washer supports the disc spring in the lower part. The pressure of the operating fluid is more increased after securing the first opening gap. The sliding valve is moving in a straight-line while the disc spring is pressurized by the operating fluid, so that a second opening gap is secured.;COPYRIGHT KIPO 2012
