The present invention relates to a body valve assembly for a shock absorber. According to the present invention, the body valve assembly for a shock absorber comprises: a valve body provided with one or more compression passages installed in a lower part of an inner container of the shock absorber, forming a receiving space with an open bottom face, and flowing a working fluid from the inner container to a reservoir chamber between the inner container and an outer container during a compression stroke of the shock absorber and one or more expansion passages flowing the working fluid from the reservoir chamber to the inner container during an expansion stroke of the shock absorber; a body retainer in which a compression communication passage built in the receiving space, disposed in a lower part of the valve body, and penetrating up and down to be connected with the compression passage and an expansion communication groove connected with an outlet side of the expansion passages on a top face are alternatingly disposed; and a disk module which is disposed stepwise on the bottom face of the body retainer while being in contact with the body retainer and is capable of finely controlling damping force in low speed and extremely low speed regions, dependent on a flow of the working fluid in accordance with the compression stroke and the expansion stroke. According to the present invention, riding comfort is improved by increasing a tuning degree of freedom by performing independent control of an extremely low speed section during the compression stroke and controlling preload. |
