Document Type and Number:
Japanese Patent JP6351443
Kind Code:
B2
Abstract:
An elastic seal member fixedly attached to a back surface side of a disk valve is fitted in a recessed portion of a pilot body, by which a pilot chamber is formed. A valve opening of the disk valve is controlled by an inner pressure in the pilot chamber. The elastic seal member includes a thick proximal portion and a thin lip portion. A seal portion protruding on an outer circumferential portion of the lip portion is in sliding contact with an inner circumferential portion of an outer cylindrical portion of the pilot body. Deflection of the thin lip portion can reduce sliding resistance while ensuring a sealing performance of the seal portion.
