The invention provides a damper mechanism and a shock absorber. The damper mechanism comprises a first sleeve, a second sleeve, an upper recovery circulation valve plate, a recovery circulation gland and a limiting extension part, the first sleeve comprises a first valve seat part and a first cylindrical part connected with the first valve seat part, and the first valve seat part comprises at least one circulation channel; the second sleeve is connected with the first cylindrical part; the upper recovery circulation valve plate is located on the side, close to the second sleeve, of the first valve seat part and is configured to cover at least part of the circulation channel; the recovery circulation gland is located on the side, close to the second sleeve, of the upper recovery circulation valve block and makes contact with the second sleeve. The limiting extension part is in contact with the outer side wall of the upper recovery circulation valve plate so as to limit the movement of the upper recovery circulation valve plate in the radial direction of the upper recovery circulation valve plate; and the limiting extension part is an extension part from the second sleeve to the first valve seat part or from the recovery circulation gland to the first valve seat part. According to the damper mechanism, abrasion and noise can be reduced, the installation difficulty can be reduced, and the installation precision can be improved.

    一种阻尼器机构和减震器。该阻尼器机构包括第一套筒、第二套筒、上复原流通阀片、复原流通压盖和限位延伸部;第一套筒包括第一阀座部和与第一阀座部相连的第一筒状部,第一阀座部包括至少一个流通通道;第二套筒与第一筒状部相连;上复原流通阀片位于第一阀座部靠近第二套筒的一侧,且被配置为覆盖至少部分流通通道;复原流通压盖位于上复原流通阀片靠近第二套筒的一侧,且与第二套筒接触设置;限位延伸部与上复原流通阀片的外侧壁接触设置,以对上复原流通阀片在其径向上的运动进行限制;限位延伸部为第二套筒向第一阀座部或者复原流通压盖向第一阀座部的延伸部。该阻尼器机构可降低磨损和噪音,并可降低安装难度,并提升安装精度。
