摘要：
Apparatuses, tools, assemblies, and methods are disclosed for reducing vibration. A shock absorption apparatus may include a stator and a rotor inside the stator. A first piston section may be included and define a first piston chamber having a first piston therein. The first piston chamber may be fluidly coupled to a first end portion of an annulus defined in a region between the stator and the rotor. A second piston section may also be defined and may include a second piston chamber with a second piston therein. The second piston chamber may be fluidly coupled to a second end portion of the annulus.
