Abstract
Devices and methods for reducing vibrations. Methods include inserting a device for reducing vibrations within a pressure-control device, where the pressure-control device includes at least one movable element. The device for reducing vibrations includes a first body comprising a first material inserted adjacent to the at least one movable element and a second body comprising a second material, positioned radially opposite the first body. In one or more embodiments, the method also includes moving the at least one movable element of the pressure-control device and absorbing a portion of vibrations, introduced by moving the at least one movable element, using the device for reducing vibrations.
Claims8
A first device for reducing vibrations, comprising:
- a first body having a first outward-facing outer wall surface and a first inward-facing inner wall surface, wherein a portion of the first outward-facing outer wall surface is removed to form a first cutout portion;
- and
- a second body having a second outward-facing outer wall surface and a second inward-facing inner wall surface, the second body comprising:
- a second body first nub extending from the second body proximate a second body upper side and a second body second nub extending from the second body proximate a second body lower side;
- a first body first step abuts a second body first nub lower side;
- and
- a first body second step abuts a second body second nub upper side,
- wherein the second body is radially stacked around the first outward-facing outer wall surface within the first cutout portion of the first body, and
- wherein the first device is configured to absorb mechanical vibrations within a pressure-control device.
