<p>A damper for a lever mechanism wherein a lever beam is mounted for pivotal movement about a pivot axis. The damper includes a rigid enclosure formed with a cavity having fluid contents therein, and a paddle extends through the opening and into the fluid. A flexible seal extends from the opening in the enclosure and supports the paddle in the fluid. The flexible seal functions as a variable pivot for controlling the pivotal movement of the paddle within the cavity. The arrangement is such that the damper enclosure can be fastened to a base of the lever mechanism and the free end of the paddle is attached to the lever mechanism so that the pivot axis of the lever mechanism extends through the flexible seal, wherein the paddle, in response to the movement of the lever mechanism, pivots about the pivot axis of the lever mechanism since the damper mechanism is a sealed unit, it can be used in any orientation. The mass of the paddle can be selected and the center of gravity located relative to the pivot axis so that a static balance of the lever mechanism can be achieved wherein the operation of the entire transducer is sensitive to position or orientation.</p> |
