ABSTRACT:
In an accelerometer in which a proof mass is disposed in a damping fluid and acts against said fluid through a flow path controlled by the groove length of a helix disposed on a bellows, a low resistance flow path is provided connecting the areas above and below the helix to prevent movement of the proof mass due to fluid displacement caused by rapid temperature changes.
