Mechanical instrument's pipe fixation maintaining system, has bimetal whose reaction provokes displacement of stop device in direction opposite to dilatation direction such that length of air column in vibration remains constant

摘要

The system has two parts (A, B) moved with respect to each other and actuated by a bimetal (D). The reaction of the bimetal provokes displacement (E) of a stop device (C) in a direction opposite to a dilatation direction of a pipe of a mechanical instrument during temperature fluctuations such that the length of air column in vibration remains constant.
