ABSTRACT:
An oil type damper comprises a housing, a rotator formed of a hollow shaft and a braking disk, a flexible membrane, a toothed wheel secured to the leading end of the aforementioned hollow shaft, and oil introduced via the hollow shaft into the housing. Since the oil is introduced through the hollow shaft into the housing after the rotator and the flexible membrane have been set in place inside the housing, the work of filling the damper with oil is easy. The flexible membrane absorbs thermal expansion of the oil and precludes otherwise possible oil leakage.
