Title:
VIBRATION CONTROLLER OF CONSTRUCTION
Document Type and Number:
Japanese Patent JPH04222779
Kind Code:
A
Abstract:

PURPOSE: To perform periodical adjustment of a fluid type vibration controller with high degree of accuracy and, at the same time, to control energy consumption as much as possible.

CONSTITUTION: A gas connection way 24 connecting upper spaces 20 and 22 of a pair of fluid storage tanks 14 and 16 is separated with a partition plate 26 movably by air-tight construction. Energizing force of a plate spring 32 is applied on the partition plate 26 through a rod 30. The energizing force of the plate spring 32 is variable by moving a slider 34 up and down with an actuator 36. According to the constitution, resistance caused by the plate spring is provided to gas passing through the gas connection way by the generation of vibration, and a moving period of fluid passing through a fluid connection way 18 can be controlled with high degree of accuracy. The actuator is not used every time, so that energy consumption is reduced.
