摘要： PURPOSE:To enable good vibration damping to be effected in the case of both high and low frequency bands by providing vibration members displaceable according to a difference in the internal pressure between both liquid chambers, in a through hole open to both liquid chambers. Which are separated from each other at an interval in the peripheral direction through stoppers. CONSTITUTION:Two liquid chambers 5, 6, which are separated from each other in diametrically facing state and filled with incompressible liquid having necessary kinematic viscosity, are provided at the central position in the axis direction of an elastic body 3 between an inner and an outer cylinders 1, 2 in order to be reciprocally communicated by a throttle passage 8. Also, a through hole 11, which opens to the respective liquid chambers 5, 6 through stoppers 9, 10 projected inside the liquid chambers 5, 6, outward in the radial direction is provided in order to be closed at its both end parts by flexible membrane bodies 12, 13 as an example of vibration member.

摘要： PURPOSE:To absorb vibration in the different directions by providing a vibration absorbing element which is deformed by contact with the inner and outer cylinders to absorb vibration in a hollow chamber disposed in a part of an elastic body connecting the inner and outer cylinders. CONSTITUTION:An inner cylinder 12 and an outer cylinder 14 disposed coaxially are connected to each other by elastic bodies 16. A hollow chamber 20 is formed between a pair of elastic bodies between the inner cylinder 12 and the outer cylinder 14. The hollow chamber 20 is formed between a pair of elastic bodies between the inner cylinder 12 and the outer cylinder 14. The hollow chamber 20 may be an air chamber, or other fluids such as water or the like may be sealed therein. A flexible bag 22 is disposed in the hollow chamber 20. The flexible bag 22 is ring-shaped and disposed in the periphery of the inner cylinder 12. The flexible bag is circular in section and formed by flexible material, and a high-viscosity fluid is sealed in the bag. Thus, a vibration absorbing element is formed.

摘要： PURPOSE:To obtain a peak of damping force in plural vibration frequencies, by forming a diameter of a communication port in a fluid chamber, which communicates with an expansible-contractible fluid chamber, with the atmosphere to be set smaller than the diameter of a communication port from the expansible-contractible fluid chamber. CONSTITUTION:A vibro-isolating device 10 provides on its base plate 12 a cylindrical elastic member 14, which forms the first expansible-contractible fluid chamber 18, to be set between the plate 12 and a top plate 16. And the device forms the second fluid chamber 24 by an end wall between the base plate 12 and a bolt plate 22. The device forms a diameter of the first opening 28, through which the first and the second both fluid chambers 18, 24 communicate, to be set larger than the diameter of the second opening 30 causing the second fluid chamber 24 to communicate with the atmosphere. Consequently, the device 10, in which a vibration frequency stopping a flow of fluid passing through the both openings 28, 30 comes to be different, obtains a peak of damping force in plural vibration frequencies.

摘要： PURPOSE:To improve damping effect by increasing moving air quantity by forming plural air chambers by disposing an elastic inner member in an outer member and by expanding and contracting the plural air chambers to opposite directions by displacement of the inner member at time time of generation of vibration. CONSTITUTION:An outer elastic body 14 which is an outer member is fixed to peripheral edge of a bottom member 10 and its upper portion is formed slim and connected to a shaft 20 which is a head member. And an air chamber is formed in the outer elastic body and an elastic inner member 24 connected to the bottom member 10 and a head member is disposed in the air chamber to section the chamber into plural small air chambers 26, 28. Respective small air chambers 26, 28 are communicated to outside or mutually through limit passages 30, 32, and they are expanded or contracted to opposite directions by displacement of the elastic inner member 24, and large moving air quantity can be obtained.

摘要： PURPOSE:To reduce change in characteristics due to temperature by forming a pair of air chambers communicating to the atmosphere through an orifice between inside and outside members to provide a vibration preventing action through air entering and exiting said chambers. CONSTITUTION:A cylindrical hollow elastic body 16 is disposed inside an outer ring 10, and an inner ring 12 extends through the axial portions of the top and bottom plates 16A, 16B of the hollow elastic body 16. The hollow elastic body 16 is formed in the interior with a hollow chamber which is defined by a partition wall 20 extending radially of the inner ring 12 to provide a pair of air chambers 22, 24. The air chambers 22, 24 communicate to the atmosphere through orifices 26 extending through the outer ring 10 respectively. Since the air chambers 22, 24 thus communicate to the atmosphere, change in characteristics due to temperature difference can be restrained.

摘要： PURPOSE:To absorb vibration by inserting a pipe having a small effective area into a hollow chamber and installing a rotary body which is revolved by the flow of the fluid in the pipe and properly generating resonance having an arbitrary frequency even in the case when the axial length of the pipe member is short. CONSTITUTION:One edge of a pipe member 22 is inserted into a base plate 12, and the other edge of the pipe member 22 is opened to the atmosphere. A rotary body 24 is arranged inside the pipe member 22 so as to be shifted in the longitudinal direction of the pipe member 22. The shift amount in the longitudinal direction of the rotary body 24 is regulated by the stoppers 25A and 25B projecting in the direction for reducing the inside diameter towards the inside of the pipe member 22. With such constitution, vibration is applied onto an elastic member 16 through a top plate 14, and gas-column resonance is generated on the pipe member 22, and said vibration can be effectively absorbed by the rotary body 24.
