Abstract
A vibration preventing apparatus using fluid includes a main and an auxiliary fluid chamber in which fluid is confined. The main and auxiliary fluid chambers are communicated to each other by three kinds of orifices which exert different degrees of resistance to the flow of fluid. Two of such orifices which are smaller in resistance than the other are opened and closed independently of each other. The main fluid chamber is partly defined by an elastic member which supports a vibrating body. On vibration of the vibrating member, the volume of the main fluid chamber is varied to displace the fluid through any of the orifices. The particular orifices through which the fluid is to flow are determined based on the instantaneous vibration, whereby the vibration is absorbed effectively.
