Document Type and Number:
Japanese Patent JP2598987
Kind Code:
B2
Abstract:
In a mounting apparatus of the type wherein various vibrations over a wide frequency range are inputted, such as a mounting apparatus of a car engine, low kinetic spring characteristics for the input vibration of medium to high frequency ranges must be accomplished while securing high damping characteristics for the input vibrations of a low frequency range. In the present invention, a pressure receiving member (38) and a variable capacity balancing chamber (40) which communicate with each other through an orifice passage (46), into which pre-determined non-compressible fluid is sealed, respectively, and to which vibrations are inputted, are disposed between first and second support members (10 and 14) connected flexibly with each other by a rubber elastic member (26). A moving member (54) is stored movably in the pressure receiving chamber (38) and support means is disposed in order to prevent adhesion of the moving member (54) to the inner surface of the pressure receiving chamber (38) to define a vibration operation portion having a predetermined gap where fluidization of a fluid is generated around the moving member (54) at the time of the input of vibrations. In the mounting apparatus of the present invention, a high damping effect on the input vibrations of the low frequency range is exhibited by the resonance action of the fluid fluidized inside the orifice passage (46) and the low kinetic spring effect can be exhibited on the input vibrations of the medium to high frequency ranges by the resonance action of the fluid fluidized in the vibration operation portion defined around the moving member (54).
