Title:
FLUID-FILLED ANTI-VIBRATION APPARATUS AND AUTOMOBILE ENGINE MOUNT CONTROL METHOD USING SAME
Document Type and Number:
WIPO Patent Application WO/2010/001523
Kind Code:
A1
Abstract:
Provided is a fluid-filled anti-vibration apparatus with a novel structure that can realize effective anti-vibration effects against vibration input over a wide frequency range and that has excellent reliability and durability. A partition member (48) comprises an inside orifice member (52) fit into an outside orifice member (50) in a manner enabling relative displacement in the axial direction. An orifice passage (80) is also formed by forming an orifice-forming window (66) extending in the circumferential direction in either of the two faces of the outside orifice member (50) and the inside orifice member (52) that are fit together, and by partially covering the orifice-forming window (66) by the other, either the outside orifice member (50) or the inside orifice member (52). The covered part of the orifice-forming window (66) can be changed in the circumferential direction by relative displacement in the axial direction between the outside orifice member (50) and the inside orifice member (52), and the length of the orifice passage (80) can be changed as the covered part of the orifice-forming window (66) is changed.
