Title:
CYLINDRICAL LIQUID SEAL VIBRATION ISOLATOR AND ITS MANUFACTURE
Document Type and Number:
Japanese Patent JP3140816
Kind Code:
B2
Abstract:
PURPOSE: To acquire sufficient damping effect by depressing inward the cylindrical wall part of a middle cylindrical body facing to a plural number of liquid cells communicated through to each other through an orifice passage, forming a partition wall to partition the liquid cells in two of an inner peripheral side and an outer peripheral side and forming an orifice hole thereon.
CONSTITUTION: An inner cylindrical body 1 is connected to a vibration input side and an outer cylindrical body 5 is connected to a car body side, arid the radial direction to connect two liquid cells 6 With each other is arranged in the main vibrational direction. When vibration is input in the inner cylindrical body 1, an elastic body 3 is deformed and the inner cylindrical body 1 is moved in the radial direction relatively the outer cylindrical body 5, one side liquid cell 6a is contracted, the other side liquid cell 6a is expanded, liquid 7 flows to a liquid cell part 6b through the orifice hole 4d of a partition wall 4c from the liquid cell part 6a, then flows to the other liquid cell part 6b through an orifice passage 8b from the liquid cell part 6b, and then the fluid 7 flows to the liquid cell part 6a through the orifice hole 4d of the other liquid cell 6. At the time of flowing, as the liquid 7 receives flow resistance by the orifice passage 8b and the orifice hole 4d, it is possible to sufficiently carry out absorption and damping of vibration.
