Title:
LIQUID SEAL VIBRATION CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2002/016800
Kind Code:
A1
Abstract:
A liquid seal vibration control device capable of preventing an electrolytic corrosion of an intermediate fitting and an outer tube fitting due to adhesion of electrolyte thereto, providing an excellent sealing effect between both fittings, and maintaining a satisfactory vibrationproof characteristics, wherein a rubber elastic body forming an end part wall (13) is stuck, by vulcanization, on the outer peripheral surface of an inner tube fitting (11), the intermediate fitting (16) is stuck, by vulcanization, on the outer peripheral surface of the rubber elastic body, the rubber elastic body of the end part wall (13) is routed from at least one of the axial outside end and the inside end of both end cylindrical parts of the intermediate fitting (16) to the outer peripheral surface thereof, an inside unit is inserted into the outer tube fitting (12) so as to reduce the diameter of the outer tube fitting (12), the axial end part is caulked, a clearance between the caulked ends (12a) of the intermediate fitting (16) and outer tube fitting (12) is sealed by the extension part (17) of the rubber elastic body, and a clearance between the intermediate fitting (16) and the inner peripheral surface of the outer tube fitting (12) is sealed by the extension parts (17a) and (18a) routed to the outer peripheral surface, whereby a liquid leakage can be prevented.
