Title:
LIQUID-IN VIBRATION ISOLATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2002/016799
Kind Code:
A1
Abstract:
A liquid-in vibration isolating device wherein a cylindrical main body metal fitting (1) and an attaching metal fitting (2) are joined through a vibration isolating base (3), an inner chamber surrounded by a diaphragm (4) disposed at the upper end and by the vibration isolating base (3) is partitioned into a main liquid chamber (6) and a first auxiliary liquid chamber (7) by a partitioning section (10), a first orifice (8) is installed in the outer periphery of the partitioning section (10) for establishing communication between the main liquid chamber (6) and the first auxiliary liquid chamber (7), the partitioning section (10) being composed of a partitioning plate member (11) having an elastic membrane (12) and an orifice member (13), the space between the central plate portion (13b) of the orifice member (13) and the elastic membrane (12) serving as a second auxiliary liquid chamber (15), the central plate portion (13b) being raised toward the first auxiliary liquid chamber (7), an orifice hole (16) leading from the first auxiliary liquid chamber (7) to the second auxiliary liquid chamber (15) is formed in the low region of the central plate portion (13b) in off-center relationship to the axis of the device, it being arranged that the diaphragm (4) does not close the orifice hole (16), satisfactorily maintaining the function.
