In the liquid filled type vibration isolator comprising a rubber-like insulator for absorbing and isolating vibration transmitted from an oscillating body, a main chamber having a chamber wall formed by a part of the insulator, and hermetically charged therein with liquid, an auxiliary chamber connected to the main chamber through the intermediary of an orifice and having a chamber wall a part of which is formed by a first diaphragm, a partition member partitioning between the main chamber and the auxiliary chamber, a working chamber defined and formed with respect to the main chamber by means of a second diaphragm, wherein the second diaphragm has a deforming stiffness which is higher than that of the first diaphragm. The liquid in the orifice effects resonant oscillation with a vibration input during engine idling operation.

摘要： A hydraulic damping device including a main damping body protected by a cylindrical portion with downwardly extending side walls. The damping device includes a flexible membrane which has a step portion, a main liquid chamber, an auxiliary liquid chamber and a partition formed in a cup-shape. A passage is made between the step portion of the flexible membrane and the interior of the partition. The partition divides the liquid chamber into a main liquid chamber and an auxiliary liquid chamber. The partition also includes a hole formed therein, a channel and a concave recess formed on the partition side wall between the hole and the channel. This structure permits the main liquid chamber to be connected to the auxiliary liquid chamber through the hole, the passage and the channel. The membrane is inserted into the interior of a cylindrical portion of the main damping body together with the partition and the damping liquid to define a simply constructed sub-assembly. This sub-assembly is subsequently easily inserted into the interior of a cylindrical portion of the supporting member by pressurized insertion.

摘要： In a fluid-filled vibration damping device, a rubber material is injection molded in the upper half of an inner space of a cylindrical insert plate 1 to form a damping rubber member 2 through which an inner tube 3 is retained. A concave 21 is formed in the center of the damping rubber member 2 in such a way that it extends from the periphery to a point close to the inner tube 3 such that both sidewalls thereof are left intact. The concave 21 provides a main fluid compartment A when the insert plate 1 is pressed and fixed in the outer tube. The insert plate 1 has a large concave in the lower half thereof and a plurality of openings are made in the sidewall of the concave 12 except for the bottom wall 121 thereof. A rubber layer 5, injection molded in the concave, has a central part of its width left intact in block form and part of this rubber layer provides a thin rubber wall that covers the openings in the sidewall of the concave 12 which face a cavity 53. When the insert plate 1 is pressed and fixed in the outer tube 4, a sub-fluid compartment B is formed between the outer tube 4 and the thin rubber wall which serves as a defining wall of the compartment B, and this compartment communicates with the main fluid compartment A via a flow constricting channel F around the insert plate 1.
