・ダンピング特性が悪化する不都合を伴う。Conventionally, this type of mount has a liquid chamber on the lower surface of the mount body that is divided into two upper and lower chambers by a partition plate having a small hole, and the liquid inside the liquid chamber is drawn through the small hole by the expansion and contraction of the mount body. It is known that vibrations are absorbed by the dynamic damper effect caused by the flow of liquid.
If this product is used for a long period of time, the cause is unknown, but bubbles are generated from the liquid sealed in the liquid chamber, and these bubbles can adversely affect the dynamic damper effect and reduce the elasticity of the gas that accumulates in the upper part of the liquid chamber. This results in an increase in the dynamic spring constant and a deterioration of the damping characteristics.

せるようにした。Referring to FIG. 1, (1) shows a mount body which is made up of a substantially conical rubber body and a seat metal fitting (2) which serves as a mounting seat for an engine, etc. is fixed to the top of the mount main body (4). )
is fixed to form a liquid chamber (5) for sealing liquid such as oil on the lower surface of the mount body (1), and the liquid chamber (5) is connected to an intermediate partition plate integral with the mounting bracket (3). (6), it is divided into two upper and lower chambers, and these compartments are communicated with each other through a small hole (7) in the center formed in the partition plate (6), and the mount body ( The expansion and contraction displacement of 1) causes a flow of liquid through the small hole (7) in the liquid chamber (51), and the resulting dynamic damper effect absorbs vibrations.

くその上部に弾性要素たる気体（８＆）を残した。Therefore, according to the present invention, a bubble absorption chamber (8) containing gas or other elastic elements is provided in the mount body (1), and the absorption chamber (8) is connected to the liquid chamber (5) through an orifice (9). The bubbles generated in the liquid chamber (5) are communicated with the absorption chamber (8).
) so that it can be absorbed by To explain this in more detail, in the one shown in the first figure, a concave hole opening into the liquid chamber (5) is formed in the receiving metal fitting (2) at the top of the mount body (1),
A cap (10) with a small hole in the center of the orifice (9) is attached to the opening, and the upper concave hole portion of the cap Ql is configured as the absorption chamber (8). )
The liquid filling the liquid chamber (5) did not replace the metal part, leaving the gas (8&) as an elastic element above the metal part.

。Next, to explain its operation, when bubbles a are generated in the liquid M (5) as shown in the second figure, the mount body (1)
Bubbles a do not move in a state where no expansion or contraction occurs, but
A displacement in the compression direction is applied to the main body (1) to form a liquid chamber (5).
When the liquid pressure in the liquid chamber (5) increases, the liquid in the liquid chamber (5) flows into the absorption chamber (8) through the oriice (9) while compressing the gas (8a) in the upper part of the bubble absorption chamber (8). However, bubbles a are drawn into this liquid flow and flow into the absorption chamber (8).

ない。Here, the liquid in the liquid chamber (5) enters and exits the absorption chamber (8) via the oriice (9) only when the mount body (1) expands and contracts at a low frequency. , when the orifice (9) expands and contracts at a frequency higher than a certain level depending on the diameter and length of the orifice (9), almost no liquid flows through the orifice (9). Absorption chamber (8)
is substantially separated from the liquid chamber (5),
The elasticity of the gas flowed into and absorbed into the absorption chamber (8) hardly affects the dynamic characteristics, such as an increase in the dynamic spring constant.

である。In addition, when the mount main body (1) expands and contracts at a low frequency, the absorption chamber (8) accompanies the flow of liquid from the absorption chamber (8) toward the liquid chamber (5) upon displacement in the expansion direction. ) Some of the air bubbles that have flowed into the liquid chamber (5) may flow back to the liquid chamber (5), and to prevent this, a sheet-like or In order to suppress the movement of liquid or air bubbles in the chamber 1 provided with a spherical check valve ring or the absorption chamber (8), a foam material as shown in FIG. 5 or a foam material as shown in FIG. It is sufficient to fill the small ball α as shown in the above example.In addition, in the above example, the orifice (9
), but it is not limited to this; for example, the seventh
The orifice (9) may be constituted by a plurality of narrow grooves formed on the circumferential surface of the cap (10) as shown in FIGS. It is also possible to construct a long orifice (9) with a spiral groove on the circumferential surface.
