摘要： A fluid-damping vibration-isolating support device comprising a main support body having a rubber base member and a closed enclosure internally thereof; and a partition plate dividing the enclosure into two chambers which intercommunicate through an orifice and are filled with a liquid. The partition plate comprises a separator member and a stopper member. The separator member is formed of an outer peripheral thick wall portion having an orifice and an inner thin flat plate portion having at least one through-hole. The stopper member has two opposed plate sections provided so as to cover the through-hole and is captured to the separator member slightly movably to the degree that the plate sections are in contact with or separate from both faces of the flat plate portion. The stopper member serves to close upon low frequency vibration and open upon high frequency vibration, so that in the high frequency region rise of hydraulic pressure can be suppressed and dynamic spring rate can be lowered.

摘要： This invention relates to multiple mounting vibration-preventing device wherein a partition wall is interposed between an upper plate and a lower plate. An upper vibration-preventing rubber member is interposed between the partition wall and the upper plate so as to define an upper damper liquid chamber therebetween. A lower vibration-preventing rubber member is interposed between the partition wall and the lower plate so as to define a lower damper liquid chamber therebetween. The upper damper liquid chamber communicates with the lower damper liquid chamber through an orifice. An upper elastic film, disposed inside the upper vibration-preventing rubber member, has a portion spliced to the partition wall and its outer end part caulked to the upper plate. The upper damper liquid chamber is defined by the upper vibration-preventing rubber member and the upper elastic film. A lower elastic film, disposed inside the lower vibration-preventing rubber member, has a portion spliced to the partition wall and an outer end part caulked to the lower plate. The lower damper liquid chamber is defined by the lower vibration-preventing rubber member and the lower elastic film.

摘要： A rubber vibration insulator comprising a boss member as one fitting, a tubular body, an annular elastic member interposed between the boss member and one end of the tubular body, a plate member as the other fitting surrounding fixedly the opposite end of the tubular body, thus forming together with the aforesaid elements a sealed chamber having variable volume, and a capsule housed in the sealed chamber, in which a damping liquid is filled. The capsule comprises an external shell consisting of a rubber plate having an orifice and a plate body joined together and a diaphragm disposed transversely in the shell, thereby dividing its internal chamber into an air sub-chamber on the rubber plate side and a liquid sub-chamber on the plate body side. The rubber plate of the shell may be defined with recesses on both sides in a vertical symmetry and dispersedly to form thin film portions or be in the form of a thin rubber plate which is interposed between two porous plates at a clearance and play between them. With the arrangement of the capsule, the spring rate of the diaphragm can be lessened and the liquid pressure in the sealed chamber can be prevented from rising in the high frequency region. Thus, muffled sounds and transmission sounds are insulated.

摘要： The present invention provides a liquid enclosing type vibration isolating mount comprising a vibration isolating base member 16, a diaphragm 20 and a partition member 22 for vertically dividing a space between the former two into upper and lower liquid chambers 24 and 26. The partition member 22 is made of a press worked metal plate which is held in contact with the periphery of the diaphragm 20 to provide an orifice path 28 for establishing communication between the liquid chambers 24 and 26. The vibration isolating mount of the present invention has the following advantages: The partition member 22 is made of a press worked metal plate so that the manufacturing cost can be saved; since the periphery of the diaphragm 20 is used as a part of the wall of the orifice path 28, the axial length of the mount can be shortened and the shape of the mount is simplified; and the pressing process of the partition member 22 is facilitated.

摘要： A liquid-sealed body mount comprising an inner and an outer cylinders concentrically disposed, a first and a second rubber members provided mutually in axially spaced relation and connecting both cylinders therebetween, an intermediate rubber plate means partitioning axially an enclosure surrounded by both cylinders and both rubber members into a first and a second liquid chambers, an orifice for communication with both chambers apertured in the intermediate means, and a liquid filled in both chambers. The intermediate rubber plate means is configured, when assembled, so as to be preliminarily deformed in the shearing direction, assuming a shade-like form and, when imposed with a prescribed load, so as to retain a neutral state of intersecting orthogonally both cylinders, whereby equalized vibration-preventing characteristics against oscillations on both bound and rebound sides are achieved.

The first liquid chamber has a first liquid chamber wall formed at least in part by the vibration isolating base body, the partition and the rigid tubular fitting. The second liquid chamber has a second liquid chamber wall formed at least in part by the diaphragm and the partition. The partition defines an orifice communicating the first and the second liquid chambers with each other. The rigid tubular fitting forms at least a portion of a side wall of the first liquid chamber wall and defines at least one opening in the side wall. An elastic membrane cup covers each of the at least one side wall opening and has a convex surface projecting into the first liquid chamber and a concave surface defining an air chamber separated from the first liquid chamber by the elastic membrane cup and extending into the interior fitting cavity. The air chamber may be sealed or open to the atmosphere.
