摘要： In a hydraulic antivibration device for use in supporting a vibratory body like an automobile engine, the invention enables it to enhance the dimensional precision of an orifice for shake vibration, to decrease the dispersion in characteristics, and to reduce the dynamic spring rate in a high frequency region thereby reducing noise such as muffled sound. Its expedient is in that a main liquid chamber (6) and a first subsidiary liquid chamber (7) are mutually brought into communication through a first orifice (8), a partition element (10) comprises a partition plate member (11) including an elastic membrane (12) and an orifice member (13), the first orifice (8) is formed by outer circumferences of the orifice member and partition plate member and a cylindrical rubber portion (4a) linking to a diaphragm, a space enclosed by a central plate section (13a) of the orifice member and the elastic membrane (12) is formed as a second subsidiary liquid chamber (15), and an opening as a second orifice (16) for muffled sound communicating from the first (7) to the second liquid chamber (15) is formed in the central plate section (13a).

摘要： A liquid-in vibration isolator has an orifice hole mainly for audible sound provided on a first sub-liquid chamber and connected to a second sub-liquid chamber. When the first sub-liquid chamber is reduced to lower pressure and contracted due to large downward displacement caused by vibration and the diaphragm of the vibration isolator approaches the partition portion of the vibration isolator, the center plate portion of the orifice member is a convex with the center portion projected to the first sub-liquid chamber side, and the orifice hole is provided at a low portion of the center plate portion disposed eccentrically with respect to the isolator axis. Therefore, even being in contact with the center plate portion, the diaphragm hardly comes into contact with the orifice hole, or if it comes into contact with the orifice hole, it does not cover the orifice hole so as to interfere with proper function of the orifice hole.

摘要： A liquid-in vibration-isolating device, used to support a vibration generating source such as a vehicle engine for the purpose of vibration isolation, prevents hitting sound or adsorption of a diaphragm due to abutment against a partition member and proper functioning of the device is maintained, without increasing the volume of sub-liquid chamber on the diaphragm side. The device includes a cylindrical body fitting and a boss fitting connected via a vibration isolating substrate. A diaphragm is provided on an opening portion at the upper extremity, being partitioned into a main liquid chamber on the vibration isolating substrate side and a sub-liquid chamber on the diaphragm side by means of a partition member. Both liquid chambers are connected through an orifice of the outer circumferential portion. Multiple convex portions are provided for restraining the diaphragm from abutting against the partition member.

摘要： There is provided a liquid enclosing type vibration isolating apparatus which reduces a number of members to be aligned and which simplifies the assembling procedure in liquid, so as to reduce assembling steps and production cost. A cylindrical rubber body has a reinforcing intermediate cylinder, a concave groove and a through hole to form an orifice passage. The cylindrical rubber body is formed integrated with a diaphragm at a lower end of the cylindrical rubber body. A partitioning member has, on its peripheral part, an orifice passage concave portion. A first assembling step is conducted in air wherein a partitioning member is fitted into the cylindrical rubber body, so as to form an air chamber between the diaphragm and the partitioning member, while aligning the through hole with the orifice passage concave portion. Subsequent assembling steps are conducted in liquid wherein the cylindrical rubber body is fitted into a cup-like casing fitting and the vibration isolating base body is fitted into the cylindrical rubber body to form upper and lower liquid chambers which communicate via the orifice passage.

摘要： Rubber burrs which are formed on a first molding product are set to the closer side of spaces of side surfaces. Therefore, when the first molding product is placed in a resin mold for a resin molding process, it is unnecessary to insert a rubber-burr portion in the resin mold at a predetermined position (at which protrusion rubber parts can be brought into tight contact with the resin mold for sealing). That is, the rubber burrs formed along the parting lines can be placed in a cavity of the resin mold. Therefore, since second rubber covering parts can be easily inserted in the resin mold at the predetermined positions and working time can be reduced, workability can be improved. Moreover, since the predetermined positions of the resin mold can be surely sealed by tight contact with the side faces, generation of resin burrs can be suppressed.

摘要： A hydraulic antivibration device arrangement capable of achieving a downsizing and weight reduction, and a reduction of booming noise by suppressing a reaction force to impingement upon stopper action is provided. By disposing a protuberant rubber portion 35 at an upper end of a main body member 2, its spacing distance from a roll center can be lengthened, the reaction force to impingement can be diminished, and input load to the main body member 2 can be diminished. Consequently, reduction of rigidity and strength required for respective components as well as enhancement of durability is possible, which permits to make the components thin-walled thereby making a hydraulic antivibration device arrangement 100 lightweight as a whole. Diminishing of such reaction force upon stopper action also enables vibrations input through a car body side bracket 120 to the body frame to be suppressed, thereby reducing the generation of booming noise.

摘要： A switched vibration isolator has an elastic base member fixed to a first fitting member, and a tubular member fixed the elastic base member. A partition device is disposed in the tubular member, and has an outer diameter, a first partition side opposing the elastic base member defining a main liquid chamber therebetween, and a second partition side opposite the first partition side. The partition device defines an orifice communicating with the main liquid chamber. A partition receiving plate has a diameter greater than an outer diameter of the partition device and the partition device is mounted thereon. A diaphragm is disposed opposing the partition receiving plate and defining an auxiliary liquid chamber communicated with the main liquid chamber via the orifice. The partition receiving plate and the diaphragm are fixed in place together by an end of the tubular member.
