摘要： A vibration-damping device including: an elastic body connecting a first and a second mounting member: a pressure receiving and equilibrium chambers partially defined by the elastic body and a flexible diaphragm, filled with a non-compressible fluid and held in fluid communication through a first orifice passage and a second orifice passage that is tuned higher than the first orifice passage. A shut-off valve mechanism operable to selectively allow and inhibit fluid flows through the second orifice passage, an elastic oscillation plate partially defining the pressure-receiving chamber so that a fluid pressure in the pressure-receiving chamber acts on one surface of the elastic oscillation plate, and a working air chamber partially defined by the other surface of the elastic oscillation plate and oscillated by a periodic air pressure change in the working air chamber, are also incorporated. A method of controlling the same is also disclosed.

摘要： A hydraulic antivibration sleeve comprising two constrictive strength members interconnected by an elastomer body which defines first and second diametrically opposite working chambers and a side compensation chamber. The two working chambers communicate with each other via a constricted passage, while the compensation chamber communicates with the first working chamber only via another constricted passage. The elastomer wall which defines the second working chamber is free and is not in contact with the inner strength member except in a certain range of values for the radial static load supported by the sleeve: this provides two different modes of operation depending on the value of said static load.

摘要： A liquid-filled vibration-proof device constructed so that the positioning and supporting function of a partition is performed firmly and a port opening of an orifice passage in the partition is not obstructed to ensure a sufficient opening area of the port opening. To that end, a diaphragm and a partition located inwardly thereof are hermetically fixed to a cylindrical fitting at a side opposing a vibration-isolating base thereby partitioning an enclosure between the vibration-isolating base and the diaphragm into two liquid chambers, the both liquid chambers being put in communication with each other through the orifice passage; the vibration-isolating base is provided at a marginal part of its inner face with protruding portions for positioning, with which an upper marginal portion of the partition is in opposed contact, disposed circumferentially at intervals at plural positions so as not to impede the flow of the port opening.

摘要： A bushing is disclosed with a sleeve. The sleeve member has an inner surface and a cavity. A core member is disposed in the cavity. A pair of elastomeric members are disposed in the cavity. One of the pair of elastomeric members is adjacent to the core. The other of the pair of elastomeric members is adjacent to the inner surface. The one of the pair of elastomeric members has a modulus that is greater than the other of the pair of elastomeric members so that one of said pair of elastomeric members absorbs low frequency vibration and the other of the pair of elastomeric members absorbs high frequency vibration.

摘要： Disclosed is a fluid-filled active vibration damping device including: an elastic body; a primary fluid chamber partially defined by the elastic body; a movable member partially defining the primary fluid chamber on one side and a working air chamber on the other side; and a vacuum pump including an air intake port and an exhaust port, which are connectable to the working chamber via a valve mechanism. A fluid pressure variation in the primary fluid chamber can be actively controlled by transmitting an air pressure variation in the working air chamber to the primary fluid chamber via the movable member. A switching operation of the valve mechanism selectively applies a negative pressure generated in the air intake port and a positive pressure generated in the exhaust port to the working air chamber in order to generate the air pressure variation in the working air chamber.

摘要： A double orifice type liquid-in vibration isolating device including a partition portion fitted between a vibration isolating substrate combined through a body fitting and a first diaphragm made up of a partition main member forming a first orifice, a partition plate member forming a second sub-liquid chamber and a second orifice, and a partition support plate forming the first orifice. An inlet/outlet on the main liquid chamber side of both orifices is common to both orifices. The first orifice is diverged from a part of the second orifice having a liquid passing resistance smaller than that of the first orifice to provide two orifices compactly. Any variation or change of the property can easily be coped with by circumferential position adjustment of the component members of the partition portion.

摘要： A liquid-sealed vibration-proof device capable of avoiding leakage of liquid upon press fitting of an outer cylinder is provided. An intermediate ring interposed between the outer cylinder and an antivibratory base is formed at its outer circumferential surface with two projecting streaks, the one on liquid chambers side being formed with cutouts. When the outer cylinder is press fitted to an attachment opening of a vehicle body, the liquid confined in a space enclosed between both projecting streaks can escape to the liquid chambers, so that liquid never leaks outside.

摘要： A shock absorber includes a piston assembly having a compression valve assembly and a rebound valve assembly. One of the valve assemblies includes a free floating port blocker disc disposed in a pressure chamber. The blocker disc allows for the low speed bleed flow of fluid in one direction but restricts the low speed bleed flow of fluid in the opposite direction.
