A placing table includes a measuring-unit that measures a vertical position of an orifice member placed on the placing table, a position-regulating-portion that engages with a part of the orifice member of a type corresponding to the table, and an orifice-member-determination-unit that determines a placed state and type of the orifice member based on a measurement result obtained by the measuring-unit. When the corresponding type of the orifice member is placed in a correct posture, the position-regulating-portion engages with the orifice member and seats the orifice member on the table over the entire circumference of the lower end portion thereof. When a different type of orifice member is placed or when the corresponding type of orifice member is placed in an incorrect posture, the position-regulating-portion does not engage with the orifice member and lifts at least a part of the orifice member from the table.

Provided is an active engine mount having a vent hole that includes a damper assembly including an exciter. The damper assembly in the active engine mount which controls pressure of a main chamber as the exciter is excited has a vent hole that enables communication from a lower part of the exciter to the outside formed thereon such that air inside the damper assembly can be discharged to the outside.

A fluid-sealed engine mount may include an insulator integrally formed on an external side of a mount core configured to be coupled to an engine and having a chamber with which fluid for insulation of vibration is sealed; an orifice module mounted below the mount core to divide the chamber into two chambers and having a fluid passage for flow of the fluid; an air chamber provided at a center portion of the orifice module and filled with air; and an elastic membrane mounted above the air chamber at the center portion of the orifice module to seal the air chamber airtightly.

An engine mount includes a nozzle plate mounted between an insulator and a diaphragm so as to divide an interior into an upper liquid chamber and a lower liquid chamber, and an annular flow path formed in the nozzle plate so that an encapsulated hydraulic liquid flows between the upper liquid chamber and the lower liquid chamber, the nozzle plate being opened at an upper side of the flow path; a shielding member which has two or more shielding plates arranged to cover the upper side of the flow path; an adjusting bolt which is rotatably mounted in a core coupled to the insulator; and a connector, in which the shielding plates are folded or unfolded in accordance with a rotation of the adjusting bolt, and a size of an upper flow path hole is determined depending on a state in which the shielding plates are folded or unfolded.

A liquid-sealed vibration damping device is provided that allows an outer cylindrical member to have a substantially uniform interference margin in the circumferential direction, while improving an assembling property. A second mounting member mounted on a non-vibration source includes: a first frame in a cylindrical shape that is connected to a lower portion of an insulator; a second frame in a cylindrical shape that holds a partition member arranged below the insulator; and a connector that connects the first frame with the second frame. The connector includes: engaging parts that are arranged on the first frame; and elastic hook parts that are arranged on the second frame. The elastic hook parts are arranged at intervals on each of main frame parts in the circumferential direction thereof, and the elastic hook parts arranged on corners have lower rigidity than those arranged on the main frame parts.

An anti-vibration device including first and second rigid strength members interconnected by an elastomer body, the first strength member includes a base and at least three branches extending from the base along a first direction toward the second strength member, the three branches including two external branches and one central branch. The second strength member includes a transversal portion and at least two branches extending along the first direction from the transversal portion, respectively between the external branches and the central branch of the first strength member. The elastomer body extends transversally to the first direction between the external branches of the first strength member and has four legs extending respectively between the branches of the first strength member and the branches of the second strength member.

A hydromount suitable for mounting a motor vehicle engine on a vehicle body includes: a load-supporting spring that supports a mount core, encloses a working chamber, and is supported on an outer ring, an intermediate plate, and a compensation chamber separated from the working chamber by the intermediate plate and delimited by a compensation diaphragm. The compensation chamber and the working chamber are filled with a damping liquid and are connected with each other in a liquid-conducting manner via a damping channel disposed in the intermediate plate. The intermediate plate may include an upper nozzle disk, a lower nozzle disk, and a diaphragm disposed between the upper nozzle disk and the lower nozzle disk. The diaphragm may have an inner circumference, an outer circumference, and at least one valve opening. The at least one valve opening may be disposed completely between the inner circumference and the outer circumference.

A vibration damping device including: a first mounting member including a fitting tube part opening to a side for fitting and mounting of an inner bracket; a second mounting member; a main rubber elastic body elastically connecting the first and second mounting members; and a stopper rubber provided on a portion of a circumference of the fitting tube part while projecting to the side from an opening end surface of the fitting tube part, the stopper rubber being configured to overlap the inner bracket. The stopper rubber is configured to be elastically deformed by fitting and mounting of the inner bracket into the fitting tube part so as to abut and overlap the inner bracket in a state urged by an elasticity of the stopper rubber itself.

A vehicle includes an electric machine, an engine, an engine mount, and a controller. The engine has a base speed that corresponds to a speed of the electric machine and an engine power demand. The engine mount is disposed between the engine and a vehicle structure such as a frame or unibody. The controller is configured to, in response to compression of the engine mount, increase an engine speed to a value that is greater than the base speed to reduce engine lugging.

A mount apparatus that achieves both space saving and weight saving and is excellent in fatigue strength, is provided. The mount apparatus comprises a pair of attachment parts to be attached to a car body, a vibration receiving part, fixed to the attachment parts, for receiving input vibrations from a vibration source through an elastic material, and a dropout prevention plate supporting the vibration receiving part, the attachment parts and the vibration receiving part being made of resin, wherein the dropout prevention plate is arranged so as to cover an outer surface of the vibration receiving part at a predetermined interval from the outer surface of the vibration receiving part, wherein both ends of the dropout prevention plate is fixed through the pair of attachment parts to the car body.
