摘要： A multiple chamber piston includes a first fluid chamber and a second fluid chamber attached by a first channel and a third fluid chamber connected to a fourth fluid chamber by a second channel. Air chambers are provided between the first fluid chamber and the third fluid chamber as well as the second fluid chamber and the fourth fluid chamber. As a result, when vibration is to be attenuated, walls of the air chambers are able to bend and deform to increase compliance of the overall multiple chamber piston.

摘要： A restrictive fluid passageway is defined between an outer sleeve and a bracket to provide fluid communication between a working chamber and a compensation chamber or two compensation chambers. In one embodiment, two compensating chambers are arranged outside of the outer sleeve. In another embodiment, one compensation chamber is arranged within the outer sleeve, and the outer sleeve is constituted by axially separated three sections, i.e., first and second sleeve sections and a spacer section interposed between the first and second sleeve sections. A resilient deformable member and flexible wall member has a pair of axially spaced sealing lips projecting outward from an outer circumferential surface. The sealing lips are interposed between matched ends of the first and second sleeve sections and the spacer section and sealingly contact an inner circumferential surface of the bracket.

摘要： A power unit mount through which a power unit is supported on a vehicle body in a manner to insulate vibration transmission. The power unit mount is comprised of an elastomeric support body fixedly interposed between inner and outer cylindrical members which are connected respectively to the vehicle body and the power unit. The elastomeric support body is formed with a hollow defining a main fluid chamber. An elastomeric diaphragm is provided to define an auxiliary fluid chamber which is communicable with the main fluid chamber through first and second orifice passages which extend along the inner periphery of the outer cylindrical member. Liquid fills the main and auxiliary fluid chambers and the orifice passages. In the first orifice passages, the resonance point of the liquid is tuned to increase the loss factor of the power unit mount in response to relatively low frequency vibration, thereby dampening engine shake. In the second orifice passage, the resonance point of the liquid is tuned to lower the dynamic spring constant of the power unit mount in response to relatively high frequency vibration, thereby dampening idling vibration of the power unit. Additionally, a movable plate arrangement is disposed in the second orifice passage and adapted to close the orifice passage in response to the relatively low frequency vibration, thereby permitting fluid passage through only the first orifice passage during input of the relatively low frequency vibration.

摘要： An elastomer bush bearing with hydraulic damping, which is simultaneously configured for acoustic decoupling. The proposed hydro-bush bearing includes, in a conventional manner, a tubular metallic inner part (1) and an elastomer bearing body (2) which encompasses the inner part (1) and is connected with the inner part (1) by vulcanization. The corresponding rubber-metal part is formed of metal or plastic and adapted for insertion into an outer sleeve. At least two chambers (3, 4) adapted to receive a liquid damping means are formed in the bearing body (2) and connected by a damping channel (5) which is open in an unloaded state. An additional channel (6) is arranged between the chambers (3, 4), which in the unloaded state of the bearing is closed for the damping means by a sealing lip (7). The sealing lip is constructed so as to oscillate with an amplitude in excess of 0.025 mm at high-frequency loads. In addition, support elements (8, 9) are arranged on both sides of the sealing lip (7) which limit the oscillation amplitude of the sealing lip (7) for loads which cause displacement amplitudes of the bearing body of greater than 0.15 mm.

摘要： A hydraulically damping rubber is provided with an uncoupling element. The bearing has an elastomer arranged between an essentially cylindrical inner part and a cylindrical outer sleeve and connected to the inner part by vulcanization. The hydraulically damping rubber bearing has chambers for receiving a damping agent. The chambers are connected by at least one channel arranged in a channel carrier. The uncoupling element is provided for uncoupling the damping action caused by the circulation of the damping agent in the channel or channels against forces of low exciting amplitude introduced into the bearing. The uncoupling element is a separate component from the hydraulically damping rubber bearing, arranged in a recess in a channel carrier space of the bearing. The uncoupling element includes a frame with a membrane fixed in a freely vibrating manner in or on the frame and a radial distance is assigned to the membrane between the channel carrier and the outer sleeve of the bearing, so that a radially directed movement of the membrane is possible.

摘要： A liquid-filled bearing having a hydraulic damping device and two fittings which surround one another and are joined by an elastic spring element of elastomer material, there being at least one movable partition wall disposed between two liquid-filled chambers. At least one of the fittings has a gap extending essentially parallel to a moving direction and open in the direction of at least one of the two chambers. The partition wall consists of elastomer material and joins together surfaces defining the gap as the result of a rolling-diaphragm-type profile.

摘要： A hydraulically damped rubber cartridge spring incorporates two chamber pairs (4, 6; 5, 7) isolated from one another by a wall (8 ). The chambers are located at a distance from one another in the direction of the introduced vibrations. The chambers of each chamber pair are connected by damping orifices (9, 10) of a channel-like configuration. The damping orifices (9, 10) are so dimensioned and coordinated with the bulge elasticity of the corresponding walls (11) of the bilaternally adjoining chambers, that the contained liquid mass enters into a resonant motion if the vibrations introduced by the spring's operation differ from one another in frequency. The dividing wall (8) contacts the external sleeve (1) loosely when vibrations are not introduced, and at the same time is resiliently deformed toward the internal tube (2) by the external sleeve (1).

摘要： A hydraulically damped mount includes both a fluid overflow opening (6) and a damping opening (5) arranged in parallel between a fluid working chamber (4) and an equalizing chamber (7). In the overflow opening (6) there is provided a pressure relief valve (8) which can be activated by the differential pressure between the working chamber and the equalizing chamber. This valve contains a control element (10) and an opposing counter stop (11) which the control element can contact with a tight fit and which it can pass by in case of excess pressure. When inactive, the control element (10) is spaced apart from the counter stop (11) at such a distance that a contact with the counter stop (11) is impossible when acoustically active vibrations are introduced.
