摘要:
Arrangement for the gas-tight fixing of an inlet manifold (1) with a connector flange to the cylinder head (2) of an internal combustion engine, with a sealing plate (3), arranged between the connector flange of the inlet manifold (1) and the cylinder head (2), in which at least one air passage (4, 5, 6, 7) for the at least one inlet tube of the inlet manifold (1) is embodied, with first connecting means (9) for connecting the sealing plate (3) to the inlet manifold (1), which are arranged in housings (10), in or on the sealing plate (3), with second connecting means for connecting the connector flange (1) and/or the sealing plate (3) to the cylinder head (2). A first sealing means (19) is provided on the sealing plate (3) on the one side (18) thereof, surrounding the at least one air passage (4, 5, 6, 7), for fitting to the inlet manifold (1), whereby at least one elastic element (13) is provided between the first connecting means (9) and the sealing plate (3).

An acoustic barrier systems that reduces the amount of noise entering the passenger compartment of a vehicle includes a secondary acoustic attenuator that extends from a primary acoustic barrier to a vehicle component case to envelop space around a conduit passing from the engine compartment to the component case. In one embodiment, the secondary acoustic attenuator extends from the primary acoustic barrier to the component case, with the secondary acoustic attenuator enveloping space around the conduit between the vehicle component case and the primary acoustic barrier. In another embodiment, the secondary acoustic attenuator is hingedly connected to the primary acoustic barrier to allow the secondary acoustic attenuator to be pivoted, from an orientation that allows installation of the vehicle component case, to another orientation wherein the secondary acoustic attenuator engages the vehicle component case to envelop space around the conduit between the vehicle component case and the primary acoustic barrier.

The damper assembly includes a centering spring about a bearing for a rotating shaft. The centering spring is fixed to and spaced from a fixed component. One or more annular arrays of brush bristles project from the fixed component and have tips in engagement with the non-rotating, radially and orbitally movable centering spring. With the brush bristles engaging the centering spring, the vibrations and dynamic loadings of the shaft on the bearing and centering spring are damped.

A liquid-sealed mount capable of obtaining excellent damping performance is provided. For this purpose, the mount includes an elastic body (16), a stud (13) penetrating through the elastic body, a case (51), which is in a cylindrical shape with one end side being opened and with a bottom face on the other end side, and houses a viscous liquid (L) inside, and in which the viscous liquid is scaled by fitting the elastic body and the stud into the opening at the one end side, a damping member (14) attached to the stud in a state in which the damping member submerges in the viscous liquid; and a wall surface of a portion of the case, which submerges in the viscous liquid, is formed so that an inner diameter gradually decreases toward a lower position and an angle of inclination is different in an upper part from a lower part; and an outer circumferential side surface of the damping member opposes the inclined surface of the case.
摘要:
The sealing ring seals between relatively rotating and vibrating machine parts such as parts of an aircraft propeller, and has several sealing lands. The shape and configuration of the lands are selected so that natural vibration frequencies of the ring or lands are not vibration frequencies to which the ring is subject in use.
