Isolated cover with independent sealing system

A vibration isolation or noise attenuation and fluid sealing system, for use in connection with internal combustion engine components. For example, for use in the mounting of a valve cover or rocker arm cover upon a cylinder block or cylinder head, or for the mounting of an oil pan cover upon an oil pan housing. The system has an isolation medium or member mechanically and/or chemically bonded to a peripheral flange portion of the cover member. A sealing flange member is chemically and/or mechanically bonded to the isolation member or medium. The three components being a one-piece unitary cover assembly. The fluid leakage along the interfaces defined between the three components is effectively eliminated. The one-piece assembly is secured to the cylinder block or head, or the oil pan housing, by shoulder bolt fasteners. The fasteners exert compressive forces upon the isolation member so as to vary the stiffness and frequency characteristics thereof. Thus, fine tuning of the stiffness can effectively absorb, dampen, and dissipate noise and vibration.

Noise and vibration suppressors

In order to form a noise suppressor in a hose of e.g. a motor vehicle, modular portions are connected in series to define suppression chambers with particular noise suppression characteristics. Those characteristics are due to the volume of each chamber, to the size of the apertures from the chambers to the central duct of the suppressor, and optionally due to spacers which are inserted into at least one aperture of the chambers to alter the effective open area of that aperture. Such spacers may also be used in which the noise suppressor is not modular. Where modular portions are used, it is preferable that each chamber is bounded by parts of two modular portions. A wall of one modular portion may then close the chamber in another modular portion, making the manufacture of the modular portions easier. Also disclosed is the use of a mass acting as a damper, which may be a noise suppressor as previously discussed, within a hose. The mass is connected to the hose by resilient means, e.g. electrometric material.

Component for an internal combustion engine

Admission device with a pipe section for damping the admission noise

The invention relates to an admission device, especially for use for an internal combustion engine, which has a pipe section for damping the admission noise. Damping devices of this type are needed for damping the noises caused by ancillary components in the admission device. In order to compensate the resulting additional complexity of the device as far as possible, the invention provides solutions permitting simple production procedures and flexible adjustment to the frequency bands to be damped. For example, in an admission pipe (10) consisting of welded shells (21, 22), the welding catching edge (27) can be used for separating a resonance volume (29) if the welding catching edges form a large enough gap. This measure means, e.g. that there is no extra need for structural components, only a slightly greater material requirement. Admission acoustics can also be improved retroactively using this measure by making small changes to the casting tools for the shells (21, 22).

The air cleaner case 30b is formed of a front wall 31, a rear fender 32, and right and left side covers 23. The upper opening 30c is closed by a seat 21. A sound absorbing member 50 is bonded to a bottom plate 33 of the seat 21 and housed in an air cleaner space 30a. The intake noise in the air cleaner 30 is absorbed by the sound absorbing member 50.
