Abstract:
The invention relates to a silencer (1) and a method for manufacturing a silencer (1), in particular a vehicle silencer, having an inner pipe section (2) and at least one resonator chamber (14, 15) embodied outside the pipe section (2), with the shell (3) of the pipe section (2) having at least one opening (7, 8) that connects the interior of the pipe section (2) with the resonator chamber (14, 15). For simplifying the production process as well as for material and weight savings, the shell segments (4, 5, 6) are prefabricated as individual components and the shell of the inner pipe section (2) is formed by assembling the prefabricated shell segments (4, 5, 6), with the shell segments (4, 5, 6) being arranged to be spread along the circumference of the pipe and extend in axial direction from a first connecting piece (11) to a second connecting piece (12) each, and first ends (9) of the shell segments (4, 5, 6) are connected with the first connecting piece (11) and second ends (10) of the shell segments (4, 5, 6), lying opposite the first ends (9), being connected with the second connecting piece (12).
Abstract:
An intake manifold is disclosed which has an upper shell portion having a first peripheral flange, a lower shell portion having a second peripheral flange, and at least one metallic post having a first plate and a second plate. The first and second peripheral flanges are friction welded and the first plate of the posts is friction welded to the upper shell portion and the second plate of the posts is friction welded to the lower shell portion. The upper and lower shells are made of a polymeric, or plastic, material. The metallic post is comprised substantially of aluminum or other suitable metals or alloys. The upper and lower shell portions define a cavity and a section of the post between the first and second plates traverses through the cavity.
Abstract:
This invention relates to a double-plenum or double-chamber inlet manifold or splitter, made up of a structural unit comprising two distinct coupled plenums with a common wall, an inlet opening for each of the two plenums and several pipes through each of the said plenums, the said superimposed plenums having substantially flattened general structures and forming, with their respectively connected inlet openings and pipes, two independent circulation circuits running from the entrance at the inlet openings to the outlet at the external openings of the pipes, the said external or outlet openings of the pipes being grouped in pairs, with each pair having an opening of each of the two types of pipes; the manifold comprises two one-piece parts assembled together, in a gas-tight manner, at the continuous assembly areas, a first part incorporating at least the two inlet openings and first portions of the walls of the two plenums, contiguous to the said openings and the second part incorporating the pipes and second portions of the walls of the two plenums, contiguous to the said pipes and complementary to the above-mentioned first portions.
Abstract:
A method and apparatus for welding two or more subcomponents together is described. The subcomponents may be welded to one another along seams, whereby sections of the seam that comprise similar materials are heated to a degree suitable for joining together those particular portions of the seam. Other sections of the seam may be heated to a different degree depending upon the material characteristics employed in that section of the seam. Embodiments of the apparatus include features for holding the subcomponents, simultaneously heating seams of each component, positioning the mating subcomponents together, and applying pressure between mating subcomponents to join them together.
Abstract:
An intake passage is formed by connecting an upper case 10 and a lower case 20 of an intake manifold. The lower case 10 has a recessed portion 50 on part of an inner surface 17a of a side wall 17. The recessed portion 50 has a deep surface 53 to which a negative pressure outlet port 42 opens, and an opening 51 opened upwards is provided in an upper portion of the recessed portion 50 in a position which opposes to the upper case 20 in a vertical direction A0. The upper case 20 has a projecting portion 60 which extends further downwards towards the negative pressure outlet port 42 than mating surfaces 10a, 20a and projects into the recessed portion 50 through an opening 52. The projecting portion 60 is positioned between the negative pressure outlet port 42 and the inner surface 17a in a horizontal direction A1.
Abstract:
A method for manufacturing a resonator is disclosed in which a sleeve insert is placed into a fixture within a blow molding apparatus. The sleeve insert has a wall with a first plurality of apertures in the wall at a first axial distance and a second plurality of apertures in the wall at a second axial distance. A parison is slid over the sleeve insert; the mold is clamped over the parison causing the parison to press into the sleeve insert at three locations: near the ends of the sleeve insert and at a location between the pluralities of apertures; and air is blown into the sleeve insert, via a blow pin, to expand the parison into the walls of the mold to form cavities proximate the first and second pluralities of aperatures. After cooling, the mold opens to release the newly formed resonator.
