An air flow conduit system is presented for air flow communication between an air filter mechanism and an engine intake manifold. The conduit system comprises substantially rigid straight conduit members joined in fluid communication by connector systems having elbow-shaped conduit members. A narrow end of a conduit member is received within a broad end of a next adjacent conduit member. Sealing engagement occurs via an elastomeric seal member having ribs thereon positioned radially between the inner and outer conduits. A preferred rib arrangement is provided, to insure a flexible, multi-point, seal system. |

DETAILED DESCRIPTION The present invention concerns a conduit system providing for air flow communication between an air filter arrangement or the like and an intake manifold in an engine assembly.
Generally, the arrangement is useable in almost any internal combustion engine arrangement, including mobile vehicles such as trucks, construction equipment and agricultural equipment.
Also, the system may be used in stationary engine arrangements such as power generators and compressors.
According to the invention, an adjustable system useable for a variety of arrangements, is provided by means of relatively rigid, interconnected, conduit elements.
In general, the system involves a first conduit member, a central conduit arrangement, and an end conduit member, attached in series to extend between the filter and the air intake manifold.
The central conduit arrangement may comprise a single, unitary, member or a plurality of members attached in series.
In one embodiment shown, the arrangement includes only three conduit elements.
That is, the central conduit arrangement comprises a single member.
A reason for the near universal nature is that a three-component system involves four critical joints: a first critical joint between a first conduit member and an air filter arrangement to which the first conduit member is attached; a second critical joint between the first conduit member and the second conduit member; a third critical joint between the second conduit member and the third conduit member; and a fourth critical joint between the third conduit member and the air intake manifold.
For the preferred embodiment, advantages are derived from the fact that fewer critical joints are involved than for many conventional arrangements, hence the system is less likely to fail.
Further, each critical joint is rotationally adjustable.
As a result of both rotational and longitudinal adjustability, an overall nearly universal arrangement is provided.
Critical joints between conduit sections are of a preferred, advantageous construction
