The invention relates to an induction port with an optimal noise level, especially a suction pipe for use as an induction port of an internal combustion engine.

The invention relates to an air induction device (11), comprising a housing (12) with an open induction pipe (13) leading away from it and an supplementary induction pipe (14).

Disclosed is an intake device comprising a collector (1) and at least one intake pipe (2) to which a first and a second intake pipe segment (3, 4) are assigned.

A hose section (10) for a sea water suction hose (50) and a method of assembling a sea water suction hose (50) is provided.

The invention relates to a suction nozzle for a vacuum cleaner, that can be connected to a suction pipe and/or a suction tube of the vacuum cleaner.

Through said bellows (2) is passed a suction-air pipe (3).

An air suction pipe is provided on the top of the housing.

In addition the suction header (7) is connected to an air-suction pipe (4), which is in turn connected to an aspirator.

The air suction seat (2) is connected with an air suction power device (4) through a suction pipe (3).

A fitting (10) secures a vacuum hose (20) to a wand or tank of a vacuum cleaner.

Thus, sucking force occurs on a suction hose (3) through a suction passage (60) and the excrement tank (13).

The vacuum cleaner comprises a suction nozzle (9) which can be coupled to the housing via a suction tube (13) and a suction hose (15).

A suction pipe (2) with a suction opening (6) for sucking in the thread (7) is fitted to the extraction channel.

There is a rear sucking pipe located on the wall of a certain spout.

The invention relates to a suction pipe (10) which has shells (11a, b).
