    • A suction pipe unit (10) for a multi-cylinder internal combustion engine has a pipe-shaped intake distributor (12) at least long suction pipes (13) extending from said distributor and leading to the individual cylinders. Short suction pipes (14) also extend from the distributor (12) and lead into the corresponding long suction pipe (13). The intake distributor (12) and the long and short suction pipes (13, 14) are made from a single-component housing (11), one of which has an opening (21) which cuts through the short suction pipe (14). A switch (15) is housed in said opening (21). Said switch has butterfly valves (16), a valve holder (17), an axle (19) and a switch holder (18). Rotation of the axle (19) opens or closes of the short suction pipe (14). The switch (15), in contrast to the prior art, does not have seals which can jam during assembly. A space saving solution is provided by placement of the butterfly valves (16) on the universal axis (19).
    • 用于多缸内燃机的进气歧管(10)具有管状进气歧管(12),至少长吸管(13)从该管状进气歧管(12)通向各个气缸。 短吸管(14)也从进气歧管(12)流出并通向相关的长吸管(13)。 进气歧管(12)和长吸入管和短吸入管(13,14)由具有与短吸入管(14)相交的开口(21)的整体式壳体(11)形成。 在该开口(21)中,引入具有翼片(16),翼片框架(17),轴线(19)和开关元件框架(18)的开关元件(15)。 通过转动轴(19),可以打开或关闭短吸管(14)。 与已知的解决方案相比,开关元件(15)与已知的解决方案形成对照的是,没有密封元件在组装期间可能被卡住,并且通过将翼片(16)布置在连续轴线(19)上提供节省空间的解决方案。
