    • A throttle body (10) with a housing (12) comprising a housing cover (17) and a housing body (14) and with a through throttle aperture (20) for a throttle butterfly (26) arranged on a throttle-butterfly shaft (22), the throttle-butterfly shaft (22) being drivable as a function of specifiable parameters by an electronic system (56) arranged in the housing (12) by an electric actuator (32) likewise arranged in the housing (12) and having an actuator shaft (28), the position of the throttle-butterfly shaft (22) being detectable by a position detection device (70) arranged in the housing (12), is to have a particularly small space requirement and, at the same time, a contactless position detection device (70) for the throttle-butterfly shaft (22) For this purpose, the electronic system (56) for the electric actuator (32) is arranged in the housing cover (17), and the position detection device (70) comprises a Hall-effect magnet (76) arranged on the actuator shaft (28) and a Hall-effect sensor (72) arranged directly next to the Hall-effect magnet (76) for detecting the position of the throttle-butterfly shaft (22).
    • 具有壳体(12)的节气门体(10)包括壳体盖(17)和壳体(14),并且具有用于节流蝶阀(26)的通过节流孔(20),其布置在节气门 - 蝶形轴( 节气门 - 蝶形轴(22)可通过由同样布置在壳体(12)中的电致动器(32)布置在壳体(12)中的电子系统(56)作为可指定参数的函数驱动,并且具有 致动器轴(28),节气门 - 蝶形轴(22)的位置可由布置在壳体(12)中的位置检测装置(70)检测,具有特别小的空间要求,并且同时 ,用于节气门 - 蝶形轴(22)的非接触位置检测装置(70)为此,用于电致动器(32)的电子系统(56)布置在壳体盖(17)中,并且位置检测装置 (70)包括布置在致动器轴(28)上的霍尔效应磁体(76)和霍尔效应传感器(Hall-effect sens) 或(72)直接布置在霍尔效应磁体(76)旁边,用于检测节气门 - 蝶形轴(22)的位置。
