Abstract
A invention relates to a throttle body which has at least one housing (14) and an actuator (18), which is arranged in the housing (14) and drives a moving element (6). The outlay on the production and assembly of the throttle body is particularly low while, at the same time, particularly severe heating of the actuator (18) is reliably avoided during operation of the actuator (18) wherein, the housing (14) is manufactured from plastic (K), and functional elements of the actuator (18) are arranged in the housing (14) and are at least partially surrounded by plastic (K). The moving element (6) is surrounded by a stub pipe (4), a functional element of the actuator (18) and the stub pipe (4) being connected to one another in a heat-conducting manner.
