Abstract (en)
[origin: DE4227951A1] In a rotating actuator, especially with the use of plastic intake pipes and connections, noise is produced as a result of turbulence which should be prevented. To this end there are plane boundary surfaces (25) at the throttle aperture (13) and another (26) at the outlet aperture (14). In addition, there are in the intake stub flow-assisting transitions with a convex and a concave region (40, 41) of a truncated conical taper (24) towards the boundary surfaces (25) and in the outlet stub (6) there is a flow-assisting transition with a convex and concave region (42, 43) towards the truncated conical broadening (27) of the outlet stub (6). The rotating actuator is especially usefull to control the idling speed of internal combustion engines.
