A butterfly body provided with a valve body having a through duct, a butterfly valve moving on command within the through duct in order to regulate the flow of fluid through this through duct and a device for moving the butterfly valve mechanically coupled to this butterfly valve in order to be able to vary, on command, the position of the latter within the duct, so as to control the flow of air flowing through the through duct, the valve body being made entirely from plastic and having, embedded within it, a bushing of metal, within which the electrical actuator controlling the displacements of the butterfly valve is adapted to be housed.

Butterfly body

Throttle body in which on the internal wall of the feed pipe there is provided at least one channel the base of which defines together with external edge of the butterfly valve at least one limp-home flow and in which on the internal wall of the feed pipe there is provided a curvilinear section, adjacent to the channel, the base of which defines together with the external edge of the butterfly valve at least one idling flow.
