An excentric pin for an electronic throttle control assembly, which is used to adjust the default position of at least one spring used to control the position of a valve plate, where the valve plate is located in an opening of a housing in the electronic control assembly. The excentric pin is used to adjust the default angle of the valve plate to have an angular tolerance of +/&#x2212;0.10&#xb0;. The excentric pin is slideably pressed into an aperture of the housing of the electronic throttle control assembly, and turned using some type of driver. The electronic throttle control assembly may be a one-spring design, or a two-spring design, where the two-spring design requires only one spring pin and the excentric pin. Also, the excenter pin may be used to adjust the position of the sector gear, e.g., function as the lower mechanical stop to provide a minimum opening angle for low leakage, and a minimum opening angle to avoid throttle plate corking into opening of the housing.

A throttle body assembly includes a housing defining a throttle bore with a throttle plate in the bore and mounted on a shaft. An electric motor has a pinion gear. A gear assembly includes an intermediate gear and a sector gear and transfers rotational drive from the electric motor to the throttle plate. Biasing structure biases the sector gear and thus the shaft to cause the throttle plate to close the throttle bore defining a closed position thereof. When the motor is energized, rotation of the pinion gear causes rotation of the gear assembly, against the bias on the sector gear, thereby causing rotation of the shaft to move the throttle plate from the closed position to an open position. A position sensor assembly determines a position of the plate.

An electronic device () has a screen () protecting against radiofrequency electromagnetic fields, wherein the screen is formed by an at least partially conductive cap (). In order to avoid the formation of a defined conductive connection between the cap () and a reference potential, conductive two-dimensional regions () of the cap () are arranged in electrically insulated fashion at a short distance parallel to at least one two-dimensional region () of a conductor () of a reference potential. The two-dimensional regions act as a capacitor and a capacitive coupling () to the reference potential is produced which eliminates or attenuates radiofrequency electromagnetic interference fields, which enter the electronic device or are emitted from it.

A butterfly valve device (), particularly an electrically actuated butterfly valve device () e.g. for use in an intake manifold of an internal combustion engine is designed in such a way that the effort required for assembling the intake manifold can be reduced while the requirements regarding dimensional tolerances and tightness can be met and the number of parts is minimized. This aim is achieved by the fact that at least one housing part () of the butterfly valve device () is embodied monolithically along with an intake pipe () that is disposed upstream or downstream of the butterfly valve device ().
