DROSSELKLAPPENVORRICHTUNG FÜR EINE VERBRENNUNGSKRAFTMASCHINE

摘要

A throttle plate pivots about a pivot axis through a positioning device to close or open a bore (2) relative to a seat face (8) formed by the inner wall (9) of the housing (1). The pivot axis is offset with respect to the plate so that one throttle blade (5) pivots away from the cross-section of the bore and the other blade pivots towards the cross-section of the bore when the bore is opened. A radial peripheral surface (7) of the plate is formed as a sphere in section so that the peripheral surface of the plate abuts the seat face with linear contact in the position closing the bore.
