THROTTLE VALVE NOZZLE FOR AN INTERNAL COMBUSTION ENGINE

摘要

The invention relates to a throttle valve nozzle (1) for an internal combustion engine, comprising a channel (3) through which a flow is possible and a throttle valve (2), which is arranged in the channel (3) and which can be rotated in a first rotational direction (201) into a first blocking position (101) that closes the channel (3). An inner wall (4) of the channel (3) is equipped with a first curved contour (41) against which the throttle valve (2) rests in the first blocking position (101), and the inner wall (4) is equipped with a second curved contour (42), against which the throttle valve (2) also rests in the first blocking position (101). The throttle valve (2) can be rotated in a second rotational direction (202) opposite the first rotational direction (201) into a second blocking position (102) which closes the channel (3).
