ABSTRACT:
The invention relates to a throttle plate port whose pivot axis is disposed so as to be axially offset with respect to the throttle plate and whose radial peripheral surface is shaped, at least by sections, in the form of spherical sectors, where in the position which closes the bore the peripheral surface of the throttle plate abuts, in the form of a line, the seat face of the housing. Through this type of eccentric disposition and simultaneous realization of the peripheral surface, the housing can be realized without undercuts and nonetheless precise dosing can be achieved in the case of small pivot angles.
