A device for the control of at least one throttle diameter in a control line, especially in a line carrying fuel for an internal combustion engine, is proposed. The device includes at least one circle segment-like control section in a control bore intersecting the control line, the section pivotable around an axle and opening to a larger or lesser degree the throttle diameter formed by the intersection. The control bore has a circularly arched sealing surface surrounding the throttle diameter extending eccentrically to the axle and with which the control section, also disposed eccentrically to the axle and disposed pivotably, works together in such a way, that the radial distance between the circumference of the control section and the sealing surface is nearly zero when the control section is in a closed position, and increases during a pivotal movement in the direction of opening the throttle diameter. The radii of sealing surface and control section are of the same size and proceed from a circular arc with a radius around the center line of the axle.
