ABSTRACT:
A regulator with a hysteresis-affected characteristic curve has a manually operable actuating element for presetting a desired control variable, an axially displaceable control slide for adjusting the preset control variable and a control incline which is coupled to the actuating element. The control incline converts, by means of a rising control face, the adjustment movement of the actuating element into a axial displacement of the control slide. For the purpose of compensating the hysteresis when adjusting a control a variable such that the same control variable is brought about by rotating the actuating element to the left or to the right into the same setting, the control incline bears a toothing along its control face. Each tooth has, in two planes which extend along the displacement direction of the control face and are perpendicular to one another, a sawtooth-like contour with in each case a rising edge for running up the control slide and a falling edge which follows in the displacement direction. Each tooth contour is associated with one of the two displacement directions. Each tooth contour is associated with one of the two displacement direction of the control incline and deflects the control slide in the axial direction or transversely thereto.
