Regulator with hysteresis-affected characteristic curve

A regulator having a hysteresis-affected characteristic curve includes a manually operable actuating element for presetting a desired control variable, an axially displaceable control slide for adjusting the preset control variable in accordance with said control slide's axial displacement and, a control incline, having a control face, coupled to said actuating element for converting the actuating elements' adjustment movement into an axial displacement of the control slide, said control face rises in the adjustment direction of said actuating element, said control slide via a spring force rests in the axial direction,

• wherein a toothing bears along the control face of said control incline, said toothing includes a multiplicity of equidistantly arranged teeth which have, in each case in two mutually perpendicular planes extending in the displacement direction of the control incline, a sawtooth-like contour in each case with one rising edge for running up the control slide and a falling edge which follows in the displacement direction, the rising edge of the one tooth contour falling away in the one displacement direction of the control incline and the rising edge of the other tooth contour falling away in the other displacement direction inversely to the latter rising edge of the control incline, said falling direction of the rising edge of the tooth contour, in the plane perpendicular to the control face of the control incline, coincides with the falling direction of the control face.
