Abstract
A control valve for a heat management module of a motor vehicle is provided, which includes a valve disk, a valve shaft connected to the valve disk, and a shaft bearing on which the valve shaft is mounted such that it can move axially from a bearing surface. The control valve further includes a radial spring biased radially towards the shaft bearing. A receiving groove of the valve shaft includes an inhibiting section and a free-running section that are axially separated by a clamping wedge, The radial spring, in the region of the bearing surface is unable to overcome the clamping wedge and the radial spring is pressable radially by the clamping wedge such that the valve shaft is inhibited in the axial direction away from the free-running section. A control position can be held in a continuous manner without energy in a small installation space.
