Control valve for a heat management module

A control valve for a heat management module of a motor vehicle, the control valve comprising:

• a valve disk configured to rest on a valve seat in a closed position,
• a valve shaft connected to the valve disk, the valve shaft configured to move along a predetermined travel path defined by a first end stop and a second end stop, and the valve shaft having a receiving groove, the receiving groove including:
• an inhibiting section,
• a free-running section, and
• a clamping wedge configured to axially separate the inhibiting section and the free-running section, and
• a shaft bearing configured to support the valve shaft such that the receiving groove can move axially within the shaft bearing, the shaft bearing having at least one reversing groove,
• a radial spring disposed within the receiving groove of the valve shaft, the radial spring biased radially towards the shaft bearing,
• wherein:
• i) when the radial spring is moved in a first axial direction to a region of the shaft bearing between the first and second end stops, movement of the valve shaft in a second axial direction is inhibited by the clamping wedge, and ii) when the radial spring is received in a first one of the at least one reversing groove, the clamping wedge can be overcome by the radial spring so that the valve shaft can move in the second axial direction.
