Abstract
The disclosure relates to a control valve for a medium circuit of an internal combustion engine, in particular to a thermostat of a coolant circuit of the internal combustion engine. The control valve includes a valve housing, an expansible material element arranged in a valve body, an energy accumulator having an abutment element, a valve seat, and at least one locking element arranged on the abutment element, each locking element having a counter-latching face. The control valve has a first position wherein the counter-latching face of each locking element is in a non-positive connection with a corresponding latching face of the valve housing in order to force the control valve into a mechanically blocked, forced-open position, the latching face being formed by means of an opening edge in the valve housing. This position may enable a quick and reliable initial filling or refilling of the coolant circuit.
