Abstract
An electric control valve for a coolant compressor comprises a valve housing, an electric actuating drive, a valve body displaceable by the electric actuating drive between a first position and a second position inside the valve housing, a position sensor determining a position of the valve body, a suction-pressure sensor, and a control system. The control system is adapted to control a coolant flow from a high-pressure region into a crankcase-chamber-pressure region of the coolant compressor by controlling the position of the valve body via the electric actuating drive based on the suction pressure received from the suction-pressure sensor. The control system moves the valve body to the first position to connect the high-pressure region and the crankcase-chamber-pressure region if the suction pressure is below a predetermined threshold.
