A control valve for an oil-injected screw-type compressor, in particular for installation in a vehicle, wherein oil located in a screw-type compressor housing can be supplied in a controlled manner via the control valve to a heat exchanger and/or to a bypass in such a way that cold oil is conducted through a bypass around the heat exchanger and warm oil is conducted through the heat exchanger. A control valve is provided for an oil-injected screw-type compressor and ensures rapid heating of the oil in the screw-type compressor even with a short activation time. The control valve has a control piston that is actuated by a control element and cooperates respectively with a heat exchanger opening disposed in a control valve housing and a bypass opening, and that the control piston controls at least one bypass opening which cooperates with the heat exchanger opening.
