Screw compressor with control slider and detector

A screw compressor, including a compressor housing having a screw rotor chamber arranged therein, two screw rotors that are arranged in the screw rotor chamber and are mounted on the compressor housing, each rotatably about a respective screw rotor axis, and engage in each other by means of their helical contours and each cooperate with compression wall surfaces which are adjacent thereto and partly surround them in order to receive gaseous medium that is supplied by way of a low-pressure chamber arranged in the compressor housing and to discharge it in a region of a high-pressure chamber that is arranged in the compressor housing, wherein the gaseous medium is enclosed in compression chambers that are formed between the helical contours and compression wall surfaces that are adjacent to the latter with an intake volume at low pressure and is compressed to a final volume at high pressure, and including at least one control slider that is arranged in a slider channel of the compressor housing and is adjacent to both screw rotors by means of slider compression wall surfaces and is movable in a direction of displacement parallel to the screw rotor axes and take a form that affects at least one of the final volume and an initial volume, the screw compressor has two control sliders, wherein a first control slider takes a form that affects the final volume and a second control slider takes a form that affects the initial volume, wherein a position determining device is provided for the two control sliders that includes a first position indicator, coupled to the first control slider, and a second position indicator, coupled to the second control slider, wherein both position indicators cooperate with a common detector that extends parallel to the direction of displacement of the control sliders and along which the position indicators are movable when the control sliders are moved, and the common detector is coupled to an evaluation device to indicate the respective positions of the position indicators along the common detector.

• displacement thereof, the first control slider is arranged on a side of the second control slider facing the high-pressure chamber, and wherein the first control slider is guided in relation to the second control slider by a telescopic guide;
• and
• wherein the telescopic guide including a guide receptacle and a guide body, with the guide body held on one of the two control sliders and the guide receptacle formed in one of the two control sliders.
