The rotation is controlled by a precision gear (D<\/span>) synchronized. A screw rotor has a left-hand thread, another has a right-hand thread. compression chambers (E<\/span>) are formed with the compressor housing by the special shape of the screw rotors. Due to the opposite rotation of the two screws, the one with the suction connection (G<\/span>) connected chamber increases and transports the gas into the compression chamber. The arrow indicates the axial displacement of the chambers in the housing. On the pressure side, the chamber is pushed against the axial housing wall and the volume is reduced until the face of the screw opens the pressure channel and the pre-compressed gas flows through the pressure port (f<\/span>) is discharged.
