Screw compressor



                        1. When the rotor is unmesh at the intake end of the
                            cylinder, air is drawn into the cavity between the
                            main rotor blades and the secondary rotor grooves.









                                                                    2. As the rotation continues, the tip of the rotor passes through
                                                                        the edge of the air inlet, trapping air in the cell formed by the
                                                                        rotor cavity and the cylinder wall.
