Description
上記課題を解決するために、例えば特許請求の範囲に記載の構成を適用する。即ち、ローブを有し少なくとも1つずつの雄スクリューロータ及び雌スクリューロータと、前記雄スクリューロータ及び前記雌スクリューロータを格納して圧縮作動空間及び吸込作動空間を構成するケーシングとを備え、圧縮作動空間に供給された液体と吸込み気体を圧縮し、前記雄スクリューロータ及び前記雌スクリューロータの吐出側端面に対向する吐出ポートから圧縮混合気体を吐き出すスクリュー圧縮機本体であって、前記雌スクリューロータが、軸方向に深さを有する凹部を前記吐出側端面に備え、前記凹部は、前記雌スクリューロータが吐出完了直後の位置のときに、前記雌スクリューロータの軸方向に対しては前記吐出ポートに連通すると共に、前記雌スクリューロータの周方向に対しては前記雌スクリューロータの回転方向の吸込作動空間には連通せずに反回転方向の圧縮作動空間にのみ連通するものであるスクリュー圧縮機本体である。 In order to solve the above problems, for example, the configuration described in the claims is applied. That is, a casing constituting the male clew rotor and a female screw rotor by at least one has a lobe, the male clew rotor and the compressed working space to store the female screw rotors and the suction working space, compressing the gas suction and supplied to the compressed working space liquid, a said male clew rotor and screw compressor body for discharging the compressed gas mixture from the outlet port facing the discharge side end surface of the female screw rotor, wherein female screw rotor is provided with a recess having a depth in the axial direction to the discharge-side end face, the recess, when the female screw rotor position after discharge completion straight, with respect to the axial direction of the female screw rotor Does not communicate with the suction operating space in the rotational direction of the female screw rotor , but communicates only with the compression operating space in the counter-rotating direction with respect to the circumferential direction of the female screw rotor. A screw compressor body.
