噛合う螺旋状の凹溝を有する雄ロータとが、断面
まゆ形の内周面を有するハウジング内に夫々回転
可能に収納され、かつこのハウジングの両端部に
高圧側流入口と低圧側吐出口とが設けられてなる
スクリユー式膨張機において、上記雌雄ロータと
ハウジング内周面との間に画成される膨張室の適
宜位置から上記吐出口に至る１つあるいは複数の
バイパス通路を形成するとともに、このバイパス
通路に、上記膨張室の内部圧力が吐出口圧力より

を特徴とするスクリユー式膨張機。 A male rotor having a spiral protrusion and a male rotor having a spiral groove that engages with the protrusion are each rotatably housed in a housing having an inner peripheral surface with a cocoon-shaped cross section. In a screw type expander in which a high-pressure side inlet and a low-pressure side outlet are provided at both ends of the housing, the above-mentioned discharge is inserted from an appropriate position in an expansion chamber defined between the male and female rotors and the inner peripheral surface of the housing. One or more bypass passages leading to the outlet are formed, and the bypass passage is provided with a check valve that opens when the internal pressure of the expansion chamber is lower than the discharge port pressure. Screw type expansion machine.
