To provide a pipe joint for a refrigerant flow path capable of withstanding use in a supercritical state and excellent in workability.SOLUTION: A pipe joint for refrigerant flow path comprises: a pipe joint body having a connection part having an engagement part that engages with the outer peripheral surface of the pipe; a shaft that can move inside the pipe joint body in a central axis direction of the pipe joint body; and a cam arm that is connected to the shaft via an axis perpendicular to the central axis, and moves a predetermined angle in a rotation direction with the vertical axis as a center. When the end part of the cam arm comes into contact with the end part of the pipe joint body, the shaft moves along the central axis in the direction of the connection part, and engages with the end part of the pipe.SELECTED DRAWING: Figure 4
【課題】超臨界状態での使用に耐え、作業性に優れた冷媒流路用の配管継手を提供することを目的とする。【解決手段】冷媒流路用配管継手であって、前記パイプの外周面と係合する係合部を有する接続部を有する配管継手本体と、前記配管継手本体の内部を、前記配管継手本体の中心軸方向に移動可能なシャフトと、前記シャフトと前記中心軸に垂直な軸を介して接続され、当該垂直な軸中心とした回転方向に所定角度移動するカムアームと、を備え、前記カムアームの端部が、前記配管継手本体の端部と接触することで、前記シャフトが、前記中心軸に沿って前記接続部の方向に移動し、前記パイプの端部と係合することを特徴とする。【選択図】図4
