セルフシール継手の減圧装置。[Claims for Utility Model Registration] (1) Communication of the hydraulic oil flow path and sealing after the flow path is interrupted by the operation of the seal members provided in the male and female parts, which are the self-sealing joint components. Among automatic self-sealing joints, this is a device installed on the self-sealing joint component on the side connected to the hydraulic power source, and has a hydraulic pressure release passage communicating with the hydraulic oil flow path of the self-sealing joint component. Consisting of a seat and a valve body that releases or closes the hydraulic pressure release passage to the atmosphere by opening and closing the valve seat, and discharges residual hydraulic oil in the self-seal joint components when the self-seal joint is connected. A pressure reducing device for a self-sealing joint, characterized in that residual pressure within the self-sealing joint component is eliminated by doing so. (2) The pressure reducing device for a self-seal joint according to claim 1, wherein an oil storage container is attached to the atmosphere release end of the hydraulic pressure release passage.
