セルフシールカツプリング。[Claims for Utility Model Registration] 1. An inlet side passage 2 and an outlet side passage 3 are provided independently of each other in the coupling body 1, and the inlet side passage 2
Main side self-sealing valves 6, 6 are provided at the outlet side portion 4 of the outlet side portion 4 and the inlet side portion 5 of the outlet side passage 3, respectively. Each self-sealing valve port 14 is pushed out in the direction
The self-sealing valve port 14 is configured to be closed and pushed back inward by an external force to open the self-sealing valve port 14, and the inlet side passage 2 and the outlet side passage 3 are connected to a short-circuit passage 10.
In a self-seal coupling with a short-circuit passage for a hydraulic circuit, the short-circuit passage 10 is configured to be openable and closable by a short-circuit valve 11. The cylindrical valve body 12 is configured to slide reciprocatingly inside one of the passages 2, 3 and open/close the communication port 15 between the one passage 2, 3 and the short-circuit passage 10. The self-sealing valve is configured to move together with one self-sealing valve body 7, and one self-sealing valve body 7 is pushed outward by one valve-closing pressing means 8 to close one self-sealing valve port 14. In this case, when the cylindrical valve body 12 is in the short-circuit valve open state in which the communication port 15 is opened, and one of the self-sealing valve bodies 7 is pushed back inward by an external force and the self-sealing valve opening 14 is opened, the cylinder is in the short-circuit valve open state. The type valve body 12 is configured to be in a short-circuit valve closed state in which the communication port 15 is closed, and the valve opening/closing stroke of one self-sealing valve body 7 and the cylindrical valve body 12 is made shorter than the valve opening/closing stroke of the other self-sealing valve body 7. A self-sealing coupling with a short-circuit passage for hydraulic circuits, which is characterized by a large setting. 2. According to claim 1, the opening surfaces 72 and 73 on the connection end side of each of the passages 2 and 3 on the inlet side and the outlet side are located close to the self-sealing valve ports 14 of each main self-sealing valve 6, respectively. Self-sealing coupling with shorting passage for the hydraulic circuit as described.
