摘要： A multi-channel rotary joint comprising-elastic seal rings each having an annular groove that are used to form a low-pressure channel space and a high-pressure channel space between the opposing peripheral surfaces of a joint housing and a rotator that rotates inside the joint housing. Seal rings that seal the low-pressure channel space which forms part of a vacuum suction route are engaged with and supported by one of the opposing peripheral surfaces such that annular grooves are disposed symmetrically and opening into spaces adjacent to the low-pressure channel space. The seal rings that seal the high-pressure channel space which forms part of a pressurized fluid supply route are engaged with and supported by one of the opposing peripheral surfaces such that the annular grooves are disposed symmetrically and opening into this high-pressure channel space.

摘要： A quartz pipe joint of the present invention can be used in a connection of, for example, a quartz pipe and a quartz pipe, or a quartz pipe 7 and a synthetic resin tube. The quartz pipe joint A has a joint body having a tapered pressing face a cylindrical sealing member 33 having a tapered receiving face 33, a lock ring which can deform to increase its diameter and deform to reduce its diameter and which can be fitted into an annular groove of the quartz pipe and a nut. When the lock ring fitted into the annular groove and the sealing member fitted into the quartz pipe are clamped by threadedly connecting the nut to the joint body, the sealing member is deformed to reduce its diameter by the function of the pressing face and the receiving face, so as to closely contact with the outer peripheral face of the quartz pipe, thereby exerting sealing properties. The lock ring engages with a groove wall of the annular groove to prevent the quartz pipe from slipping off from the joint.
摘要翻译：本发明的石英管接头可以用于例如石英管和石英管，石英管7和合成树脂管的连接。石英管接头A具有锥形按压面的接头体，具有锥形接收面33的圆筒形密封构件33，能够变形以增大其直径并变形以减小其直径的锁定环，并且可以将其嵌入环形石英管槽和螺母。当通过螺母将螺母连接到接头体上而将装配到环形槽中的锁定环和装配到石英管中的密封构件夹紧时，密封构件通过按压面和接收面的功能而变形以减小其直径，以便与石英管的外周面紧密接触，从而施加密封性。锁定环与环形槽的槽壁接合，以防止石英管从接头滑落。

摘要： A press insertion rod is passed through and supported by a press insertion rod supporting portion of a jig body in an advanceable and retractable manner. An inner ring which is to be pressingly inserted into one end portion of a pipe member made of resin is held by a ring holder. The ring holder is coupled idly rotatably and detachably to a tip end portion of the press insertion rod via a holder block.

摘要： A sealing member is provided at an inner periphery sealing portion thereof with an inner tube portion arranged to be moved toward a fuel feed port inner side with the insertion of a fuel feed nozzle and to be moved toward a fuel feed port opening side with the removal of the fuel feed nozzle. The inner tube portion is provided, at the outer periphery of the end thereof at the fuel feed port opening side, with a tapered tube portion extending toward an outer tube portion side. With the movement of the inner tube portion toward the fuel feed port opening side, the inner tube portion is increased in inner diameter such that the increased inner diameter is greater than the outer diameter of the fuel feed nozzle, and with the movement of the inner tube portion toward the fuel feed port inner side, the inner tube portion is reduced in inner diameter, causing the same to stick fast to the outer periphery of the fuel feed nozzle.
摘要翻译：密封件在其内周密封部分处设置有内管部，该内管部布置成随着燃料供给喷嘴的插入而朝向燃料供给口内侧移动，并且朝向燃料供给口开口侧移动，的燃料供给喷嘴。内管部在其燃料供给口开口侧的端部的外周设有向外管部侧延伸的锥形管部。随着内管部分朝向燃料供给口开口侧的运动，内管部分的内径增加，使得内径增大，大于燃料供给喷嘴的外径，并且随着内管部分的运动管部朝向燃料供给口内侧，内管部内径减小，使其相对于燃料供给喷嘴的外周快速地粘贴。
