Claims

[Scope of Claim for Utility Model Registration] A device for bridging the flow of ultra-high pressure liquid such as oil or water from a stationary side member to a rotating side member, or from a rotating side member to a stationary side member, and which includes the front part of a stationary body. A rotary body is rotatably fitted on the outside, and a plunger that is slidable in the direction of the rotational center axis of the rotary body is inserted into the rotary body, and a pressure-welding spring is attached with the rear end face abutting against the front end face of the stationary body. The plunger is formed into a two-stage plunger with a small diameter portion at the front and a large diameter portion at the lug, and is communicated with the front portion of the large diameter sliding hole of the plunger. A rotary A port is formed in the rotary body, and a rotary B board is formed by communicating between the front part of the large-diameter sliding hole and the step surface of the plunger in the rotary body, while the rear end of the stationary body a stationary A port is formed in the stationary main body, a stationary B port is formed in the stationary ring externally fitted to the rear of the stationary main body, and a stationary main passage communicating the stationary A port and the front end surface of the stationary main body; A stationary sub-passage is formed in the stationary body, which communicates the stationary B port with the front end surface of the stationary body, and a rotation main passage and the rotation B passage, which communicates the rotation A port with the rear end surface of the plunger. A rotary sub-passage communicating between the port and the rear end of the plunger via the stepped surface is formed in the plunger so as to face the stationary sub-passage, and the area of the press-contact rear end of the flansha and that of the plunger are The area difference between the front end surface area and the step surface area is balanced in accordance with the working pressure and rotational speed of the liquid. A rotary joint for ultra-high pressure liquid, characterized in that it is constructed so that pressure contact force is applied between the front end surface of a stationary body and the rear end surface of a plunger.
