Claims

[Scope of Claim for Utility Model Registration] An ultra-high pressure pressurizing device comprising a body and a plunger that reciprocates within a pressurizing chamber in the body by external power to generate an ultra-high pressure in a processing fluid, wherein the body and the plunger a cylindrical pressure transmission chamber concentric with the axial center of the plunger provided on the body side between them; a processing fluid pressure chamber filled with the processing fluid flowing from the pressurizing chamber; and a processing fluid pressure chamber filled with sealing fluid. a movable sealing body concentric with the axial center of the plunger that partitions the pressure transmission chamber into a sealing fluid pressure chamber without leakage and is capable of freely reciprocating in the axial direction of the plunger; The sealing fluid pressure chamber is formed facing the movable sealing body via a fluid, and a concave small space is formed on the sealing fluid pressure chamber side between the outer periphery of the pressure transmission chamber, and the concave small space is An ultra-high pressure seal packing comprising: a fixed sealing body with a ring-shaped elastic body having a substantially rectangular cross section inserted into the body;
