ROTARY JOINT FOR CONNECTING HYDRAULIC PIPES AND HYDRAULIC PIPING WITH ROTARY JOINTS

摘要

The present invention pertains to a rotary joint (1) for connecting hydraulic pipes (2), comprising a first annular socket flange (5) having a partly spheroid first concave bearing surface (5a); and a first annular ball flange (6) having a partly spheroid first convex bearing surface (6a); wherein the curvature of the first concave bearing surface (5a) of the first annular socket flange (5) corresponds to the curvature of the first convex bearing surface (6a) of the first annular ball flange (6).
