Component of the pneumatic or hydraulic circuit, provided with an arrangement of a section of the drawings, in service pressures relatively castings

摘要

In a component of the pneumatic or hydraulic circuit, of the type comprising a rod thread and an annular rim forming a plane of etching, projecting radially, an annular seat 14, 15 is shaped in accordance with the connection zone between said rod 11 and the flange 12. The seat 14, 15 comprises a substantially triangular section with a dimension which constitutes an extension of the profile of the rod and the other dimension inclined present an angle between 30 and 60, and a depth such that it can contain the o-ring is the state not deformed in order that - latter projects from said plane of etching over a height which is greater at the half of the diameter of its cross section.
