PERFECCIONAMIENTOS EN LOS SISTEMAS DE ELEMENTOS MODULARES PARA CONEXIONES PIVOTANTES Y ESTANCAS, MEJORAS EN LOS BRAZOS ARTICULADOS Y PERFECCIONAMIENTOS EN LOS DISPOSITIVOS DE ALI-MENTACION DE UNA PERFORADORA DE PIQUERAS.

摘要

Multi-path rotatable fluid couplings are formed from modular elements so as to have one, two or three axes about which relative rotation of supply and discharge conduits may occur. These modular elements may be employed in an articulated delivery system for multiple fluids wherein, for example, six pivot axes are provided through a combination of two or more couplings with interconnecting rigid conduits.
