Abstract

EL DISPOSITIVO REIVINDICADO PROPORCIONA UN MACHO (11, 12) CONSTITUIDO POR DOS ELEMENTOS COAXIALES QUE DEFINEN LA SUPERFICIE INTERIOR DE UN CUERPO ANULAR DOTADA DE PARTES SOCAVADAS O MUESCAS INTERNAS, QUE COMPRENDE, DE PREFERENCIA, UNA ROSCA. LAS DOS BASES DEL CUERPO ANULAR A FORMAR ESTAN DEFINIDAS POR UNA PLACA DE DESMOLDEO (30) Y UN MANGUITO ALIMENTADOR GIRATORIO (20). LA SUPERFICIE EXTERIOR LATERAL DEL CUERPO QUE HA DE FORMARSE ESTA DEFINIDA, POR OTRA PARTE, POR UNA ENVUELTA AXIALMENTE DESLIZANTE (13).
