Abstract

LA INVENCION SE REFIERE A UN EQUIPO DE CENTRADO PARA VALVULAS DE DIRECCION, DISPONIENDO EL EQUIPO DE UNA BARRA (1) DE TORSION MONTADA ENTRE UN ELEMENTO (2) DE ENTRADA DE ACCIONAMIENTO Y UN ELEMENTO (3) DE SALIDA DE ACCIONAMIENTO. DADO QUE LA BARRA (1) DE TORSION NO TIENE UNA POSICION DE CENTRADO EXACTA, UN ENCASQUILLADO (3A) DE VALVULA CONECTADO AL ELEMENTO (3) DE SALIDA DE ACCIONAMIENTO DISPONE DE UNA PERFORACION (6) RADIAL EN LA QUE SE AJUSTA UN PASADOR (7) CON UN EXTREMO DE CORONA QUE ENGRANA EN UNA RANURA (8) DE SUPERFICIE DE BISEL. EL PASADOR (7) ES ACTUADO POR MEDIO DE UN RESORTE (11) DE FORMA ANULAR, RANURADO. EL RESORTE (11) ESTA AJUSTADO EN UNA RANURA (10) ANULAR Y DISPONE DE UNA SECCION (12) APLANADA. EN LA VECINDAD DE LA SECCION (12) APLANADA, EL PASADOR (7) BLOQUEA DENTRO DE UN VACIADO (13) EN EL RESORTE (11). EL DISPOSITIVO DE CENTRADO PROPUESTO PERMITE QUE LOS COMPONENTES ROTATIVOS MUTUAMENTE SEAN POSICIONADO DE FORMA EXACTA EN LA POSICION NEUTRA.
