Abstract
SE PRESENTA UN DISPOSITIVO OBTURADOR DEL VASTAGO DE UNA VALVULA ADAPTADO PARA QUE UN VASTAGO DE VALVULA QUE SE MUEVE EN SENTIDOS ALTERNATIVOS (18) DISPUESTO EN EL INTERIOR DE UNA GUIA DE VALVULA (16) PUEDA TOLERAR VARIACIONES MAYORES EN LA ALTURA DE LA GUIA. EL DISPOSITIVO INCLUYE UNA CUBIERTA CILINDRICA HUECA INFERIOR (14) Y UNA CUBIERTA CILINDRICA HUECA SUPERIOR (12), AMBAS DISPUESTAS ALREDEDOR DE LA GUIA DE LA VALVULA. LA CUBIERTA CILINDRICA HUECA SUPERIOR ES CAPAZ DE SER TELESCOPICAMENTE RECIBIDA DENTRO DE LA CUBIERTA CILINDRICA HUECA INFERIOR. UN MIEMBRO OBTURADOR (20) SE FIJA A LA CUBIERTA CILINDRICA HUECA SUPERIOR, EL MIEMBRO OBTURADOR SE EXTIENDE RADIALMENTE HACIA EL INTERIOR DE FORMA QUE SE ENCAJE ALREDEDOR DEL VASTAGO DE LA VALVULA (18) Y SE EXTIENDE AXIALMENTE HACIA ABAJO DE FORMA QUE SE ENCAJE EN LA GUIA DE VALVULA (16).
