Abstract
LA INVENCION SE REFIERE A UNA VALVULA DE MANDO PARA MEDIOS DE PRESION NEUMATICOS O HIDRAULICOS CON UNA CARCASA, QUE PRESENTA UN PRIMER Y UN SEGUNDO EMPALME PARA EL MEDIO DE PRESION, LOS CUALES ESTAN UNIDOS RESPECTIVAMENTE CON UNA ZONA DEL MEDIO CIRCULANTE Y CON UN ORGANO DE LA VALVULA DISPUESTA EN LA CARCASA, QUE ACTUA CONJUNTAMENTE CON EL ASIENTO DE LA VALVULA. EL ORGANO DE LA VALVULA ES ADEMAS CONTROLADO DE FORMA DESPLAZABLE, CONSIDERANDO LA MISMA VARIACION DEL VOLUMEN EN LA ZONA DEL MEDIO CIRCULANTE, PARA CONTROLAR LA VARIACION DE LA SECCION DEL MEDIO CIRCULANTE LIBRE DE LA VALVULA, DE TAL MANERA QUE, SE PRODUCE AL ABRIR LA VALVULA UN AUMENTO DEL VOLUMEN DE LA ZONA DEL MEDIO CIRCULANTE, Y AL CERRAR LA VALVULA UNA DISMINUCION DEL VOLUMEN.
