Abstract

LA INVENCION SE REFIERE A UN PISTON CON UNA VALVULA CENTRAL, EN PARTICULAR PARA AMPLIFICADORES HIDRAULICOS. SON CONOCIDOS LOS PISTONES QUE DISPONEN DE UNA INSERCION (6) DE VALVULA QUE CONSISTE EN UNA INSERCION (8) DE COJINETE RODEADA RADIALMENTE POR UN ASIENTO (7) DE VALVULA. LA DESVENTAJA DE TALES INSERCIONES DE VALVULA ES QUE NO ES SUFICIENTE LA CONEXION DE FUERZA ENTRE AMBOS ELEMENTOS EN LA DIRECCION AXIAL EN ALGUNOS CASOS. PARA AYUDAR A RESOLVER ESTE PROBLEMA, LA INVENCION TIENE PREVISTO UN CORTE INFERIOR, DE MODO QUE EL ASIENTO (7) DE VALVULA INTERACCIONA LA INSERCION (8) DE COJINETE A PARTIR DE LA PARTE POSTERIOR EN AMBAS DIRECCIONES. EN UN DESARROLLO VENTAJOSO DE LA INVENCION, LA INSERCION (6) DE VALVULA ESTA DISPUESTA DE FORMA SIMETRICA Y SE DISPONE DE UNA PROYECCION DE SELLADO PERFILADO SOBRE EL ASIENTO DE VALVULA. LA GUIA DEL EMPUJADOR (19) DE VALVULA ESTA PROVISTA EN EL MISMO PISTON (1).
