Abstract

LA INVENCION SE REFIERE A UN AMORTIGUADOR DE VIBRACIONES HIDRAULICO, EN PARTICULAR PARA AUTOMOVILES, CON UN CUERPO (1) DE EMBOLO, QUE MUESTRA DOS GRUPOS DE CANALES (2,3) DE LIQUIDO CIRCULANTES EN CONTRASENTIDO, UNA VALVULA (4) CORRESPONDIENTE A LA CARGA DE PRESION DEL AMORTIGUADOR DE OSCILACION, ACTUANDO CONJUNTAMENTE CON EL GRUPO DE CANALES (2) DE LIQUIDO Y UNA VALVULA (5) CORRESPONDIENTE A LA CARGA DE TRACCION DEL AMORTIGUADOR DE VIBRACIONES ACTUANDO CONJUNTAMENTE CON EL OTRO GRUPOS DE CANALES (3) DE LIQUIDO. DE ACUERDO CON LA INVENCION EL EMBOLO MUESTRA AL MENOS UNA VALVULA (6) DE SOBREPRESION, QUE EN PRESIONES DE LIQUIDO ALTAS LIBERA AL MENOS UN BY-PASS ADICIONAL QUE EN LA DIRECCION DE CARGA RESPECTIVA NO ESTA CONEXIONADO CON LOS CANALES (2,3) DE LIQUIDO CIRCULANTE.
