Abstract

UN AMORTIGUADOR DE LIQUIDO-GAS, PARA CONTROLAR, POR EJEMPLO, EL RESPALDO DEL ASIENTO DE UN VEHICULO, QUE TIENE UN PISTON PRINCIPAL (26) QUE TIENE UN VASTAGO (18) Y DEFINE UNA PRIMERA Y SEGUNDA CAMARAS (30,31) LLENAS DE UN LIQUIDO. UNA PRIMERA Y UNA SEGUNDA VALVULAS NORMALMENTE ABIERTAS (34,84)Y UNA VALVULA DE CONTROL (74) QUE ES ACCIONADA EXTERIORMENTE POR UN VASTAGO DE CONTROL (62) CONTROLAN LA CIRCULACION DE LIQUIDO ENTRE LA PRIMERA Y LA SEGUNDA CAMARAS (30,31)A TRAVES DE UN CONDUCTO (42) EXISTENTE EN EL PISTON PRINCIPAL (26). CUANDO LA VALVULA DE CONTROL (74) ESTA ABIERTA, EL PASO DE LIQUIDO ACTIVA LA POSICION DEL VASTAGO (18) PARA AJUSTARLO. UN SEGUNDO PISTON (96)ESTA SOMETIDO A LA PRESION EXISTENTE EN LA SEGUNDA CAMARA (31) A TRAVES DE UNA TERCERA VALVULA NORMALMENTE ABIERTA (108) Y DEFINE UNA CAMARA LLENA DE GAS (100). EL SEGUNDO PISTON (96) SE MUEVE PARA COMPENSAR LAS VARIACIONES DE VOLUMEN CAUSADAS POR EL VASTAGO DE PISTON (18). EN EL CASO DE QUE EL VEHICULO EXPERIMENTE UN CHOQUE MECANICO VIOLENTO, EL REPENTINO INCREMENTO DE PRESION EN CUALQUIERA DE LAS CAMARAS LLENAS DE LIQUIDO (30,31), DEPENDIENDO DE LA DIRECCION DEL IMPACTO, HACE QUE LA PRIMERA VALVULA (34) O LA SEGUNDA (84) SE CIERREN CON EL FIN DE BLOQUEAR EL PASO DE FLUIDO Y BLOQUEAR EL VASTAGO DE PISTON (18) AUNQUE LA VALVULA DE CONTROL (74) ESTE ABIERTA. UN REPENTINO INCREMENTO DE LA PRESION EN LA SEGUNDA CAMARA (31) HACE TAMBIEN QUE SE CIERRE LA TERCERA VALVULA NORMALMENTE ABIERTA(108).
