Abstract
La presente invención se refiere a amortiguador telescópico con una caja y con un vástago de émbolo que pasa por la caja en el sitio de la pared y obturado con respecto a la caja por un sello, caracterizado por que comprende: un anillo labial interno de PTFE (politetrafluoretileno) y de un anillo de apoyo externo de hule, el anillo labial y el anillo de apoyo están integralmente unidos y definidos axialmente por los dos costados mediante las caras de extremo que se convierten la una en la otra; el anillo labial está provisto cuando menos de una orilla selladora delimitada por dos superficies cónicas convergentes; la superficie cónica colocada por delante de la orilla selladora en dirección hacia la cámara obturada encierra un ángulo cónico mayor que la superficie cónica opuesta; el anillo de apoyo superpone el anillo labial en la región de la superficie de contacto recíproca sobre aquel lado volteado a la cámara que se debe obturar, cuando menos con un reborde de apoyo que se proyecta hacia adentro; el reborde de apoyo está delimitado por dos superficies cónicas que cruzan; las superficie cónica volteada a la cámara obturada tiene un ángulo cónico mayor que la cara cónica remota de la misma; por delante del reborde de apoyo está colocada una cara cilíndrica que se extiende fundamentalmente en sentido cilíndrico, en dirección a la cámara obturada; la superficie cilíndrica tiene un largo axial que es cuando menos tan grande como la distancia, medida en la misma dirección, de la orilla selladora hacia la cara de extremo; el anillo labial y de apoyo están unidos por dos sistemas adhesivos; las caras de extremo se extienden fundamentalmente paralelas; y las caras de extremo se extienden colocadas fundamentalmente en sentido perpendicular al eje sellador.
