Abstract

Conjunto de bomba de pistón y cilindro que incluye un cilindro; un pistón montado en el cilindro de modo que pueda deslizarse en sentido axial con relación al cilindro; y una junta de estanqueidad entre el pistón y el cilindro, caracterizado porque la junta de estanqueidad (1) incluye una porción interna anular (2) acoplada herméticamente con el pistón (6); una porción de placa (4) que se extiende radialmente hacia el exterior y axialmente hacia adelante a partir de la porción interna anular (2) a lo largo de una pared de soporte (9) formada en el pistón (6) y que se termina en un punto adyacente a la pared del cilindro y una porción externa anular (3) que se extiende axialmente hacia adelante a partir de la porción de placa (4), con lo cual durante una carrera hacia adelante (flecha x) del pistón (6) en el interior del cilindro, la porción anular externa (3) se acopla herméticamente con la pared del cilindro y la, junta de estanqueidad (1) está soportada en la pared de soporte (9) y durante una carrera de retorno del pistón (6) la junta de estanqueidad (1) se deforma por flexión de tal manera que todas las partes de la junta de estanqueidad adyacentes a la pared del cilindro se desplazan radialmente hacia el interior alejándose de la pared del cilindro para permitir la circulación del fluido más allá de la junta de estanqueidad (1).
