Abstract
Un montaje de cierre de vástago de la válvula para un motor de combustión interna incluye una caja rígida anular dispuesta alrededor de una guía de válvula y un vástago de válvula. Un cuerpo elastomérico anular se encastra a presión dentro de la caja rígida anular e incluye una junta de cierre que se extiende radialmente hacia dentro en contacto hermético con el vástago de la válvula. El cuerpo elastomérico anular incluye un primer extremo axial de frente a la guía de válvula y un segundo extremo axial de espaldas a la guía de válvula. La caja rígida anular incluye una pared final que se extiende radialmente hacia dentro opuesta al segundo extremo axial del cuerpo elastomérico anular y que incluye un soporte de junta que se extiende axialmente de una parte interna de la pared final que se extiende radialmente hacia dentro y opuesta a una superficie radialmente interna de la junta de cierre que se extiende radialmente hacia dentro.
