Abstract
Se describen varias cuñas que pueden ser utilizadas en una ménsula de restricción de un ensamble de bomba de chorro. El ensamble de bomba de chorro puede incluir una ménsula de restricción que tiene una ménsula superior y una ménsula inferior conectadas con un mezclador de entrada. Una cuña puede ser provista entre la ménsula superior y la ménsula inferior y un poste de cuña puede pasar a través de un orificio con ranuras de la cuña. Los extremos del poste de cuña pueden estar acoplados con las ménsulas superior e inferior. La ménsula de restricción también puede incluir un miembro tipo horquilla que rodea al mezclador de entrada y está conectado con un tubo elevador. La cuña puede incluir una superficie inclinada que está configurada para acoplarse con un cojinete de ménsula de restricción del miembro tipo horquilla. Las cuñas también pueden incluir superficies curvas internas que hacen contacto con el poste de cuña y las superficies curvas internas pueden ser parte de un inserto que puede insertarse en la cuña.
