Abstract
Perfeccionamientos introducidos en una bomba o motor con desplazamiento variable y con un disco oscilante ajustable en su inclinación a través de al menos un cilindro de ajuste alimentable por medios hidráulicos, y con una válvula de control controlada por piloto dispuesta junto al alojamiento de bomba, que es ajustable desde una posición neutra a dos posiciones extremas que hacen posible la aportación o salida hacia o desde el cilindro de ajuste, y tiene un manguito de válvula y una corredera de pistón desplazable dentro de aquél, siendo ajustable la corredera de pistón por medio de una señal de entrada para la comunicación del cilindro de ajuste con un manantial de presión o con un colector desde su posición neutra a una posición extrema y estando unido el manguito de válvula desplazablemente y a través de un varillaje de retorno con el disco oscilante, caracterizados porque el varillaje de retorno está estructurado como árbol de retorno dispuesto en el eje de basculación del disco oscilante, el cual árbol de retorno se aplica por un extremo al disco oscilante y se extiende por el otro extremo a través del alojamiento de bomba hasta la válvula de control y allí se aplica al manguito de válvula a través de una conexión que tiene una distancia radial con respecto al eje de basculación.
