Abstract
Perfeccionamientos en bombas, caracterizados por comprender un cuerpo de bomba, que proporciona un recipiente de fluido en su interior; un paso de entrada al recipiente de fluido; un paso de salida en el cuerpo de bomba; un bloque de cilindros montado en el interior del recipiente de fluido; una serie de cámaras de cilindros en bloque; un pistón en cada cámara; medios de impulsión en el cuerpo de la bomba, para comunicar movimiento alternativo a los pistones, entre posiciones anterior y posterior; medios que conectan cada una de las cámaras de cilindros al paso de salida; un paso de entrada para cada cámara de cilindro del bloque y, además, por disponerse primeros y segundos medios de control, aquellos dependientes de la presión del fluido en el paso de salida, para mover el bloque de cilindros a fin de reducir el volumen efectivo de salida de la bomba a un nivel predeterminado, inferior al máximo cuando la presión de salida excede de un primer nivel de presión; el segundo medio de control,independiente del primero, está ligado con un segundo nivel de la presión del fluido en el paso de salida, superior al primer nivel de presión citado, para mover el bloque de cilindros a fin de reducir el volumen esférico de salida de la bomba, para impedir que la presión máxima de salida exceda del segundo nivel de presión.
