Abstract

Perfeccionamiento de una bomba aspirante e impelente, del tipo que comprende un pistón cilíndrico oscilante longitudinalmente en el interior de un mandrilado formando camisa, comprendiendo dicho pistón un vaciado en su superficie externa del que al menos un reborde es sensiblemente helicoidal para definir la carrera útil de compresión de dicho pistón por ajuste de su posición angular alrededor de su propio eje longitudinal, caracterizada porque dicha camisa comprende además al menos un aguzamiento de varios conductos aproximados sensiblemente transversales con preferencia paralelos, para la alimentación y la descarga del fluido en cada ciclo de la bomba y porque se ha previsto un medio de comunicación al menos momentánea entre al menos dos de dichos conductos aproximados, en la proximidad de sus orificios de salida en el lado del mandrilado.
