Abstract

Perfeccionamientos en bombas de desplazamiento variable, del tipo que comprende un elemento de eje conductor; por lo menos un pistón y una placa motriz montada alrededor de un eje geométrico desplazado del eje geométrico del elemento de eje conductor y dispuesta con el pistón, y desplazada en respuesta a la presión del colector de descarga de la bomba para controlar la carrera del pistón ante una carga de empuje proporcional a la presión del colector de descarga que se transmite a la placa motriz, y medios para transmitir la carga de empuje, caracterizados porque se constituyen dichos medios por una carcasa de bomba que contiene un fluido un pistón de área diferencial dispuesto deslizantemente dentro de la carcasa y que coopera con la misma para forma una cámara para recibir una presión proporcional a la presión de descarga de la bomba; teniendo el pistón de área diferencial una cara que forma un cojinete de empuje, hidrostático; medios para dosificar el fluido al cojinete de empuje hidrostático; un elemento anular adyacente al cojinete de empuje hidrostático y desplazado en respuesta a la carga de empuje proporcionada por el mismo; y medios dispuestos con el elemento anular y la placa motriz y que responden al desplazamiento del elemento anular para transmitir el desplazamiento a la placa motriz.
