Abstract

Perfeccionamientos en los sistemas de fluidos alternantes, que configuran un circuito hidráulico capaz de producir un movimiento alternativo sobre determinados elementos del mismo, caracterizados por conectar la línea de alimentación (25) de aceite a presión a un acumulador hidráulico (6) al que carga según un cierto volumen, a la cámara de retroceso (11) de un cilindro hidráulico principal (1) en la que empuja al émbolo principal (2) en sentido ascendente, a una cámara (17) de un cilindro hidráulico de pilotaje (4) en la que empuja al émbolo de pilotaje (5) a una posición extrema poniendo en comunicación entre sí dos (18 y 19) de sus cámaras.
