Embodiment Construction
[0040]The “HYDRAULIC PRESSURE GENERATION UNIT WITH PNEUMATIC ACTUATION” herein consists of at least one pump, in a preferred embodiment of the invention by two pumps (1 and 2) assembled in parallel, one of them (1) having the volume and diameter of the hydraulic chamber (1 A and 1B) smaller than the volume of the hydraulic (2 A and 2B) of the complementary pump (2); however both having the same diameters as the upper and lower pneumatic plungers (3 and 4), respectively. The central body of the pumps (1 and 2) is a pneumatic cylinder (5) with a passer shaft (6) shaping a medial plunger (7) and two symmetrical and opposite hydraulic plungers (8 and 9) at the ends, which slide on a hydraulic sleeve (10 and 11). Pumps (1 and 2) having an automatic reversing system better depicted by upper (12) and lower (13) pneumatic reversing valves in a position such that it can be touched by the pneumatic plunger (7) that, in combination with the action of a pneumatic directional valve (14), directs...
