Abstract: The invention relates to a system that intensifies hydraulic pressure, which comprises a main actuation subsystem and a direction-change sub-system. The main actuation subsystem comprises: a motor; a pump; a first piston with a plunger that moves linearly; a travel-limit sensor and a two-way valve at each end of the piston; a pressure control valve connected to the two-way valves; a second piston similar in always to the first and connected to the pressure control valve; a hydraulic motor connected to the two-way valves of the second piston to generate work; and a fluid-cooling means. The direction-change subsystem comprises a secondary motor, a second pump, a pressure accumulator and a pair of solenoid valves for the parallel and independent operation of the two-way valves of the main actuation subsystem.

Abstract: The invention relates to a pressure generator and to the novel features thereof, which is intended to multiply pressure output through the use of sealed chambers containing rodless pistons acting on the fluid which operates as a force transmitter and concentrates the force on the frusto-conical covers at each end of the piston. Owing to the taper of the covers, the force is directed toward the directional valves which are housed in the ends of the piston and distribute the pressure in an orderly manner through fluid conductors towards the hydraulic motor. The operation and novel features of said generator render these systems more efficient.
