Energy efficiency increasing system for hydraulic devices

A hydraulic pressure intensifier system, characterized in that it comprises:

• a main actuation subsystem;
• and directional change subsystem:
• wherein said main actuation subsystem comprises an angular-power-generating main motor, a pump connected to said motor and to a fluid reservoir, which sucks said fluid and fluidly displaces it;
• a means for generating and increasing pressure to provide fluid at a first pressure comprising;
• a first piston which inside it has:
• a plunger that moves linearly from an initial position to a final position and a travel limit sensor at each end of said piston;
• a 2-way valve at each outer end of said piston, which restricts or allows the passage of fluid to the interior or exterior thereof;
• a pressure control valve, fluidly connected to said 2-way valves, which has the function of accumulating and increasing said first pressure to a predetermined parameter to obtain a second pressure;
• a second piston fluidly connected to the pressure control valve, to receive the fluid with said second pressure, said second piston comprises inside:
• a plunger that moves linearly from an initial position to a final position and a travel limit sensor at each end of said piston;
• a 2-way valve at each outer end of said second piston, which restricts or allows the passage of fluid to the interior or exterior thereof, wherein said second piston increases the second pressure of the fluid to obtain a third pressure twice as high than the first pressure;
• a hydraulic motor, fluidly connected to said 2-way valves, which receives the fluid with the third pressure for its later use in other systems which require some work;
• a fluid cooling means, which cools the fluid coming from the hydraulic motor to send it to the fluid reservoir, and wherein said directional change subsystem comprises an angular-power-generating secondary motor, a second pump connected to said secondary motor and to said fluid reservoir, which sucks said fluid and fluidly displaces it;
• a pressure accumulator that receives the fluid displaced by the pump and that has the function of increasing the pressure in said fluid;
• a pair of electrovalves fluidly connected to said pressure accumulator to receive and direct the fluid with increased pressure towards the first and second pistons to return the plungers to their initial position to start a new work cycle, wherein said directional change subsystem operates parallel to and independently from said main actuation subsystems to end a complete cycle and repeat it indefinitely while the system is in operation.
