  • Patent number: 11746764
    Abstract: A dual pneumo-hydraulic pump unit is provided. The dual pneumo-hydraulic pump unit includes a central pneumatic cylinder that works in the center of two hydraulic piston pumps. The two hydraulic piston pumps are mounted parallel to the plunger of the central pneumatic cylinder, positioned one on each side. Compressed air or other pressurized gases are used to move the central pneumatic cylinder, as a source of motor energy to pump oil under pressure to a hydraulic pressure accumulator for later activation of hydraulic actuators.

  • Patent number: 11466705
    Abstract: The present patent of invention relates to a hydraulic unit (U) with a pneumatic cylinder (15) that works jointly with a servomotor (M), together with a ball screw (29) to together move a hydraulic piston pump (8), made up of a hydraulic plunger (7), with related sealing elements to prevent oil leaks, noise, metal-on-metal attrition and loss of efficiency, that is moved upwards and downwards using a ball screw (29) and a pneumatic cylinder (15), jointly with a servomotor (M) which, when moved, pushes the pressurized oil outwards while filling the opposite hydraulic chamber with an oil suction movement, the pumped oil entering a hydraulic pressure accumulator (25), where it remains idle to be used when required and being supplied by the up/down movement of the piston, generating continuous pumping, which is automatically stopped when the hydraulic pressure accumulator (25) is full and has reached the predetermined hydraulic pressure.

  • Publication number: 20220106969
    Abstract: A hydraulic unit is provided that includes a ball screw, which is driven by a servomotor, and both are configured to raise and lower two hydraulic sleeves of two hydraulic piston pumps, mounted in parallel and separately from one another. This is to draw hydraulic oil from an oil reservoir and pump this pressurized oil into one or more hydraulic pressure accumulators. When the hydraulic pressure accumulators are full, there can be an increase in hydraulic pressure activating a pressure sensor that can control the halting of the servomotor.

  • Publication number: 20210396218
    Abstract: The invention comprises a system containing a multipurpose hydraulic unit that can be used in machines and equipment, driven by low-pressure compressed air or other gases, comprising two hydraulic pumps that work together with a hydraulic pressure accumulator, where the main function of the hydraulic pumps is to pump oil to ensure that the hydraulic pressure accumulator (28) is always full, in which the pumping of oil begins with the supply of compressed air, which passes through the pneumatic directional valve (11) and is conveyed to the lower pneumatic chamber (22) or to the upper pneumatic chamber (4) to move the pneumatic cylinder and to push the hydraulic liners of the pumps, which pumps are assembled in parallel with the shaft of the pneumatic cylinder, each on one side, and as such, when the hydraulic chambers move, they exert a force on this volume of oil and force this stored oil out through the check valves to the hydraulic pressure accumulator, where it is kept under pressure and ready for use, and

  • Publication number: 20160230786
    Abstract: A “HYDRAULIC PRESSURE GENERATION UNIT WITH PNEUMATIC ACTUATION” in particular a multifunction unit activated by low pressure air, consisting of at least one pump (1), preferably two pumps (1 and 2), which are pneumatically automated, comprising a pneumatic cylinder (5) with a medial plunger (7), in addition to two symmetrical and opposite hydraulic plungers (8 and 9) limiting an upper hydraulic chamber (1 A and 2 A) and another lower hydraulic chamber (1 B and 2 B) having different volumes, wherein since they work in parallel and out-of-phase a reduced oil volume is required and the pulsating movement thereof is removed.
