  • Hydraulic pressure transformer
    Patent number: 5381661
    Abstract: The invention relates to a hydraulic pressure transformer, wherein a storage chamber and a work chamber are connected with each other via an overflow bore into which a plunger piston dips to generate a pressure stage and thereby separates the two chambers for generating a high pressure in the work chamber. An additional connecting conduit with a check valve is provided between the work chamber and the storage chamber.

  • Hydro-pneumatic pressure transformer
    Patent number: 5377488
    Abstract: A hydro-pneumatic pressure transformer with a storage piston fixed between storage oil and compressed air, which furthermore is centrally penetrated by a plunger piston, wherein, for the separation of oil from water, relief grooves are provided on the jacket face as well as in the wall of the central bore, which are connected with each other and are pressure-relieved via a ventilating bore leading to the exterior.
