  • Hydraulic drive
    Patent number: 4202174
    Abstract: A hydraulic drive according to the invention comprises a gas hydraulic accumulator and a chamber whose volume is equal to at least the consumption of fluid by a User, e.g. a hydraulic cylinder of a press. This chamber is divided by a piston into two spaces. One of these communicates with the accumulator through a pipeline which is connected to a pump. The other space of the chamber communicates with the pump through a nonreturn valve, and with the User, through a closing device. This layout of the hydraulic drive steps up its reliability and ensures the possibility of controlling the pressure in the gas-hydraulic accumulator.
