ABSTRACT:
A hydro or oleopneumatic device comprises a pressure transformer consisting of a single or multiple pneumatic cylinder having one or a number of stages in which the piston is rigidly coupled to an accumulator. The accumulator piston discharges the liquid to a function jack which utilizes the energy produced by the pneumatic pressure. The pneumatic cylinder is not provided with compressed-air exhaust ports and is freely connected to a compressed-air reservoir at the working pressure. The volume VR of the reservoir is large in comparison with the volume VC of the pneumatic cyclinder, the ratio VC/(VR + VC) being equal to the permissible variation in the working pressure of the air according to the intended use of the device.
