摘要： A machine press is provided in which at least one hermetically sealed hydraulic drive unit is switchable from a working mode, in which a base pressure above ambient pressure is continually exceeded, into a rest mode. To this end, in parallel with a pressure converter, to the high-pressure side of which a pressure store and a raising working chamber of a cylinder piston unit are connected, a bypass is provided, having a first blocking valve that is controllable by a control unit and, in its blocking position, blocks the through-flow direction from the high-pressure side of the pressure converter to the low-pressure side. Furthermore, the low-pressure side is connectable to a lowering working chamber via a second blocking valve controllable by the control unit. The pressure output of the hydraulic unit is connectable to the raising working chamber via a third blocking valve controllable by the control unit.

摘要： A method and apparatus for conversion of heat into liquid fluid power includes at least two hydropneumatic (hp) accumulators, each having a gas reservoir and a liquid reservoir therein separated by a movable separator. Liquid added to a liquid reservoir of a first accumulator causes gas compression in the gas reservoir of the accumulator. Gas is conducted from the first accumulator through a heat exchanger and into a gas reservoir of a second accumulator. Expansion of the gas in the second accumulator causes working liquid to be expelled from the second accumulator. After expansion of the gas in the second accumulator, working liquid is added to the liquid reservoir of the second accumulator gas is conducted through a cooling heat exchanger to the gas reservoir of the first accumulator, causing working liquid to be expelled. The fluid power produced through the expelled working liquid is stored or utilized to operate hydraulic devices.

摘要： A fluid pressure increasing/decreasing machine can continuously supply an output pressure to a destination of supply by converting an input pressure from a source of supply. A control device selects at least one input pressure chamber and at least one output pressure chamber from among at least three pressure chambers in a fluid pressure cylinder or a plurality of fluid pressure cylinders operating inter-connectedly, the input pressure chamber being supplied with the input pressure, the output pressure chamber creating the output pressure including a pressure higher than the input pressure and a pressure lower than the input pressure. A flow control valve causes the selected input pressure chamber to communicate with the source of supply, and the selected output pressure chamber to communicate with the destination of supply. At least one of the pressure chambers is capable of being either of the input pressure chamber and the output pressure chamber.
