Abstract
The invention concerns a device for the direct recovery of hydraulic energy in a machine, comprising at least one single-acting storage cylinder-piston device with a storage cylinder, a storage cylinder-piston and a storage cylinder chamber, with at least one differential cylinder-piston device with a differential cylinder comprising a separate rod side and base side, and with at least one hydraulic accumulator, which may be connected to the storage cylinder-piston device and/or the differential cylinder-piston device, wherein the potential energy of the storage cylinder-piston device, which retracts under a compressive load, may be at least partially stored in the hydraulic accumulator.
Claims13
A device for direct recovery of hydraulic energy in a machine comprising,
- at least one single-acting storage cylinder-piston device with a storage cylinder, a storage cylinder piston and a storage cylinder chamber;
- at least one differential cylinder-piston device with a differential cylinder with a separated rod side and base side, and at least one hydraulic accumulator hydraulically connected to at least one of the storage cylinder-piston device and the differential cylinder-piston device;
- wherein a potential energy of the storage cylinder-piston device is stored at least partially in the hydraulic accumulator;
- and
- wherein the storage cylinder-piston device retracts under a compressive load.
