Abstract: The present invention discloses an implement, in particular an excavator or a machine for material handling, with an element movable via at least one working drive, wherein at least one energy recovery cylinder is provided for energy recovery from the movement of the movable element, which includes a chamber filled with gas. In accordance with the invention, a device for adjusting the temperature of the energy recovery cylinder is provided.

Abstract: The present invention relates to an implement, in particular an excavator or a machine for material handling, with an element movable via at least one working drive, wherein at least one energy recovery cylinder is provided for energy recovery from the movement of the movable element, which includes a chamber filled with gas. The energy recovery cylinder is equipped with a heat exchanger.

Abstract: The present invention relates to a working device having an element movable via at least one working cylinder, with at least one energy recovery cylinder being provided for recovering energy from the movement of the movable element and having a chamber filled with gas. In this respect, the chamber filled with gas is in operative communication with a pressure store which counters a pressure increase in the chamber filled with gas at least from a maximum pressure onward.
