    摘要: An energy storage device having: a high-temperature regenerator containing a solid, particularly porous storage material (S); a working gas (A) as the heat transfer medium to transfer heat between the storage material (S) and the working gas (A) flowing through; and a charging circuit and a discharging circuit for the working gas (A). The charging circuit is designed such that starting from a pre-heating unit at least one first heat transfer duct of a recuperator, a first compressor (HO), the high-temperature regenerator, a second heat transfer duct of the recuperator and then a first expander are interconnected, thus forming a circuit, so as to conduct fluid. The first compressor is coupled with the first expander, and the first compressor forms part of a first piston machine (K1) and the first expander forms part of a second piston machine (K2), the piston machines (K1, K2) being operable either as a compressor or as an expander such that the first compressor of the charging circuit forms a second expander in the discharging circuit and that the first expander of the charging circuit forms a second compressor in the discharging circuit. The high-temperature regenerator can be connected to either the charging circuit or the discharging circuit to conduct fluid and can be controlled such that the high-temperature regenerator, the compressor and the expander form either part of the charging circuit or part of the discharging circuit. The charging circuit, the discharging circuit and the high-temperature regenerator have the same working gas (A) so that the working gas (A) comes into direct contact with the storage material of the high-temperature regenerator both in the charging circuit and in the discharging circuit.

    摘要: The invention relates to a fluid-tight cable duct (1) which is used to guide a cable (2) into a chamber (3) which can be impinged upon by pressure, and which comprises a housing (4), at least one cable (2) and one first and one second seal (5a, 5b) which can be pressure-loaded. The two pressure-loaded seals (5a, 5b) and the housing (4) define an inner hollow chamber (4d), and the cable (2) enters into the inner hollow chamber (4d) via the first seal (5a), through which the inner hollow chamber (4d) extends, and exits the inner hollow chamber (4d) via the second seal (5b). The inner hollow chamber (4d) comprises a pressure discharge opening (4c) which leads into an outer chamber (6) which is located outside the chamber (3) which can be impinged upon by pressure.
