Abstract: A supply device and a method for building and operating a supply device of a filling station for liquid hydrogen are disclosed. The supply device has at least one storage tank for liquid hydrogen, and at least one pump for liquid hydrogen, the storage tank and pump being directly interconnected.

Abstract: The invention relates to a method for adjusting a hydrogen outlet temperature at a filling station, comprising inter alia a liquid reservoir (1), a cryopump (2), a heat exchanger (6), a gas reservoir (11) and a mixing point (7), wherein a cold hydrogen stream and a warm hydrogen stream are intermixed such that the temperature at the mixing point (7) lies between ?30 and ?45° C.

Abstract: A fluid energy machine, comprising a crank drive (A) and a drive device which is mechanically connected to the crank drive, wherein the drive device has two electric motors, the respective output members of which are mechanically connected to the crank drive is disclosed. The fluid energy machine is arranged within a housing which seals the fluid energy machine with respect to the surroundings and which is connected to a pressure-holding system. A method for operating a fluid energy machine of this type is further disclosed.

Abstract: Described as a filler-tank coupling, exhibiting a) a coupling plug (S), b) in which is arranged an axially movable conduit (R), c) a coupling socket (D) corresponding to the coupling plug (S), d) wherein the conduit (R) extends beyond the parting plane (T) into the coupling socket (D) in the coupled state, so that a media opening (9) provided in the front area of the conduit (R) becomes aligned with the inlet opening of a media line (L) arranged in the coupling socket (D), and e) means for joining the coupling plug (S) and coupling socket (D). According to the invention f) the conduit (R) has an insulated design (1), g) a first insulating body (2) is arranged at the front end of the conduit (R), h) the coupling socket (D) exhibits a second insulating body (6) that can move in an axial direction and corresponds to the first insulating body (2), and i) the conduit (R), first insulating body (2) and second insulating body (6) are sealed gastight (3, 4, 7).
