  • Publication number: 20220212698
    Abstract: A climate control system for a vehicle is suitable for combustible coolants and is a compact device for installation on a vehicle roof. A directly evaporating system includes an electrical switch box inside a compact climate control device for the vehicle and is partitioned so that, in the event of relevant leakages of assemblies containing coolant, the assembly cannot come into contact with the combustible coolant and no ignitable mixture can occur in these areas. The electrical box is a closed assembly and is operatively connected to an assembly by which air from areas outside the segments containing coolant is guided into the electrical box in such a way that a positive pressure is created in the electrical box to prevent combustible coolant from flowing into the electrical box.

  • Patent number: 11377334
    Abstract: An industrial truck having at least one hydraulic mast lift cylinder, which is connected to a hydraulic block via a hydraulic arrangement that limits a lowering speed of the mast lift cylinder. The hydraulic arrangement is formed to limit the lowering speed in a load-dependent manner to at least two maximum values.
