  • Switchable support element
    Patent number: 6425358
    Abstract: A switchable, hydraulic support element (1) requiring only a small design space is proposed. For achieving this, a bore (16) for a slide (23) is arranged laterally of a pressure piston (10) of a hydraulic clearance compensation element (11) in the inner element (7) and is configured as a pocket bore. This dispenses with the stacked arrangement of the bore in the inner element and the clearance compensation element on top of each other as seen in prior art. At the same time, the slide (23) is installed in a housing (19) that extends in the cylinder head (5).

  • Method for the integration of fuel cells into electrochemical plants
    Patent number: 6423203
    Abstract: The invention describes a method for the direct connection of fuel cells to electrolyzers of electrochemical plants producing hydrogen as a by-product. The by-product hydrogen is fed to the fuel cells and the electric energy thereby produced is transferred to the electrolyzers, with the consequent saving of the overall energy consumption. The direct coupling avoids the need for DC/AC converters or voltage adjusters and may be effected either in series or in parallel. In the latter case the fuel cell are assembled in modules, the number and voltage of which is regulated by means of interrupters activated by a computerised control and supervision system. As an alternative, the voltage of the modules may be varied by varying the pressure of the air fed to the fuel cells.

  • Device for adjusting the angle of rotation of a camshaft
    Patent number: 6418897
    Abstract: The invention concerns a device for the angular adjustment of a camshaft relative to the crankshaft of an internal combustion engine, particularly a vane-type adjuster (1) comprising a stator (12) that is driven by the crankshaft preferably through a traction element and a drive pinion (11), and a vane rotor (18) that can be pressurized by pressure oil and is rotationally fixed to the camshaft while possessing a means, preferably an axially displaceable fixing pin (37) for effecting a releasable, rotational fixing of the vane rotor. The drawback of oil leakage in common vane-type adjusters is avoided by the fact that all components of the vane-type adjuster (1) that have contact with pressure oil are arranged in an oil-tight housing (2).
