  • Patent number: 6951165
    Abstract: A fuel pump for an internal combustion engine, comprising a housing (14) in which a piston (16) is guided. A working chamber is confined in areas by the piston (16). An eccentric shaft or camshaft acts on the piston (16) on its end furthest from the working chamber. A prestressing element (30) loads the piston (16) against the eccentric shaft or camshaft. In order to reduce the fabrication costs of the fuel pump, the invention provides that a support member (40) that is separate from the piston (16) is provided, which said support member is interconnected with the end region (36) of the piston (16) closest to the eccentric shaft or camshaft, and against which the prestressing element (30) bears.

  • Patent number: 6793786
    Abstract: An adapter (1) and electrochemical gas sensor (2) is provided with an electrochemical gas sensor housing (14) accommodating an electrolyte (13), with at least one measuring electrode (12) arranged therein and with a membrane (11), which screens the measuring electrode (12) from a measured gas and is permeable to the measured gas. The measuring sensitivity of an electrochemical gas sensor is increased by the adapter (1) having a gas-impermeable surface (15) extending in parallel to and at a spaced location from the membrane (11). The adapter (1) and the membrane (11) form a flow gap (10) for the measured gas delivered by a pump. The adapter (1) may be plugged onto the electrochemical sensor (2) at its outer edge (1a). The measured gas enters through a central opening (17), expands in the flow gap (10) radially to the outside and leaves same via the ring-shaped gap (16).

  • Patent number: 6317053
    Abstract: A switch cabinet is provided for protection of servers and other highly sensitive computer devices or miscellaneous equipment. The cabinet is configured as a protection cabinet with an interior isolated from the atmosphere. The interior is continuously provided with fresh air by a ventilator. Fresh air is controlled by early detection fire sensors shortly before passing through the ventilator. When fire breaks out, the early detection fire sensors activate gas bottles filled with the noble gas argon, so that argon can be introduced into the interior to extinguish the fire once fresh air supply has been stopped, thereby ensuring early and fast extinguishing of the blaze.

  • Patent number: 6230842
    Abstract: The invention relates to a method for lubricating the teeth of a gear unit having a hollow wheel with an inner set of teeth and at least one pinion with an outer set of teeth that meshes with the inner set of teeth, and a gear unit with a hollow wheel with an inner set of teeth and at least one pinion with an outer set of teeth, which meshes with the inner set of teeth. To assure reliable supply of lubricant to the teeth during the operation of the gear unit, the invention proposes that the lubricant is introduced in a targeted way into the interior of the hollow wheel. The invention further proposes a gear unit, which has a device for the targeted delivery of lubricant into the interior of the hollow wheel.
