  • Suction jet pump with ribs for guiding the flow of fuel
    Patent number: 7874812
    Abstract: In known devices for pumping fuel, suction jet pumps are used which are driven by the fuel flowing back from the internal combustion engine and pump fuel from a supply tank into an impoundment container of a fuel pumping unit. In known suction jet pumps, the suction power is limited by the fact that the fuel stream applies itself to the housing wall, so that the entire area of the fuel stream is no longer available for entraining fuel. The device of the invention lessens this effect by providing at least one rib between the first partial section of the fuel line and the mixing conduit.

  • Device for delivering fuel from a tank to an internal combustion engine
    Patent number: 7765990
    Abstract: A device for delivering fuel having a delivery unit, a main filter with a filter housing situated downstream of the delivery unit, and a drive line for driving a suction jet pump embodied in the filter housing of the main filter. As a result, the assembly and manufacture costs of the device are reduced.

  • Analogs of neurohypophysial hormones with inhibition effects
    Patent number: 4508645
    Abstract: The invention pertains to analogs of neurohypophysial hormones evidencing inhibition effects of the chemical formula I ##STR1## where A is CH.sub.3 CO or H, V is a residue of penicilamine or cysteine, B is CH.sub.3 or H, X is a residue of isoleucine or phenylalanine, Y is a residue of penicilamine or cysteine, and Z is a residue of leucine or lysine.These analogues evidence inhibition effects towards certain biological activities of neurohypophysial hormones.
