Patents by Inventor Dominikus Hofmann

Dominikus Hofmann has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8245696
    Abstract: The invention relates to an area of intersection between a high-pressure chamber and a high-pressure duct. To increase the strength in the area of intersection, it is possible to round the area of intersection. The area of intersection includes at least one planar area or an area that is curved markedly less than the remaining area of intersection. The planar area may also be embodied as only nearly planar. The high-pressure chamber and the high-pressure duct are also called functional chambers. By means of the planar or nearly planar area, an intersection geometry is created, in which tensile stresses of the functional chambers that occur upon subjection to pressure are not superimposed directly and add up as they do in conventional intersection geometries.

  • Patent number: 7717087
    Abstract: A connection point of a chamber subjected to high pressure in a body subjected to high pressure of a high-pressure injection system for fuel at a bore extending substantially vertically through the body. In the chamber subjected to high pressure of the body, a cylindrically shaped pocket or an encompassing groove is embodied, into which the bore discharges, forming an intersection point.
