Abstract:
A method for edge shaping in a high-pressure fuel reservoir, the fuel reservoir including an elongated tubular casing element having a longitudinal continuous recess, the continuous recess forming the interior space of the high-pressure fuel reservoir and being open at at least one end, the continuous recess being coupled to and forming a peripheral edge with at least one passthrough bore orifice, the method comprising:inserting an elongated actuation element into the continuous recess, the elongated actuation element having an end with a surface segment inclined with respect to a longitudinal axis of the continuous recess; introducing a pressure element having a surface portion into the continuous recess, the pressure element cooperating with the surface segment of the elongated actuation element; pressing the surface portion of the pressure element against the peripheral edge; and displacing material in a region of the peripheral edge by a pressure of the pressure element to provide a smoothing of an edge contour.
