Pressure-effected interconnection of a metal part and a plastic part

A device, comprising:

• a metal part;
• and
• a plastic part slid over the metal part with a press fit and forming a pressure-effected interconnector therewith;
• wherein the metal part has an outer wall with circumferential ribs, the ribs being arranged one behind the other in an axial direction, each rib having a respective back which outwardly rises from the outer wall in a slide-on direction of the plastic part, and a flank which sharply falls from a back end toward the outside wall, the metal part further having an annular groove located in front of each rib viewed in the slide-on direction of the plastic part, the outer groove being situated in the outer wall directly at a foot of the respective back.

A fuel valve for an internal combustion engine, comprising:

• a cylindrical valve body, having at least one fuel inflow duct which is formed in the valve body having an inflow opening situated in a wall of the cylinder body;
• and
• a fuel filter coupled to the cylindrical valve body and retained thereto by a press fit, the fuel filter having a hollow-cylindrical base element made of plastic and filter mesh which is embedded in the base element and covers the inflow openings, the base element of the fuel filter having a shape and being configured to be slid over the valve body;
• wherein the valve body has circumferential ribs disposed on a cylinder wall thereof, the ribs being disposed one behind the other in an axial direction, each of the ribs having a back which rises outwardly from the cylinder wall in the slide-on direction of the fuel filter, and having a flank which steeply falls from a back end to the cylinder wall;
• and wherein an annular groove is disposed in front of each of the ribs in the slide-on direction of the fuel filter, the groove being situated into the cylinder wall of the valve body directly at a foot of the back.
