  • the pressure valve 2 is inserted, for example, in a bore provided in the fuel rail.
  • the feed line leads the fuel to the fuel feed connection 6 of the pressure valve 2; the flow line conducts the fuel from the fuel flow connection 8 of the pressure valve 2, for example, to a consumer or to a storage container, not shown.

To avoid unnecessary repetitions, please refer to the above
  • the pressure valve 2 can be, for example, a pressure control valve or a pressure control valve or a differential pressure control valve or a differential pressure control valve. Inside the pressure valve 2 there is, for example, a fuel chamber and a pressure control chamber. A diaphragm group separates the pressure control chamber from the fuel chamber.
  • the fuel inlet connection 6 leads into the fuel chamber.
  • the pressure control chamber of the pressure valve 2 is connected, for example, to a suction line of the internal combustion engine via a line which is not shown for clarity. Via the gas connection 10, for example, the negative pressure prevailing in the suction line can be passed into the pressure control chamber provided in the pressure valve 2.
  • transition point 16 On a lateral surface of the housing part 2, there is a transition point 16. At the transition point 16, the gas connection 10 flows into the housing part 2 of the pressure valve 2.
  • the transition point 16 between the gas connection 10 and the housing part 4 is designed so that a tight Connection between the gas connection 10 and the housing part 4 is ensured, that is to say that the interior of the pressure valve 2 is sealed off from the surroundings.
  • the gas connection 10 is, for example, a piece of pipe consisting of electrically conductive sheet metal.

  • the opening 18 is like this dimensioned that the gas connector 10 can be inserted into the opening 18 with little play.
  • the gas connection 10 is firmly connected to the housing part 4 using a connecting substance 24.
  • the connection takes place, for example, by soldering, in particular by brazing, or by welding.
  • the fusible connector 24 is preferably copper solder.
  • the connecting substance 24 is therefore usually very good electrical conductor.
  • a contact connection tab 20 is provided in the area of the transition point 16.
  • the contact connection tab 20 has a through hole 22.
  • the through hole 22 is dimensioned such that the tubular gas connection 10 can be inserted through the through hole 22. Because the gas connection 10 has a bulge 10a at its end protruding from the housing part 4, the gas connection 10 is inserted through the through hole 22 of the contact connection tab 20 when the pressure valve 2 is assembled before it is inserted into the opening 18 of the housing part 4.

  • Contact connection tab 20 can be done in a common operation. No additional effort is therefore required to attach the contact connection tab 20. Therefore, without requiring additional effort, an excellent, durable, electrically good conductive and absolutely safe connection between the contact connection tab 20 and the gas connection 10, 10 ⁇ or between the contact connection tab 20 and the housing part 4 can be created.
  • the end of the contact connection tab 20 protruding from the transition point 16 projects beyond the housing part 4.
  • This end of the contact connection tab 20 is designed in the form of a plug pin 20a.
  • the plug pin 20a is dimensioned such that an electrical plug coupling which is usually used in motor vehicles can be plugged onto this end of the contact connection tab 20.
  • the cable connects to an electrical pole of the motor vehicle, this electrical pole preferably also being the electrical ground of the motor vehicle. By plugging in the plug-in coupling, the cable can very easily be electrically connected to the contact connection tab 20. It is thereby achieved that the pressure valve 2 or the housing part 4 and / or the gas connection 10, 10 'are also electrically connected to a defined electrical potential when that Component, which the pressure valve 2 is installed, consists of an electrically non-conductive material.
  • the contact connection tab 20 is electrically securely and permanently permanently connected to the gas connection 10, 10 ′ and to the housing part 4 via the connecting material 24.
  • the connecting substance 24 forms a secure electrical connection between the contact connection tab 20, the housing part 4 and the gas connection 10, 10 '. Even if the gas connection 10, 10 'or the housing part 4 consists of an electrically non-conductive material, then there is still an electrical connection between the contact connection tab 20 and the other component made of electrically conductive material, the housing part 4 and the Gas connection 10, 10 ', guaranteed.
  • the connecting material 24 is made flowable by appropriate addition of heat, then it flows into the gap between the components to be connected. Because the connecting substance 24 has a large area in the
  • the contact connection tab 20 also provides mechanical reinforcement of the housing part 4 in the region of the opening 18 without any additional effort and in addition a mechanical reinforcement of the connection between the housing part 4 and the gas connection 10, 10 '.
  • the gas connection 10, 10 'and the housing part 4 are assembled from separate components. In conversion of this, it is also possible to form the gas connection 10, 10 'and the housing part 4 in one piece from the beginning. In this modification, too, it is advantageous to use the contact connection tab 20 at the transition point 16, at which the housing part 4 merges into the gas connection 10, 10 ', to be provided and to be fastened with the connecting substance 24, because in this case too, at the transition point 16, an excellent electrical connection between the contact connection tab is simple 20 and the housing part 4 or between the contact connection tab 20 and the pressure valve 2 is created.
