Definitions

  • a main advantage of the injection valve according to claim 1 is that it is possible to adjust the tension of the spring that biases the valve closing element in a valve closing position of the valve more precisely.
  • the upper first adjusting tube it is possible to determine the tension of the spring at a first step.
  • a second step allows for increasing the tension of the spring using the second lower adjusting tube. As a result, it is possible to adjust more injection valves to the predetermined requirements.
  • the first and the second tube 2, 3 can be made of copper alloy.
  • the adjusting tubes 2, 3 could be welded, swaged or glued to the inlet tube 1.
  • the inlet tube 1 could be realized as a welded tube, a seamless welded tube or a tube formed from a rolled thin sheet. It could be a flanged or a dished part, an extruded part, a press-forged part or a machined part from a solid rod.
  • the inlet tube could have different material thickness along the body.
