  • Method and device for assembling an injection pump element
    Patent number: 5647320
    Abstract: A method and device for assembling and setting the injection pump elements in which the control rod is pressed against an elastically compliant stop in the form of a pin, which engages one end of a longitudinal groove of the control rod. In this position of the control rod, the injection pump elements have an adjusting pin inserted into a recess of the control rod, which adjusting pin is connected by a control arm to the plunger of the injection pump element, and the injection pump element is rotated so that the control arm lies against a stop of the injection pump element. The injection pump element is then bolted in place in this position.By this method and device the control rod, during assembly, is intentionally set a short distance further than it is possible to move it in normal operation by the controller.
