摘要

The device has a rod (39) for hermetically applying a ball (41) on a tapered hydraulic seat (61) of a nozzle (33) of a pressure regulator. The rod has an end (59) comprising a partial reception and guiding cavity (1) to laterally guide the ball with respect to an axis (3) of the seat. The cavity has a functional play equal to or greater than a distance between the axis of the seat and an axis of the rod. The ball comprises a sphere segment-shaped surface that is in contact with an opposite surface of the seat. An independent claim is also included for a high-pressure diesel injection device.
