Abstract (en)
[origin: EP0931604A1] The probe (13) has a pressure fluid feed channel (14) connected to a fluid high pressure production unit. A sealing arrangement (24,25) for the hollow shaft (7) is provided on the section (21) of the cam (4) to be joined and in the area (19) of a bearing point. The sealing arrangement contains two sealing bodies (24,25) arranged axially spaced apart and around the probe. The sealing bodies limit the areas (19,21) of the hollow shaft to be widened, axially on both sides with support on the inside (27) of the hollow shaft. The sealing arrangement for the bearing point (20) contains a support tool, which in the usage position locates rigidly on the outside of the hollow shaft, leaving free the area of the hollow shaft to be widened, thereby covering the sealing bodies (24,25). Tools are provided for alignment, positioning and retention of the cam (4),
