摘要：apparatus for measuring and recording the angular position of the edges ofgrooves (18) extending axially, provided on a surface of a cylindrical hole and a cylindricalinternal surface of an external part (10), the device is characterized in that it comprises aclamp (82 a region (85) which is tightly pressed against the surface.the region (85) with anorifice (84) from the area (85) intimate contact, to a pressure chamber (88) 97) suppliedwith fluid, and the relative rotation of the workpiece (10) and the clamp (82) is

generated.the apparatus also includes a measuring device (not shown) is used to measurethe degree of the restriction imposed on the flow of a fluid from the orifice (84) so thatthe edges of the grooves passing in front of the orifice (84) during the relative rotationof the workpiece and the hoofa device for measuring the angular position (notrepresented) is also provided to measure the relative rotation, so that the angularpositions of the workpiece are recorded at the level of each position of relative rotationcorresponding to a degree pr\éd\étermin of restriction of the orifice (84) sothat successive edges of grooves passing in front of the orifice (84).
