ABSTRACT:
The invention relates to a fuel injection pump for internal combustion engines with a pump plunger (18), a drive shaft (11) for the actuation of the pump plunger (18) and a rotational-angle sensor (30) for detecting the angular position of the drive shaft (11), the pulse generator of which is designed as a generator wheel (32) seated firmly in terms of rotation on the drive shaft (11) and the pulse pick-up (31) of which is held on a carrier ring (35) seated rotatably on the drive shaft (11). For the purpose of narrowly toleranced exact association of the pulse generator wheel (32) and the pulse pick-up (31) both in the radial and in the axial direction, the pulse pick-up (31) is accommodated in a sensor housing (40) and this housing is fixed positively and frictionally on the carrier ring (35) by means of plug-in elements. Formed on the sensor housing (40) are sliding surfaces (41, 42), which rest on opposite sides of the pulse generator wheel (32), and a stop surface (46) which corresponds in the radial direction to a stop surface on the carrier ring (35) (FIG. 8).
