CAMSHAFT FOR A PUMP, IN PARTICULAR A HIGH PRESSURE FUEL PUMP, AND PUMP HAVING A CAMSHAFT

摘要

A camshaft (24), in particular for a pump (10), is proposed. The camshaft (24) has at least two cams (26, 28) which are arranged next to one another in the direction of the longitudinal axis (25) of the camshaft (24) and the cam elevations of which are arranged offset with respect to one another around the longitudinal axis (25) of the camshaft (24). An intermediate region (30) is provided between two adjacent cams (26, 28), and at least one bearing region (32) is arranged next to the cams (26, 28) in the direction of the longitudinal axis (25) of the camshaft (24). The intermediate region (30) runs in axial longitudinal sections which contain the longitudinal axis (25) of the camshaft (24), at a radial spacing (r1, r2) from the longitudinal axis (25) of the camshaft (24), which radial spacing (r1, r2), starting from the adjacent cam (26) with the smaller cam elevation (h1) in the respective axial longitudinal section, increases towards the adjacent cam (28) with the greater cam elevation (h2) in the respective axial longitudinal section.
